HARD DISK SUPPORT
=-=-=-=-=-=-=-=-=
Windows 95
----------
Windows 95 includes built-in support for SCSI hard drives. If you attach
a new, unformatted, drive to your SCSI host adapter, you will need to
partition and format the media before you can use it. You can follow
these steps:
1.) Run Device Manager. You can do this by moving the mouse pointer
over "My Computer," clicking the right mouse button, and selecting
the "Properties" menu option.
2.) Select the "Device Manager" option.
3.) Expand the "Disk drives" tree to view your SCSI hard drives.
4.) Double-click on your newly added hard drive.
5.) Select the "Settings" option.
6.) If the "Int 13 unit" option is not turned on, then turn it on
and select OK. Reboot your system.
7.) Open up a DOS session (MS-DOS prompt).
8.) Run FDISK to partition your new drive as you desire.
9.) Reboot your operating system.
10.) When Windows 95 comes back up, double-click on "My Computer."
11.) Move the mouse pointer over your new drive letter(s), click the right
mouse button, and then select the "Format..." option.
12.) Follow the instructions to format your media.
NOTE: Under many configurations, steps 1-6 are not required as Windows
95 may have already marked your new disk drive as an "Int 13
unit." We still recommend that you take these steps to ensure
that your system is properly configured.
Windows 3.1/3.11 and DOS
------------------------
DOS and Windows 3.1x include built-in support for SCSI hard drives if your
new drive is under BIOS control (e.g. you booted from it). Please refer
to your host adapter documentation to learn more about whether or not
your SCSI host adapter includes an on-board ROM BIOS. In this case, you
can follow these steps:
1.) Boot to DOS.
2.) Run FDISK to partition your new drive as you desire.
3.) Reboot your operating system.
4.) Run FORMAT on your newly created drive letter(s)
If your new SCSI hard drive is not under BIOS control, you can follow
these steps:
1.) If running Windows 3.1x, install Adaptec EZ-SCSI for Windows 3.1x
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run SETUP.EXE
2.) If running DOS, install Adaptec EZ-SCSI for DOS
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run INSTALL.BAT
3.) After installing either Adaptec EZ-SCSI for DOS/Windows, reboot
your system.
4.) If you are running DOS, run AFDISK.EXE which is located in your
Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI). If you are running
Windows, you can use WINPART.EXE which is a Windows 3.1x
partitioning utility.
5.) Partition your new media as you desire.
6.) Reboot your operating system.
7.) At this point, your new drive is under ASPIDISK.SYS control
(Adaptec's disk driver for DOS).
8.) Although optional, we recommend that you run DOS FORMAT on your
new drive letter(s) so that the drive can be scanned for defects.
=-=-=-=-=-=-=-=-=-=-=-=
REMOVABLE MEDIA SUPPORT
=-=-=-=-=-=-=-=-=-=-=-=
Windows 95
----------
There are a number of ways to prepare your removable media for use under
Windows 95.
Windows 95, by default, will allocate one drive letter for your removable
media device. You can see the icon by double-clicking on "My Computer"
and seeing the "Removable Disk" text just below the drive's icon. If
you wish to treat your removable media as one large floppy, simply
insert the media into the drive and double-click on the icon. Windows
95 will automatically detect that the media is unformatted and ask you
if you would like to format the media.
Windows 95 also allows you to use partitioned removable media. For
example, if you have a 1 GByte removable cartridge, you might want to
partition the media into two 512 MByte partitions. To create a
partitioned removable media, you can follow these steps.
1.) Run Device Manager. You can do this by moving the mouse pointer
over "My Computer," clicking the right mouse button, and selecting
the "Properties" menu option.
2.) Select the "Device Manager" option.
3.) Expand the "Disk drives" tree to view your SCSI removable hard drive.
4.) Double-click on your newly added removable hard drive.
5.) Select the "Settings" option.
6.) If the "Int 13 unit" option is not turned on, then turn it on
and select OK. The "Removable" option should also be set. Reboot
your system.
7.) Open up a DOS session (MS-DOS prompt).
