(I found no sign of the MPC55 using FWH, it seems to be LPC only. Clarified the sentence.)

There are 4 volume revisions, 2 with plcc32 (v1.0, v1.1) ([http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2287&ModelName=GA-M57SLI-S4 soldered BIOS]) and another 2 with single 8 pin SPI. All 4 have unpopulated secondary pads, which can be utilized (see below).

The fact that the BIOS is soldered onto the board complicates matters considerably, because it means that one flash of a faulty image will render your board unusable (it will be 'bricked'). [[Top Hat Flash]] does not work with an SST 49LF040B 33-4C-NHE soldered onto the M57, but might work with other chips.

It is possible to desolder the BIOS chip, and replace it with a PLCC socket. You will need some tools (heat gun/pencil, good soldering iron, etc) and soldering experience to do that. The other option is to add a PLCC socket to the empty position next to the soldered-on BIOS chip. With an extra resistor and a switch, this allows switching between 2 BIOS chips. This has been documented carefully by ST; see his [http://private.vlsi.informatik.tu-darmstadt.de/st/instructions.html instructions].
