BX supports 256MB PER SLOT, not 256MB total. Most boards came with 3 slots (768MB), some came with 4 (1GB), etc. The max density supported is 16MB per chip, so that a 256MB module needs to be 16 chips, 8 per side.

Your board is compatable with USB 2.0 devices already, but will use them at USB 1.0 speed. BIOS can't fix that, it's the hardware. USB 2.0 has always been backward compatable to slower speed controlers.

Your board is compatable with ATA133 devices, but will run then at ATA33 speed. BIOS can't help that either, it's the limit of hardware. ATA133 has always been backward compatable to slower speed controllers.

So it looks like this "BIOS Upgrade" gives you the compatability you already have, with no additional features!

Crucial has a compatable PC133 256MB Cas2 part number CT32M64S4D7E for $32 with free 2 day shipping. Too bad you only have 2 slots.
