It's not a BIOS problem, it's a garbage memory problem. You see, it's cheaper to use 4 "high density" chips than 8 standard density chips. The new definition for "high density" exceeds the compatability of 90% or more of the SDRAM boards on the market. When a chip is sold that's only compatable with 10% of the boards it's made for, it's garbage even if it's not defective.
What to do? Get a module with at least 8 chips on it. Better yet, get one with 16-chips so it will be cross compatable with even more boards! Crucial carries a very nice 256MB module (PC133 Cas2) as part number CT32M64S4D7E, it's only $32 including 2 day shipping.
