BIOS Updates
I don't have all the info on which one of these BIOS updates works for which versions of the MP-975, so use at your own risk.
MP-975s with 256KB and 512KB of L2 Cache use different BIOS ROMs. In addition to this, Chicony lists separate updates for "notebook w/out docking station" and "notebook with docking station". I believe this has to do with the type of docking connector that your MP-975 uses. There were two versions, and I believe the earlier one with less pins only works with a port replicator. Based on this, if you have the earlier connector, you should use the "w/out docking station" BIOS. Still, this is unconfirmed, so flash at your own risk.
You will also need the BIOS FLASH.EXE program that it in the utility.zip download above.
Earlier connector type (MP-975A?)
Later connector type (MP-975D?)
