Or it could be that your storage device only speaks LBA and your motherboard only speaks CHS. It would be interesting if you could put an XTide ( or some other LBA aware) option rom in your system and see if it detects then.

Why two screw types in PC cases?

Anyone know the story behind why PC cases ended up with some #6-32 UNC screws and some M3 screws ? I'm working on a case that takes M3 screws for the rear expansion slot covers and I'd like to think about the story every time I grab the wrong screw.

Thanks. I assume we both used hdds / CFs With muuuuch more capabilties than any PIO mode. One add-on: according to this page: https://forum.vcfed.org/index.php?threads/isa-maximum-sustained-transfer-rate.57260/ The cpu speed will make a difference as higher clock speeds will reduce I/O cycle times …

Agree. Regarding the last bullet: again that’s why I wonder why with double isa clock (25MHz) you only get 4000kb instead of my 3500kb with 13 MHz clock. Maybe we run into the pio 0/1 limit instead of isa limit. Or is this bypassed by XTIDE? With PIO over ISA, the IDE device frequency is hardwired …

Also surprised that you could bench your scsi drives with speedsys. Mine wasn’t detected there no matter what config (in bios, aspi driver y/n, etc). It simpl wasn’t selectable. Same for nusi8 and others. 4speed was the only one. My experience with caching IDE controllers & SCSI controllers is that …

@douglar If your question was towards me - no software drivers needed for all ISA SCSI controllers i touched so far, including the AHA-1542 noted above. The original poster was doing tests under windows 95, so I figured a SCSI driver was involved. p.s. If you are testing under DOS&BIOS, I guess the …

So basically, it never did anyone any good being an AGP4x, 8x, PCIe early adopter. 4 lanes were probably good enough until 2012ish, 8 lanes probably only started to fall noticeably behind 5 years ago, and are probably fine on a lower-mid card still... and funnily enough they still don't sell $5 …

This is wrong. Neither the GeForce 2 MX-400 and even less so the TNT2 saturate AGP 2x's bandwidth. AGP 4x does nothing for these chips. Even if it did, it is likely that the K6-2+ doesn't have enough juice to drive them. AGP bandwidth has been discussed multiple times in the past, AGP 8x wasn't …
