I haven't heard anything back on this, so I thought I'd send an update. I'm pretty sure that the problem is that the motherboard in this machine is complete junk. I've disabled the internal and external caches, and have done just about every CMOS config trick I know to get this to work. The closest I've come is that I can get the cpio disk installed, it then pukes when loading instdist (I think). It gets a trap 12 and reboots. Any ideas? Or should I scrap this MB and scrounge another?
