>From bitter experience, I learned to watch for BIOS's that grab the
top 4k of RAM for themselves. That's not a problem if Linux uses the
value reported by the BIOS itself, but if you start sticking append
lines specifying "mem=xxM" then watch out !!!
I now have 128M of RAM on my machine, but if I specify "mem=128M" then
it locks solid EVERY time for precicely this reason. However, if I
specify "mem=131068k" instead, thus reducing the amount of memory by
just 4k, I get NO problems whatsoever...
