This is the 046 BIOS for the Tomahawk motherboard
Before installing this update enter the BIOS setup and look at the current version. If you see BIOS version 0AAGTxxx where xxx is less than 046 then this is the right BIOS for you. Allows HDD up to 32GB, I didn't try bigger.
Gateway part no. for mainboard is 4000271
Also refered to as Intel Pentium LPX motherboard although I couldn't find these part no.s anywhere on the board.
