I'll try to take a quick look. Does it have a socketed bios part?
No, it (unfortunately) doesn't, it's a TSOP. However, I have another of the exact same board that, if necessary, the bios chip can be scavenged off and sodiered to the first board (the other board has a broken handle on the zif socket). Has anyone ever tried installing a switch for easy swapping back and forth between bios chips?
The simplest way would be to just piggyback all pins of chip 2, except /CE, onto chip 1, then lift chip 1 /CE from the mainboard and have a switch for selecting either chip 1 /CE or chip 2 /CE to connect to the mainboard, possibly with pull-up resistors on both chips. (ideally only the one not selected)
Beware that TSOP packages demand very skilled soldering.
