Chapter D - Using Microsoft MS-DOS
H: host adapter number
I: SCSI ID of the SCSI device to be reserved
x1, y1: host adapter number, SCSI ID
of the first SCSI device to be reserved
(in decimal form)
x2, y2: host adapter number, SCSI ID
of the second SCSI device to be reserved
(in decimal form)
Example: We assume that there is only one GDT controller in the system. Two direct access
devices, the SyQuest removable hard disk connected to channel A, ID 2, and the Quantum
hard disk connected to channel B, ID 4, have to be reserved for the ASPI manager. The co r-
responding entry in the CONFIG.SYS is:
DEVICE=GDTASPI.EXE /R:H0I2:H1I4
Important note: SCSI devices reserved for the ASPI manager must not have been initialized
with GDTSETUP. Neither must they pertain to a GDT cache or host drive. If necessary, these
devices can be de-initialized with GDTSETUP.
As already mentioned in paragraph 6 of this chapter, in addition to the ASPI manager an
ASPI module has to be present in order to be able to access the SCSI device under MS-DOS
with a drive name (e.g. D, E, ecc.). Following you find how to install ASPI interface-reserved
direct access devices with the ASW ASPI module ASPIDISK.SYS (from Adaptec) and the corel-
SCSI ASPI module UNI_ASP.SYS (from Corel).
D.9.1 Using ASW ASPIDISK.SYS
Step 1
:
Include GDTX0000.EXE, GDTASPI.EXE with appropriate reservations (../R:..), and
ASPIDISK.SYS in the CONFIG.SYS file, then do a warm reboot (Ctrl+Alt+Del).
Step 2
:
Use the ASW program AFDISK.EXE to initialize the drive to be run through the ASPI
interface.
Step 3:
After the successful initialization, do a warm reboot (Ctrl+Alt+Del).
The CONFIG.SYS will be similar to the following (the relevant entries are printed bold):
device=gdtx000.exe
files=30
buffers=30
stacks=9,256
shell=\COMMAND.COM /E:512 /P
device=\gdt\gdtxdos.exe
device=\gdt\gdtaspi.exe /R:H1I4
device=aspidisk.sys
Note: drives run with ASPIDISK.SYS are not compatible with drives run with GDTSETUP.
D.9.2 Using corelSCSI
Step 1
:
Include GDTX0000.EXE, GDTASPI.EXE with appropriate reservations (../R:..) in the
CONFIG.SYS file, then do a warm reboot (Ctrl+Alt+Del).
Step 2
:
Load corels Install program and follow the instructions. Preferably, use Express-Setup.
Step 3
:
After the successful installation, do a warm reboot (Ctrl+Alt+Del).
Step 4
:
Using the corelSCSI program CFORMAT, format the drive to be run through the
ASPI interface.
