I tried something like that once... (assuming your "mem=32" is literally what you tried and you didn't miss something in transcribing to mail...)
mem=32 literally means 32 **bytes** of memory... Try mem=32m - it'll probably be more like what you intended...
from /usr/src/linux/arch/i386/kernel/setup.c (starting at line 308 in 2.2.12): /* * "mem=nopentium" disables the 4MB page tables. * "mem=XXX[kKmM]" overrides the BIOS-reported * memory size */ .... .... ....
