With mem=X option the kernel ignores what lilo has detected and
forcibly use this much memory. Try this option with more memory than what
you have, linux crashes when it starts using invalid memory. You can
even give mem=4M to simulate a low-memory device.
You can try progressively reducing the number by few meg, (like mem=125M)
and get around the buggy RAM chips. Maybe that this motherboard uses
some part of the RAM for its on-board chips ?
(on one i810, bios reported 97M+1M: linux 2.2 uses 64M by default,
crashes with anything more than mem=95M, linux 2.4 probes bios instead
of lilo and reports 94000k/97280k )
