GA-m57SLI-S4 Dual Linux Bios DIY


This is a short instruction how to utilize the empty flashrom pads on a GA-m57SLI-S4 (rev. 1.0).

Please realize that nobody will take responsibility if the Motherboard seduces your grandmother or other nasty stuff happens.

Currently it is not known if the SuperIO Chip is connected to the INIT# pins (the ones where the cables 1 and 3 go). If yes the whole procedure may be harmfull to your mainboard even if you manage to solder successfully ;-)... but it works for me!
Andreas has the following suggestions:

Two things can perhaps be added to ST's instructions/wiki:

This is consistent with Ohm's law: I=U/R=3.3V/100kOhm=0.033mA for the added chip. It shows that the soldered chip is pulled up also with a 100kOhm resistor and no other chip should be damaged by that(?). Reading and writing works without problems on both chips.

After that you should take an multimeter and check that there is no short-circuit at the soldered pins.Pins 3 and 4 of the PLCC32 socket are shortened by the mainboard. Don't forget to put the flash-rom into the socket.

The result should look s.t. like this (switch not shown):
