Thinkpads Forum

I have come into possession of an L7400 C2D systemboard for an X60s,
and have subsequently learned that I shall be unable to access 4GB
of memory on it because of issues involving the brain-dead Intel 945 chipset
and the stock Lenovo BIOS. Dell apparently worked around this problem,
but Lenovo apparently never bothered.

Does anyone out there know of a modified BIOS which would enable
me to access 4GB of memory with a 64-bit operating system?

Welcome to the forum!

AFAIK, such a BIOS doesn't exist for any of the ThinkPads with the given chipset.

I've promised the X60s to a needy soul, and have
purchased an X61s from a popular auction site.

Someday, I may run into the guilty parties that
designed the 945 chipset, and let them know
how I feel. I'll bet that there was a lot of
finger pointing at the time.
