I have never pulled an IC with power on. Now I see a whole bunch of posts about this resolving a bad cmos flash situation.
I have a Soyo with a bad flash, so nothing will boot. People say that you need to just get a good cmos, remove the bad cmos and hold the good chip on the socket so that a dos floppy will boot. Then they say to take the good chip off (with power still on) and install the bad chip. At that point you can try to reflash the bad one.
Anyone try to play with the flash cmos under power?
It sure does not seem safe to me! I have a new chip coming, but would sure like to "fix" the bad one as a backup!
Sure would be worth a few $$$ for MoBo's to have a ROM...enabled by jumper...that would allow you to boot a floppy, remove jumper, and then reflash cmos!