8.) Run FDISK to partition your removable media as you desire.
9.) Reboot your operating system.
10.) If you want to reserve multiple drive letters for your removable
media drive (e.g. multiple partitions), follow the next steps,
otherwise, skip to step #17
11.) Run Device Manager. You can do this by moving the mouse pointer
over "My Computer," clicking the right mouse button, and selecting
the "Properties" menu option.
12.) Select the "Device Manager" option.
13.) Expand the "Disk drives" tree to view your SCSI removable hard drive.
14.) Double-click on your newly added removable hard drive.
15.) Select the "Settings" option.
16.) In the "Reserved Drive Letters" area, you can select the starting
and ending drive letters for your removable media device. Save
settings and reboot your system.
17.) When Windows 95 comes back up, double-click on "My Computer."
18.) Move the mouse pointer over your new drive, click the right mouse
button, and then select the "Format..." option.
19.) Follow the instructions to format your media.
NOTE: Under many configurations, steps 1-6 are not required as Windows
95 may have already marked your new disk drive as an "Int 13
unit." We still recommend that you take these steps to ensure
that your system is properly configured.
Below is additional information you may find useful:
o We recommend that you boot Windows 95 without a DOS removable media
device driver (e.g. ASPIDISK.SYS). You can comment out such entries
from your CONFIG.SYS and then reboot. We have seen Windows 95
incorrectly create two drive letters for the same device when a
DOS removable media driver is resident. In addition, we have seen
some configurations where Windows 95 wouldn't allow us to set the
starting and ending drive letters when a DOS removable media device
driver is resident.
Windows 3.1/3.11 and DOS
------------------------
To prepare your removable media for use under Windows 3.1/3.11 and DOS,
you can follow these steps.
1.) If running Windows 3.1x, install Adaptec EZ-SCSI for Windows 3.1x
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run SETUP.EXE
2.) If running DOS, install Adaptec EZ-SCSI for DOS
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run INSTALL.BAT
3.) After installing either Adaptec EZ-SCSI for DOS/Windows, reboot
your system.
4.) If you are running DOS, run AFDISK.EXE which is located in your
Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI). If you are running
Windows, you can use WINPART.EXE which is a Windows 3.1x
partitioning utility.
5.) Partition your new media as you desire.
6.) Reboot your operating system.
7.) At this point, your new drive is under ASPIDISK.SYS control
(Adaptec's disk driver for DOS).
8.) Although optional, we recommend that you run DOS FORMAT on your
new drive letter(s) so that the drive can be scanned for defects.
Below is additional information you may find useful:
o Adaptec EZ-SCSI supports both 512 byte/sector media and 1024 byte/
sector media.
o If you would like to reserve multiple drive letters for your removable
media, you can use the /r command line switch. For example, if you
would like ASPIDISK.SYS to reserve two drive letters for your removable
media, you would have the following in your CONFIG.SYS:
device=c:\scsi\aspidisk.sys /d /r2
o Support for the Panasonic PD drive is also included. Note that you
should leave this device jumpered in its default two LUN mode.
=-=-=-=-=-=-=-=
CD-ROM SUPPORT
=-=-=-=-=-=-=-=
Windows 95
----------
Windows 95 includes built-in support for SCSI-2 CD-ROM drives and some
SCSI-1 devices. If your host adapter already has its miniport loaded,
Windows 95 will automatically detect and support your SCSI CD-ROM drive.
o We recommend that you boot Windows 95 without a DOS CD-ROM device
driver (e.g. ASPICD.SYS). You can comment out such entries from your
CONFIG.SYS and then reboot. We have seen Windows 95 incorrectly create
two drive letters for the same device when a DOS CD-ROM driver is
resident.
Windows 3.1/3.11 and DOS
------------------------
Adaptec's CD-ROM driver for DOS/Windows, ASPICD.SYS, has been written to
support any SCSI-2 CD-ROM drive and most SCSI-1 CD-ROM drives. Simply
run Adaptec EZ-SCSI and the correct additions will be made to your
CONFIG.SYS and AUTOEXEC.BAT.
