143Chapter D - Using Microsoft MS-DOSH: host adapter numberI: SCSI ID of the SCSI device to be reservedx1, y1: host adapter number, SCSI IDof the first SCSI device to be reserved(in decimal form)x2, y2: host adapter number, SCSI IDof 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 accessdevices, the SyQuest removable hard disk connected to channel A, ID 2, and the Quantumhard 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:H1I4Important note: SCSI devices reserved for the ASPI manager must not have been initializedwith GDTSETUP. Neither must they pertain to a GDT cache or host drive. If necessary, thesedevices can be de-initialized with GDTSETUP.As already mentioned in paragraph 6 of this chapter, in addition to the ASPI manager anASPI module has to be present in order to be able to access the SCSI device under MS-DOSwith a drive name (e.g. D, E, ecc.). Following you find how to install ASPI interface-reserveddirect 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.SYSStep 1: Include GDTX0000.EXE, GDTASPI.EXE with appropriate reservations (../R:..), andASPIDISK.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 ASPIinterface.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.exefiles=30buffers=30stacks=9,256shell=\COMMAND.COM /E:512 /Pdevice=\gdt\gdtxdos.exedevice=\gdt\gdtaspi.exe /R:H1I4device=aspidisk.sysNote: drives run with ASPIDISK.SYS are not compatible with drives run with GDTSETUP.D.9.2 Using corelSCSIStep 1: Include GDTX0000.EXE, GDTASPI.EXE with appropriate reservations (../R:..) in theCONFIG.SYS file, then do a warm reboot (Ctrl+Alt+Del).Step 2: Load corelís 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 theASPI interface.
