The computer's BIOS ("Award Modular BIOS 4.50PG") claims that it is a "6x86-P166+". I don't know the make of the motherboard (there are no obvious identifying marks that I could find on the portion that's visible with the case open.) It has a CD-ROM drive but it can't boot from it, so I'm booting from floppies. I'm pretty sure the floppies are good - diff'ing them against the disk images doesn't produce a 'binary files differ' message, and they boot up on another (more modern) computer just fine. The problem is this. I get the following message every time I try to install from floppies, after I've inserted the mfsroot disk and pressed Enter (a fraction of a second after the screen shimmers slightly.) The message is wholly consistent, never different from time to time: -------------------------------< snip >---------------------------- Booting [kernel]... - Fatal trap 12: page fault while in kernel mode fault virtual address = 0x4 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01e119e stack pointer = 0x10:0xc0843fe4 frame pointer = 0x10:0xc0843fe4 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = Idle interrupt mask = net tty bio cam trap number = 12 panic: page fault Uptime: 0s -------------------------------< snip >---------------------------- Possibly this whole endeavour is a waste of time, but I thought I'd ask here on the off chance someone knows why this happens and/or how to get around it. Thanks in advance, -Chris
