I have used this process to install 3 Tualatin CPU microcodes (06B0, 06B1 and 06B4). I've also modified the BIOS revision number of the BIOS together with the BIOS dates.
I have not yet managed to get the BIOS to correct this. This may have something to do with the 'STRINGS0.ROM ' binary file or not.
Which files did you modify to get your bios to support those CPUs? I have a Presario 900 notebook and I'm trying to get it to properly support a mobile 2600 processor. The notebook is designed to top out at 2000, and it will see a 2600, but as an "Unknown CPU", and all the PowerNow management features are gone. I was thinking of plucking code from a bios that does support that processor and splicing it into my bios.
...Plus I want to change the bios logo while I'm at it, which seems to be the easy part.
I have a decent idea of what I'm doing, but since I only get one shot at this (with the results being a toasted mobo) I'd prefer to double check with someone who has been successful.
Also, with regards to the strings file, that's a good thought, but I don't think it's as easy as that. My bios doesn't have string entries for anything above 2000, and although I could add them, it'd likely screw up the order of those strings since I'm thinking that they're accessed by line number.
