Bios Question

Post by ellison » October 16th, 2016, 8:03 am

I can't find any information about the BIOS, really. I just want to know if it is *nix related. I guess we'll find out in 2038.

Thanks, Shadow. Can you point me in the right direction for some more reading material on the BIOS?

What reading material exactly? The BIOS isn't open source. The only material available is anything Google has indexed from crackers and hackers messing with the BIOS via disassembly.

Seems that way. I was just fishing for more leads on my BIOS retexture fantasy.
