Hi,
For some reason the Squirrel Installation software places the CD ROM DosDriver into your Storage/DosDrivers Drawer.
Check to make sure its there and if so copy it to Workbench/Devs/DosDrivers.
I have the following set up which runs on either a PhaseIV Blizzard/030/50 or a PhaseIV Blizzard060/50 A1200.
Workbench ver 3.9 BB1
Workbench:L/CacheCDFS (ver113.19)
Workbench: Squirrel/Devs/SquirrelSCSI/SCSIMounter (ver 2.04)
Devs/squirrelscsi.device (ver37.775)
Devs/DosDrivers CD0 (ver40.6)
Tooltypes in CD0 Icon
ACTIVATE=1
DEVICE=squirrelscsi.device
UNIT=3
DONOTWAIT
Check your CD Icon ToolTypes are set correctly, and ensure you have a CD ROM Disk in the drive when you run SCSIMounter.
Also, check you have the correct SCSI UNIT ID number on the device set, mine is set to ID 3 as in the CD Icon Tooltype.
If you want I can send you the files for you to install and tweak.
