I have an A2000 with a GVP 030 at 40mhz and a scsi2 controller. 540mb conord HDD and an 8UP! with 4mb
4mb on the accelorator card = total 9mb 3.1 roms
and i have had ZERO PROBLEMS with the install! might be the CD or check the connections to the cd-rom and HDD.
since you have the original disk I would be more than happy to burn my original and mail you the "back up" disk
:-D