Adaptec EZ-SCSI has been tested with CD-ROM drives from the following
vendors:
AIWA
Compaq
Chinon
Denon
Goldstar
Hitachi
IBM
LMS
Matsushita
NEC
Panasonic
Nakamichi
Philips
Pioneer
Plasmon Data
Plextor
Ricoh
Sanyo
Sony
TEAC
Texel
Toshiba
Yamaha
Below is additional information you may find useful:
o The following drives do not directly support Photo CD:
Chinon CDS 431
Denon DRD 253
LMS (Philips) CM 214
NEC CDR 72
NEC CDR 74 (NOTE: 74-1 and 84-1 do support single-
NEC CDR 84 session Photo CD)
By adding /XAEMUL to the ASPICD.SYS command line, in your CONFIG.SYS,
we will emulate support for single-session Photo CD on these drives.
o The following drives do not support parity:
NEC CDR 38
NEC CDR 55
NEC CDR 72
NEC CDR 73
NEC CDR 74 (NOTE: 74-1 and 84-1 do support SCSI parity)
NEC CDR 84
NEC CDR 210 (NOTE: 210P does support parity)
Please consult your host adapter documentation on how to disable parity
support on your SCSI host adapter.
o The following jukebox CD-ROM drives are fully supported:
Nakamichi MBR-7
Pioneer DRM 600
Pioneer DRM 604X
A drive letter will be assigned for each CD. Other jukebox CD-ROM
drives may require you to add /L to the ASPICD.SYS command line. You
may also need to modify your LASTDRIVE statement in your CONFIG.SYS.
o Some older SCSI CD-ROM drives do not support synchronous negotiation
properly. If you encounter problems using your CD-ROM drive, try
disabling synchronous negotiation. Please refer to your host adapter
documentation on how to do this.

32-BIT SUPPORT FOR WINDOWS 3.1/3.11
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Adaptec EZ-SCSI includes 32-Bit Disk Access support for Windows 3.1,
Windows 3.11, and Windows for Workgroups 3.11. To enable this support,
simply run the "32-Bit Disk Access" utility (FASTSCSI.EXE), and follow
the instructions. Please note the following:
o Our 32-Bit Disk Access device drivers only support Adaptec's bus-
mastering line of SCSI host adapters and Adaptec's AIC-6360/6370 based
SCSI host adapters. These host adapters use the following ASPI
managers:
ASPI2DOS.SYS
ASPI4DOS.SYS
ASPI7DOS.SYS
ASPI8DOS.SYS
ASPIEDOS.SYS
If your host adapter does not use one of these ASPI managers, our
32-Bit Disk Access utility will still allow you to enable or disable
SCSI write caching.
o If you are running Windows for Workgroups 3.11, and you are not able
to get 32-Bit File Access to work properly, the following comes from
Microsoft's Windows for Workgroups resource kit:
"32-bit File Access will not enable on a drive on which there are
open files during the initialization process of 32-bit File Access.
Because of this, 32-bit file access cannot be enabled through the
Control Panel Virtual Memory dialog when using a temporary swap file.
The temporary swap file is opened before 32-bit File Access
initializes and 32-bit File Access will not be able to enable on the
drive where the temporary swap file is located. There normally should
not be any open files at the time when 32-bit File Access is
initializing. If there are open files, they are probably the result
of some real mode TSR or a 3rd-party VxD."
o When 32-Bit Disk Access is enabled, you need to have the latest
WINASPI.DLL file in your Windows' SYSTEM subdirectory. If an older
revision is being used, you will experience protection faults when
running "ASPI for Windows" applications. EZ-SCSI 3.11 (and later)
will automatically install the correct WINASPI.DLL file. There are,
however, a few older packages that install the older WINASPI.DLL file.
