Hi all,
I'm trying to install FreeBSD 4.8-RC2 (just because it happens to be the
latest version of FreeBSD that I have a CD for) on a second-hand PC.
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

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
