To minimize CPU usage I'd prefer SCSI HDDs. Anything from 2 to 8 GB should be fine.

Yes, the 274x does have native support in Windows 95 and Windows 98. Perhaps I will put my GUS classic 2.2 into this computer. Since the drivers do not work under 98, I'll stay with Win95C then. I can find a v2.10 BIOS on the Adaptec website. My adapter has v2.11 already. Because the mainboard BIOS …

Try to put a multimeter between the battery and the board. Tell us how many milliamperes your board draws from the battery. It should be a few microamperes.

When you get a bundle of hard discs and do a kind of triage by connecting the drive only to a PSU you may draw the wrong conclusion (false-negative).

This is true but only delays the spin for a few seconds, The controller has to wait for an extra moment for the drive to spin up so it can then initialize it. It was so the PSU wasn't overloaded with multiple disks all drawing power at the exact same time, not as a power saving feature. But if …

OLB is similar to VLB but not widespread. I've seen some pictures of ET4000AX on OLB, but no W32's. We've got a Tekram cache controller for OLB, but no graphics card. Compared to the VL version it has more discrete parts on it. However, the controller uses low speed PIO to communicate with the HDD, …