If you are experiencing protection faults, while running "ASPI for
Windows" applications, you should check the date of WINASPI.DLL in
your Windows' SYSTEM subdirectory. If it is dated 1995 or later, you
have the correct file.
o 32-Bit Disk Access, in general, does not significantly improve
performance under Windows 3.1 or Windows 3.11. To get optimal disk
performance, you should use Windows for Workgroups 3.11 which, in
addition to 32-Bit Disk Access, includes support for 32-Bit File
Access. We are seeing the larger performance gains by enabling 32-Bit
Disk Access, 32-Bit File Access, and SCSI write caching.
o Our 32-Bit Disk Access driver cannot be used if you are also using our
SCSI Power Management driver. If you attempt to load both drivers, an
appropriate error message will appear when you run Windows. If you
encounter this message, and if you prefer 32-Bit Disk Access over SCSI
Power Management, simply run Adaptec's 32-Bit Disk Access utility and
select the "Install" option. It will detect the conflict and remove
the SCSI power management device driver.
o 32-Bit Disk Access only supports drives under BIOS control (INT 13h
drives). This does NOT include drives under the control of
ASPIDISK.SYS. Most of our SCSI host adapters allow you to have up to
8 SCSI drives under BIOS control.
o There is a known problem in Windows 3.1 and Windows 3.11 (does not
affect Windows for Workgroups 3.11) in that its 32-Bit Disk Access
solution only supports up to two hard drives. For example, if you
have three hard drives under BIOS control, only the first two would
be under 32-Bit Disk Access. If you encounter this situation, you
can upgrade to Windows for Workgroups 3.11 which does not exhibit
this limitation.
o Adaptec's 32-Bit Disk Access utility provides an uninstall option that
will remove our 32-Bit device drivers. If you would like to manually
remove the drivers, remove the following entries from the [386Enh]
section of your SYSTEM.INI file:
device=fastscsi.386
device=aha1540.386
device=aha1740.386
device=aic7770.386
device=aic7870.386
device=aic6x60.386
(NOTE: Not all of these drivers will be present in your SYSTEM.INI
file. Depends on what type of host adapter you have.)
o Enabling SCSI write caching can improve the overall performance of
your system. Many SCSI hard drives ship factory default with SCSI
write caching disabled. Our 32-Bit Disk Access utility will allow
you to enable or disable SCSI write caching on a per device basis.
We have found a few older drives causing system hangs, under intense
disk I/O, when write caching is enabled. In the unlikely event that
you encounter this situation, you can disable SCSI write caching at
any time by running our 32-Bit Disk Access utility.
o On some systems, when you enable 32-Bit Disk Access, Windows' Control
Panel incorrectly loads the IDE 32-Bit Disk Access driver even if you
only have SCSI disk drives. This will typically result in an error
message, while loading Windows, similar to the following:
"The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be
loaded on this computer because of interrupt conflicts."
If you encounter this, simply remove the line "device=*wdctrl" from
the [386Enh] section of your SYSTEM.INI file. Another option is to
run our 32-Bit Disk Access utility. It will detect that your
configuration is incorrectly loading the IDE device driver and ask if
you would like us to remove it.
o For the technical user: If you select to turn on SCSI write caching,
we will also turn on the AWRE (Automatic Write Reallocation Enabled)
bit in the Read/Write Error Recovery Page. If you select to turn off
SCSI write caching, the AWRE bit is set back to the factory default
setting (some drives ship factory default with AWRE set).
o If you have an AVA-2825 or AHA-1520A/1522A, with BIOS support for
floptical drives enabled, and you have a floptical drive connected
to your system, 32-Bit Disk Access is not supported under Windows
3.1/3.11.

DOS ASPI MANAGERS
=-=-=-=-=-=-=-=-=
Adaptec EZ-SCSI 4.0 includes a number of ASPI managers for Adaptec's
family of SCSI host adapters. Below is additional information on some
of Adaptec's ASPI managers.
