I can attest to this. I've got a PVI-486SP3, with the SiS 496/497 chipset and a Cyrix 5x86-120 chip. I'm running 2.1.0-RELEASE off of a SCSI drive on an Adaptec 1542CF. As most of you probably know, this is a bus mastering card, and I have run into quite a few problems when running at 120 MHz. However, at 100 MHz everything is ok. There's 16k of write-back L1 cache, and 256k of write-back L2 cache. I have heard from quite a few other folks that they have problems too, particularly with this motherboard, CPU's that use write-back L1 cache, and Adaptec SCSI cards (1542C, 284x, 294x). One person was using a BusLogic card, but he switched to a different BusLogic, and everything was ok. Wish I'd known before I got it (too late now). Carlos -- Carlos A.
