I have the following problem: my laptop refuses to boot. When booting to Windows, it gets stuck at loading CLASSPNP.sys, on Linux its some ACPI error (dont have the exact logs atm, I can post them later if needed | it boots with failsafe mode enabled). The same goes for any Live-OS or Install disk which uses ACPI. After some digging I have found that the most probable source of this problem would be a broken / corrupted BIOS, so I wanted to update it (its fairly old as well). Long story short, since I cannot boot into Windows and American Megatrends doesnt offer their AFUWin / AFUDOS Software for linux, I created myself a FreeDOS USB Drive and tried to update the BIOS from DOS. Everything works as it should, except for the ever so slight issue that AFUDOS complains about a write-protected BIOS, then freezes and has to be hard-resetted. Since the laptop is some no-name brand and nowhere to be found on the internet and the mainboard turned out to be unidentifyable, even after opening the device, I am not even sure whether or not I am using the right tool at all... (BIOS is an American Megatrends one, Version 2.14.1219). I tried to locate the BIOS Chip and look it up, maybe I could short two pins and make it writable, but found myself unable to locate it at all.
What should I do? I'm really out of ideas now...
Thanks in advance, Tim
