    This is a vintage 2000/2001 P3 laptop. It has 64 MB on the motherboard and one PC100 DIMM slot. The specs from Compaq claim it can take a total of 320 RAM which would mean a 256 DIMM in that slot. But when I put a 256 DIMM in there it will only recognize 128 of it for a total of 192. I've got the latest BIOS which was last updated in 2001. There is nothing in the BIOS settings that relates to memory.

    Any ideas? I vaguely recall an issue I had with a desktop machine of that era where it would only recognize half the memory on a DIMM because the DIMM had higher density memory chips on it or something like that.