ASPI2DOS.SYS
------------
ASPI2DOS.SYS is Adaptec's ASPI managers for AIC-6260/6360/6370 based SCSI
host adapters. Running Adaptec EZ-SCSI will automatically detect which
host adapter you have installed, which ASPI manager needs to be loaded,
and what the correct command line switches are.
o If you are using an Adaptec APA-1460 SlimSCSI, make sure you have
PCMCIA Card & Socket Services installed BEFORE running Adaptec
EZ-SCSI.
o If you have an IBM ThinkPad 360Cs or an IBM ThinkPad 755, and are
using the Adaptec APA-1460 SlimSCSI, you need to move the following
line to the last line inside your CONFIG.SYS file:
DEVICE=C:\EZPLY\$ICPMDOS.SYS
Note: If the directory for EZ-Play is different than the default, use
that directory instead. The above line uses the standard directory as
an example.
o If you have an APA-1460 (SlimSCSI) in your system and are installing
ASPI2DOS.SYS manually, you will need to add the following command
line switch to ASPI2DOS.SYS in your CONFIG.SYS file:
DEVICE = C:\SCSI\ASPI2DOS.SYS /D /PCMCIA /Z
o If you cannot suspend/resume properly on an AcerNote 735c, with an
APA-1460 (SlimSCSI), you're probably experiencing an I/O conflict
between the APA-1460 and your laptop. The AcerNote uses port 35F for
video control. You'll need to manually exclude this I/O port. With
SystemSoft Card and Socket Services, you can do this by editing the
CSALLOC.INI file and adding the line:
ioexclude=35F
o If you are using the Gateway 2000 Colorbook laptop with an Adaptec
APA-1460 (SlimSCSI), ASPI2DOS.SYS may fail during driver installation.
If you encounter this problem, you will need to go into the motherboard
CMOS setup utility and disable the "FastBoot" option.
o SCAM stands for "SCSI Configured AutoMagically." Without SCAM
support, the user needs to set jumpers or switches to assign a unique
SCSI ID to each SCSI device. With SCAM support, a host adapter can
determine which SCSI IDs are not in use, and assign a free ID to a
SCAM capable SCSI device. You can enable SCAM support by adding
/SCAM+ to your ASPI2DOS.SYS command line. For example:
DEVICE = C:\SCSI\ASPI2DOS.SYS /D /SCAM+
This will work with any AIC-6260/6360/6370 based SCSI host adapter
that does not have a BIOS enabled on the host adapter. If the host
adapter has a BIOS, and it is enabled, the command line switch is
ignored. If you have a SCAM capable BIOS (e.g. AHA-1530P), then you
can enable or disable SCAM support by running SCSISelect.
NOTE: There are very few SCAM capable SCSI devices available today.
Special firmware is required on the SCSI device. If you do not have
such a device, there is no need to use the /SCAM+ command line switch.
ASPI8DOS.SYS
------------
ASPI8DOS.SYS is Adaptec's ASPI manager for AIC-7850/7855/7870 based
PCI SCSI host adapters. Running Adaptec EZ-SCSI will automatically
detect which host adapter you have installed, which ASPI manager needs
to be loaded, and what the correct command line switches are.
o If you have an Adaptec PCI SCSI host adapter installed in your system,
and you have EMM386.EXE loaded from MS-DOS versions up to 6.2, your
system might hang if loading the ASPI manager after EMM386.EXE. This
has been fixed in the EMM386.EXE that ships with MS-DOS 6.22 and
later. If you experience this problem, you will either need to load
ASPI8DOS.SYS before EMM386.EXE, or upgrade to MS-DOS 6.22 or later.
If the ASPI manager detects a conflict, a message will be shown
explaining how to work around the problem. Other ASPI modules
(e.g. ASPICD.SYS) can continue to be loaded high.
o There are several techniques for a driver to determine if its PCI SCSI
host adapter is installed in your system. ASPI8DOS.SYS will determine
which is the best method, and has been written to work around the
EMM386.EXE problems discussed above. There are three command line
switches you can use to force the ASPI manager to use a specific
method. These are:
/MB - This command line switch will force the driver to use the
PCI BIOS calls (INT 1Ah) to scan for PCI SCSI host
adapters.
/M1 - This command line switch will force the driver to use the
"Mechanism 1" method for scanning for PCI SCSI host
adapters.
