Introduction
------------
ADVDISK is an ASPI Disk Driver for MS-DOS. It is an installable
device driver that is loaded in the CONFIG.SYS file. To install,
copy ADVDISK.EXE to your boot drive (C:) and add this line to CONFIG.SYS:
DEVICE = C:\ADVDISK.EXE
Command-line options
--------------------
ADVDISK is actually two components, the resident driver (installed in
CONFIG.SYS) and the executable (run from the DOS command-line). Each
component has it's own set of command-line options.
The resident driver recognizes these options:
/P
The driver will pause after loading.
/X=h,i
ADVDISK will, by default, attempt to use all fixed, removable, and
magneto-optical disk drives it finds on the SCSI bus. If a particular
device is being used by another driver, add this exclude option to the
command-line, and ADVDISK will not control the device. For example:
DEVICE = C:\ADVDISK.EXE /X=0,3
will exclude the device on host 0 with device ID 3 from control.
/R=n
ADVDISK will only reserve one drive letter for each REMOVABLE device.
Under most circumstances, this is sufficient. However, if the media used
by this device has more than one partition on it, ADVDISK will need to
reserve more drive letters for each device. For example, if using media
with two partitions use:
DEVICE = C:\ADVDISK.EXE /R=2
If ADVDISK does not detect as many partitions on the media as specified
to reserve, it will report "drive not ready" for the undefined partitions.
The executable component of ADVDISK has it's own set of command-line
options.
/? or /H
Displays a usage screen detailing all the command-line options available.
MAP
ADVDISK will display a map, showing which SCSI devices are associated
with DOS drive letters, and their lock status.
LOCK [drive: | ALL]
This will lock a particular drive (or all ADVDISK drives) into place.
Media must be present in the drive for this command to be successful.
Once the drive is locked, the media can not be ejected from the drive
using the eject button. This is only applicable for removable devices.
UNLOCK [drive: | ALL]
This command will unlock the particular drive, and allow for the media
to eject normally. This is only applicable for removable devices.
EJECT [drive: | ALL]
The media will be ejected from the drive. If the drive is locked, this
command will unlock the drive and then eject the disk. This is only
applicable for removable devices.
PARTITION
ADVDISK has a simple disk partition program built-in. This program should
be used for any unpartitioned media you wish to use with ADVDISK.
The program will ask in an interactive manner which drive is to be
partitioned. ADVDISK will not generate more than one partition on the
media, and will not selectively remove partitions. It will re-partition
disks simply by overwriting the old partition.
PARTITION will completely wipe out any information already on the media
and therefore should be used with care. It will ask for confirmation
before partitioning the media.
Using ADVDISK with real-time disk compression
---------------------------------------------
Testing has not demonstrated any compatability problems with ADVDISK
and real-time disk compression, such as Stacker, DoubleSpace, or
DriveSpace. However, these utilities will swap drive letters to
make the compressed drive seem to exist where the uncompressed used
to reside. This can confuse ADVDISK's locking and status reporting
features.
To use these features, specify the drive letter that corresponds to the
uncompressed drive when working with ADVDISK.
