I tried something like that once... (assuming your "mem=3D32" is literally
what you tried and you didn't miss something in transcribing to mail...)
mem=3D32 literally means 32 **bytes** of memory... Try mem=3D32m - it'll pr=
obably
be more like what you intended...
from /usr/src/linux/arch/i386/kernel/setup.c (starting at line 308 in 2.2.1=
2):
/*
* "mem=3Dnopentium" disables the 4MB page tables.
* "mem=3DXXX[kKmM]" overrides the BIOS-reported
* memory size
*/
....
....
