CMD PCI64x 32-Bit Local Bus master IDE Windows NT 3.5x Driver Installation Instructions
-------------------------------------------------------------------------
You have to copy all the files in this directory except readme.n35 to the
root directory of the diskette before installation.
After you have installed WINNT 3.5x, follow these steps:
1) From the Program Manager, double click on "Windows NT Setup" in the
Main group.
2) Select "Options/Add/Remove SCSI Adapters..."
3) Click on Add.
4) The "Select SCSI Adapter Option" dialog box will appear; select
"Other (Requires a disk from a hardware manufacturer)" from the
"Adapter:" list box.
5) The "Insert Diskette" dialog box will appear; insert the CMD
driver diskette into Drive A: and type "A:\ NT35" into dialog box.
6) The "Select OEM Option" dialog box will appear; select
"CMD 64xx 32-Bit Local Bus IDE Adapter" and click "OK."
7) The "Select SCSI Adapter Option" dialog box will appear; click on
the "Install" button in the dialog box.
8) The "Windows NT Setup" dialog box will appear; click on the
"Continue" button in the dialog box.
9) If installation is successful, the "SCSI Adapter Setup" dialog box will
reappear, and "CMD 64xx 32-Bit Local Bus IDE Adapter" will be listed as
an installed driver.
10) Reboot your system to load the CMD IDE driver. Verify that it is
working properly. The following steps are optional, for those who
are interested in getting maximum performance.
11) In order for the driver to load performance optimizations for your
IDE drives, you must specify your Local Bus clock speed in MHz.
Valid values are between 20 and 50. IF YOU ARE NOT SURE OF YOUR LOCAL
BUS CLOCK SPEED, DO NOT PROCEED UNTIL YOU ARE SURE OR USE 0.
PCI-Bus: If you are using a 25MHz or DX2-50 processor, your Local Bus
speed is probably 25. Otherwise, it is probably 33.
12) From the Program Manager, select File/Run and type in "REGEDT32"
13) In the HKEY_LOCAL_MACHINE subwindow, open the
SYSTEM/CurrentControlSet/Services/Csa64x35/Parameters folder.
14) Click the Radix/Decimal button. Double click on LocalBusSpeed and
enter your Local Bus clock speed (e.g., 25,33,40,50, etc.). Be sure
to click on the Radix/Decimal button before clicking OK. To disable
drive optimizations, enter 0.
15) Reboot your system, and the driver will load drive optimizations.
16) Run the INSTALL.BAT from the NT35 directory in the CMD installation
diskette. For instance, if the diskette is in drive A,
A:
CD \NT35
INSTALL A:
Parameters:
NOTE: Unless otherwise stated, all parameters below are specified in
DECIMAL. Therefore, you must click on Radix/Decimal before
entering the value.
BusMasterRegister:
This option allows you to override the DMA base address register
value (Base Address Register 3, offset:20h in PCI configuration
space). You should not change the value of this parameter, unless
the DMA operation fails due to BIOS problems. By default, the
driver automatically checks the DMA base address register for
validity. If a valid value is encountered, the driver will use it;
if an invalid DMA base address register setting is detected, the
driver will override it with value 500h. However, if port 500h
conflicts with other hardware in your system, you may need to
select an alternate port address.
0 = use the default value of the DMA base address (default)
xxx = DMA base address register value in hexadecimal. Make sure the
port address you choose does not conflict with other hardware;
otherwise, it may cause your system to hang.
EnhancedIDE:
0 = driver will not set-up ATA timing modes
1 = driver will set-up ATA timing modes on Primary IDE only
2 = driver will set-up ATA timing modes on Secondary IDE only
3 = driver will set-up ATA timing modes on both IDE channels (default)
NOTE: 0-3 are useful if your BIOS sets up ATA timing modes
automatically, and you don't want to override it. If LocalBusSpeed
is 0, then EnhancedIDE is interpreted as 0.
LocalBusSpeed:
0 = disable setting of ATA timing modes
25-50: Local Bus Speed in MHz. Setting this parameter to your local
bus speed allows the driver to set-up the drives and PCI-064xx
for fast operation according to the ATA spec. Here are some
guidelines for local bus speed:
486 CPU's:
If you have a 486-25, DX2-50, or DX4-75 processor, your Local
Bus speed is probably 25. Otherwise, it is probably 33.
Pentium CPU's:
If you have a Pentium 60 or 90, your Local Bus Speed is probably
30. If you have a Pentium 66 or 100, your Local Bus Speed is
probably 33.
PrimaryIDE:
16 = use 16-bit access for Primary IDE port
32 = use 32-bit access for Primary IDE port (default)
SecondaryIDE:
0 = disable Secondary IDE port (default)
16 = enable PCI Secondary IDE port in 16-bit mode
17 = support external 16-bit ISA secondary IDE port
32 = enable PCI Secondary IDE port in 32-bit mode
UseLbaMode:
0 = use CHS mode on all drives (default)
1 = use LBA mode on drives which support it
ATA PIO/DMA Timing Mode Overrides
---------------------------------
Some drives may have firmware bugs causing them to report
incorrect transfer mode information to the driver. Incorrect ATA
PIO/DMA timing modes may cause system boot failure or data
corruption. By default, the driver automatically selects
the fastest mode which a drive claims to support. The user can
override this mode by using the following options:
WARNING: The driver does no sanity checking on drives for which
PrimaryMasterOverride, PrimarySlaveOverride,
SecondaryMasterOverride, SecondarySlaveOverride is specified.
If you use this option to set a drive to an unsupported
transfer mode, it may cause data corruption!
PrimaryMasterTransferMode:
1 = PIO (default). Set the drive to use the fastest possible PIO mode.
If you want to override the drive with a faster mode or a slower
mode, then enter the new mode value in PrimaryMasterOverride
option. PIO mode ranges from 0 to 4.
2 = Multiple Word DMA override. You can use this value to override
transfer mode on the primary master drive. In order to use
this option you must specify the mode number in the
PrimaryMasterOverride option. The multi-word DMA mode ranges
from 0 to 2.
3 = Single Word DMA override. You can use this value to override
transfer mode on the primary master drive. In order to use
this option you must specify the mode number in the
PrimaryMasterOverride option. The single-word DMA mode ranges
from 0 to 2.
4 = Enable DMA. Drives which support DMA transfer will be set to DMA
mode. Drives which only support PIO transfer will be set to
PIO mode. You may override a specific drive to DMA mode by
setting PrimaryMasterTransferMode to 2 or 3 and then entering
the mode override in PrimaryMasterOverride.
PrimaryMasterOverride:
255 = don't override vendor-specified ATA PIO/DMA timing mode
for the master drive on primary channel (default).

PrimaryMasterTransferMode to 3.
0-5 = override vendor-specified ATA PIO timing mode for primary master
drive with specified mode. The PrimaryMasterTransferMode must
be set to 1.
PrimarySlaveTransferMode:

2 = Multiple Word DMA override. You can use this value to override
transfer mode on the primary slave drive. In order to use
this option you must specify the mode number in the