/M2 - This command line switch will force the driver to use the
"Mechanism 2" method for scanning for PCI SCSI host
adapters.
For example, if you want to force the ASPI manager to find your PCI
SCSI host adapter using PCI motherboard BIOS calls, your CONFIG.SYS
would be:
DEVICE=C:\SCSI\ASPI8DOS.SYS /D /MB
NOTE: Most PCI systems do not support all three methods for scanning
for PCI cards. It is recommended that you let the ASPI manager
determine which method is suitable.
o If you would like ASPI8DOS.SYS NOT to reset the SCSI bus, during
driver initialization, you can use the /NORST command line switch.
For example:
DEVICE=C:\SCSI\ASPI8DOS.SYS /D /NORST
If you would like ASPI8DOS.SYS to always reset the SCSI bus, during
driver initialization, you can use the /RESET command line switch.
For example:
DEVICE=C:\SCSI\ASPI8DOS.SYS /D /RESET
MCAM18XX.SYS
------------
MCAM18XX.SYS is Adaptec's ASPI manager for its AHA-2905/2920 PCI SCSI Host
Adapters. Running Adaptec EZ-SCSI will automatically detect which host
adapter you have installed, which ASPI manager needs to be loaded, and
what the correct command line switches are.
o The command line switches for MCAM18XX.SYS are currently not documented
in our on-line "Device Driver Reference" Windows help file. The
following command line switches are supported:
/u- - Force Asynchronous Data Transfers on a Host Adapter.
/norst - Disables Hard Reset during initialization.
/y - Disables parity checking.
/m1 - Force PCI bus scanning using the "Mechanism 1" method.
/m2 - Force PCI bus scanning using the "Mechanism 2" method.
/mb - Force PCI bus scanning using INT 1A.
/l - Enable multiple LUN support
o If installing the AHA-2905/2920 under Windows 3.1/3.11, Adaptec EZ-SCSI
will automatically install the AHA2920.386 and AXPT.386 device drivers.
The following options are supported by AHA2920.386. To enable an
option, add the following to the [386Enh] section of your SYSTEM.INI
file:
AHA2920 = [/l-] [/u-] [/y]
/l- - Disables multiple LUN support.
/u- - Force Asynchronous Data Transfers on a Host Adapter.
/y - Disables parity checking.
The following options are supported by AXPT.386. To enable an option,
add the following to the [386Enh] section of your SYSTEM.INI file:
EZSCSI_OPTIONS = [/d]
/d - Displays version, adapter, and device information.
MA358.SYS
---------
MA358.SYS is Adaptec's ASPI manager for its APA-358/358A parallel port
SCSI host adapters. Running Adaptec EZ-SCSI will automatically detect
which host adapter you have installed, which ASPI manager needs to be
loaded, and what the correct command line switches are.
o MA358.SYS, by default, will automatically detect the type of parallel
port you are using. You can use the /Mnm switch to force a specific
mode, and to set the amount of time that the MiniSCSI "Fast" read and
write cycles are delayed (parallel ports on some computers require
delays). You must specify values for both 'n' and 'm'.
The 'n' specifies the amount of delay. Allowable values for 'n' are 0
through 7, with each number representing a 125-nanosecond (ns)
increment. A value of 7, for example, adds an 875 ns (7x125) delay to
the cycles. The default of 0 specifies no delays.
The 'm' parameter determines the mode. The allowable values are shown
in the following table:
Value of 'm' Meaning
------------ ------------------------------------------------------
0 Auto-detect mode (the default). Automatically detects
the type of port and configures the APA-358/358A for
EPP if that port is detected to support EPP mode,
otherwise the port is set up as a standard parallel
port.
2 Forces unidirectional mode.
4 Forces bidirectional mode.
8 Assumes EPP 8-bit bidirectional mode. For this to
work, the parallel port must be set for EPP mode in
the CMOS setup program or by configuring jumper
settings on your EPP I/O card. For instructions on
using the CMOS setup program, see your motherboard
documentation. For instructions on configuring
jumpers on your EPP I/O card, see your EPP I/O card
documentation.
