No problem!  I've got a 486/25sx running as our web/ftp/whatever server
for ResNet and it rocks right along. :)

Okay, your problem is that you've installed your kernel over the 1024
cylinder BIOS limit.  Many older PC BIOSs can't boot anything that exceeds
1024 cylinders, approxmiately 500mb.  The entire root partition must land
within this 500mb limit.  After that, things can be anywhere.

There are a few ways to rememdy this:

1.  Move your FreeBSD slice forward in the drive.  If you have DOS on this
disk, make an extended partition at the end of the disk and put your data
there, since you won't need to be booting that.  Make a small primary
partition to hold the OS.  Put your FreeBSD slice in the middle and you
should be okay.

2.  If you can figure out how to do it, you can make two FreeBSD slices,
one below the limit which holds root and the rest which holds the rest of
the system data.  This requires some manual tweaking and I'm not sure how
to do it using sysinstall.

If I could see a map of your drive, I could get a better idea of how far
you're off.
