What sort of difference, byte-wise, should there be between an unmodified BIOS and one patched with SLIC 2.1? I wrote a simple C program to compare two unpatched/patched BIOSes for my motherboard and it was ~85-95 kB. Does this sound about right? Forgive my paranoia, but the whole reason I went with a BIOS mod instead of a loader is because rootkits scare the bejeezus out of me. I probably wouldn't be so nervous if McAfee's corporate version AV's overzealous heuristics didn't almost invariably pick something up.
