Strange issues with PC Compatibility card
Posted by: quinterro on 2009-04-30 05:53:30
I have a Beige G3/400 with 128MB RAM, a 9GB SCSI hard disk and a 3GB IDE hard disk. It also has a PC Compatibility card (Pentium 166) with 80MB RAM (16MB built-in + 64MB DIMM), a Voodoo2 and a USB 1.1 card.

The weirdness started when trying to make a hard disk image file. When I created one on the 9GB drive and tried to initialize the drive the Mac would freeze, requiring me to press the power button or pull the plug. When I made the image file on the IDE drive it worked just fine.

The strangeness continues when trying to format the drive under DR-DOS. When trying to format the drive, the PC locks at 2% of completion. If you do a quick format it locks at about 83%. Using FDISK to wipe the drive and verify its contents locks at sector 5000 of 63000.

I'm beginning to think it is caused by DR-DOS. I'll try with MS-DOS to see if it gets any farther along.

Any ideas as to why it is behaving so strangely?

Check both drives for bad sectors. How big are you making those virtual drives?

It is currently set for 1023MB. Both drives are formatted as HFS Extended.

Could possibly be an OS issue (I think this card came out when OS 7.5.3 was current and HFS was normal). Did you go to Apples website and download the latest software for that setup? I think I run mine under OS 7.6.1 (same card, Powermac 7500). It might not like anything past OS 8.1.

I downloaded PCSetup 1.6.4, then updated it to 2.1.7. I think the oldest MacOS that will run on the beastie is 8.

A beige G3 is 8.1 and above isn't it?

You're probably right. I have an 8.1 CD, but not one for plain old 8.

I use FreeDOS for my DOS software like GEM.
