Hello! I'm doing a firmware patch on my iBook G4 (it's an 800MHz board with a 7445), using the Giga Devices patch, I do everything as it should then when it reboots after the tone it gives me "Boot-ROM Flash is off", anyone have any ideas as to how to fix this? I tried the uninstall option and...
We figured it out.
R49 and R48 are in parallel and then R47 is in series with it. This makes up R2 on the formula for the vCore...
vCore = 1.23 * (1 + 10k/R2)
These here
Just copied from my TinkerDifferent post :p
Shout out to @Bolle for the help over in the TinkerDifferent Discord, and...
@3lectr1cPPC @Byrd I got the Mainstreet card in and it had a 750 instead of a 740! So I soldered a 750S on, and am overclocking it. The IBM PPC documents for what I installed say 2.0V or so, the Motorola ones (what was on there) is 2.6V.
Hello! I'm looking for any documents which will give me the needed information to adjust the vCore on my PowerBook G3, I replaced the CPU and it chimes, but the vCore is far too high for the CPU and I need to turn it down. Any help would be appreciated!
It's a Wallstreet BTW, but my guess is...
The chip appears to be a AM79C950
Wikipedia says this is used through the ANS and PM9500 as well, and it is a combined SCSI, serial, and network controller
