Hey guys.
I wanted to play with my BIOS and used ch341a and a clip to do it.
The clip corrupted the BIOS and the computer wouldn’t boot.
I unsoldered the chip, put it on the programmer board and read it but it was completely empty (all zeros). Found a dump online, flashed it and the computer boots (backlight as well). Before putting in my HDD, It would be nice if someone can take a look and see if the dump is clean. I know I’m being paranoid but better safe than sorry. I would do it myself but I’m not knowledgeable enough. Or you can tell me how to copy personal data to stock BIOS.
Thx in advance!
Both BIOSes (dump and official) are here: https://file.io/eQHLTYiOFxe0
Here it is again, hope it doesn’t get deleted from here as well.
I did an HxD comparison and it looks like the only thing different is the NVRAM (according to UEFITool) as one would expect. Whether everything there is fine I’m not sure
NVRAM can be deleted / replaced with the one from stock, will get rebuilt.
Machine specific data are at 0x10000 to 0x13FFF, but for a machine this old it doesn’t matter. Machine should boot fine with a stock Asus firmware (0x800 capsule in the beginning removed)
Sorry for the late reply, I was busy.
I’ve copied the machine specific data to factory BIOS, put it on the chip and managed to boot without problems. Without machine specific data backlight doesn’t work (I guess there’s some check after all). Now I want to dump the BIOS to see what NVRAM values have been repopulated but FPT says “Cannot be run on the current platform”, and flashrom says “Do not use flashrom on laptops (yet)!”.
What software option should I use?
