Well, I've determined that everything works fine under ms-dog so it isn't the cable. :) However it still doesn't work under 386bsd. :( Would some kind soul with a 1542C tell me *exactly* how they have it set up? It was suggested that it may be a CPU cache problem but I first disabled the external, then the internal and it didn't have any effect. [For those who missed the original post, I've got a Adaptec 1542C and Quantum P105s (among others) that I'm trying to get working with 386bsd. I'm using the 0.2.3 patched GENERICISA kernel from agate. Disk i/o get terribly mangled most of the time. On two occasions I got a kernel panic (and die). I'm booting off an ide drive that works fine. The machine is a 486dx33 with 8 meg of ram and a 256k external cache and vl-bus. BIOS is AMI. According to the little booklet, the motherboard is a UM 486V AIO if that means anything to anyone.] -john -- === jfieber@sophia.smith.edu ================================================ ======================================= Come up and be a kite! --K.