For example, if your parallel port is configured for EPP mode, and you
would like the default read/write delay, your CONFIG.SYS would contain
the following:
DEVICE=C:\SCSI\MA358.SYS /m08
If you change the MA358.SYS options in the config.sys file, turn the
computer OFF and then ON again to have the changes take effect. (Do
not simply reboot the computer using Ctrl-Alt-Del.)
o If you have an original NEC Ultralite Versa laptop, and MA358.SYS is
unable to detect the APA-358/358A SCSI host adapter, you should use
the /m20 command line switch. For example:
DEVICE=C:\SCSI\MA358.SYS /m20
o If you are using the APA-358 with an NEC Versa E or Versa V system,
which uses the Western Digital Super I/O chip for FPP Parallel Ports
(Chip #WD76C30), you should use the MA358NEC.SYS ASPI Manager in your
CONFIG.SYS file instead of the standard MA358.SYS ASPI Manager.
o If you are using an IBM ThinkPad 720 series computer, you should use
the MA358IBM.SYS ASPI manager in your CONFIG.SYS file instead of the
standard MA358.SYS ASPI manager.
o When using the APA-358/358A, you should not configure your parallel
port for ECP mode. Instead, you should configure the port for EPP
mode.
o MA358.SYS only supports one APA-358/358A in a system.
o If you are using the APA-358/358A, and you are backing up from a SCSI
disk drive to a SCSI tape drive, and you are using SMARTDRV, we
recommend that you disable SMARTDRV write caching. Leaving write
caching enabled can cause the backup to fail.

WINDOWS 3.1x/DOS GENERAL TROUBLESHOOTING
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
o The ordering in which the Adaptec EZ-SCSI installer displays SCSI host
adapters detected is dependent on a number of factors. If you have
multiple SCSI host adapters, and the ordering displayed is not as
you would expect, do not be alarmed. Adaptec EZ-SCSI will still
properly edit your configuration files.
o SMARTDRV 5.0 (in MS-DOS 6.2, Windows for Workgroups 3.11) now includes
caching for CD-ROM drives. There is a problem with SMARTDRV in its
support for XA formatted Compact Discs. If you experience "Not Ready"
errors, using SMARTDRV 5.0, add /E:2048 to your SMARTDRV command line.
For example:
C:\DOS\SMARTDRV /X /E:2048
o You should install Adaptec EZ-SCSI to a drive letter that exists at
boot time. This would NOT include RAM drives, network drives,
removable drives, etc.
o We have seen at least one case where an unstable video driver would
cause EZ-SCSI for Windows to hang during installation. If you are
experiencing similar problems, try using the standard VGA driver that
comes with Windows. If EZ-SCSI for Windows then installs properly,
you may want to contact your video card company for updated drivers.
o In the unlikely event that you encounter a time-out failure when
EZ-SCSI for Windows scans the SCSI bus, you should run EZ-SCSI for
DOS first. Let it modify your CONFIG.SYS to load the appropriate
ASPI managers; reboot your system. You should then be able to run
EZ-SCSI for Windows.
o If you have an AHA-2740W/2742W or AHA-2940W (Wide SCSI Host
Adapter), the SCSI Interrogator for Windows (SHOWSCSI.EXE) will only
show icons for SCSI IDs 0-7. You will not see IDs 8-15.
o The SCSI Power Management Utility requires that the following line
be present in your SYSTEM.INI file under the [386Enh] section:
device=VSCSIPWR.386
The first time you run SCSI Power Management you will be prompted to
install the above driver. If you wish to disable the SCSI Power
Management functions, you can remove this line from your SYSTEM.INI
file in your WINDOWS subdirectory.
o An issue with EMM386.EXE from DOS 6.2, and earlier, can cause problems
with PCI systems. The HIGHSCAN option can overwrite the PCI BIOS area
on some PCI systems, making the PCI BIOS detection useless. If your
Adaptec PCI SCSI host adapter is not detected, be sure to remove the
HIGHSCAN option from EMM386.EXE in your CONFIG.SYS file.
