I'm having some problems with a new FreeBSD server-type machine. I've
installed from the 2.1.5-R CD. I'm not new to Unix, but I have very
little experience with the joys of braindead PC hardware. (I'm used to
SPARC- and MIPS-based workstations.)

When attempting to build a kernel, (even GENERIC), it will usually
terminate with bus error. Occasionally, it'll report a segmentation
violation. Occasionally, it will compile, but it seems that as soon as
it barfs on a compile, it won't be able to build anything until after
boot time.

I'm hoping that someone will be able to point me in the right
direction of things to do in order to figure out what's going on.

Here's the hardware:
    133MHz Genuine Intel CPU
    Pentium motherboard, triton chipset, stupid AWARD BIOS
    64MB (two 32MB EDO (8x32) 72PIN SIMMs)
    256k VGA ISA video board
    3.5" floppy
    Conner 2.1GB SCSI HDD (CP2105S)
    Adaptec 2940W Wide SCSI controller
    IDE internal CD-ROM
    two Intel EtherExpress Pro network cards

The first install that I did with it had the incorrect boot drive
geometry, which caused some strange problems, as you might imagine ;-)
Anyway, that is fixed, and the bus errors during linking seems to be
the only problem that I'm having.

I've installed the OS right on top of the drive (i.e., not as a
partition on the drive).

I think that covers everything relevant... Hints?
