I really doubt you'll get to a Gig with that setup, but here it is:
step1: set your bios setting to default - remember the cpu speed too.
step2 : set voltage to user defined, set to highest available setting.
step3: save settings and restart.
insert the ss bios disk.
now the computer will start from the floppy.
1: type awdflash and flash program starts.
2: type in the name of the .bin file (bh6_ss.bin)
3: the flash program will ask you if you want to save the old bios - answer yes!
4: save the old bios to floppy with any name you like . press enter.
5: after the flash program has saved the old bios it will ask you if you want to program the bios - answer no.
6: the flash program will now terminate and return to your floppy drive.
now you are ready to trick your bios voltage settings!
7: the trick is not to start the flash program as you did previously .
8: type exactly as follows for the bh6ss bios : awdflash.exe bh6_ss.bin /py /sn /cc
9: press enter and later f10 to exit program.
10: restart and go into bios setting - now you will see the higher voltage is now the default.
Wish I could give credit to whoever posted this first, didn't make a note of their name.
