/etc/lilo.conf, note the append= line, just add the mem=nopentium to it
as follows,
image=/boot/vmlinuz-2.4.18-6mdk
label=82-2.4.18-6
root=/dev/hda7
initrd=/boot/initrd-2.4.18-6mdk.img
append="devfs=mount hdd=ide-scsi hdc=ide-scsi nobiospnp mem=nopentium"
vga=791
read-only
don't worry about the extras Ihave,
John
