It's a hack of a BIOS savior using one FlashROM, no PCB, just a switch and 
three
wires. I don't know what the BIOS saviour is doing exactly, but generally 
you could
wire two identical FlashROMs in parallel (except the /CE signal). Then you 
connect
the /CE signal coming from the Mainboard to the switch. The other two pins 
of the
switch are connected to the /CE signal of the two FlashROMs. That's all...

Disadvantage: You'll need a 32pin PLCC-Plugin-Adapter (I don't know the 
right name)!
