Hi, guys!
The situation is: I'm getting the infamous message of "Fatal Trap 12 -
Page fault while in kernel mode" while I am trying to install FreeBSD
5.4 (and that also happened then I was trying to install 5.3 to the
same machine before, I don't remember how I solved it) to an IBM
Pentium 100 machine, 32 RAM. This box has no support for CDROM boot,
then I have made the three boot floppies from the 5.4 floppies on
FreeBSD ftp.
I downloaded the archives (I'm at a Linux Slack 10.1 now), then:
#dd if=3Dboot.flp of=3D/dev/fd0
And did it with the two another files. Ok, then I booted the machine
with the boot floppy, then kern1.flp, kern2.flp, and then boot.flp
again. No matter what option I choose on FreeBSD boot menu (the one
with the ASCII daemon), I get the following Trap 12:
------------------------------------
(Last line from dmesg before trap 12)

Uptime 1s
Automatic reboot in 12 seconds - press a key on the console to abort
---------------------
What should I do? Thank you in advance!
