The point is, I already have the source code and I'm willing to know it's "award versioning system". You can read my findings (this is slightly reduced version of the guide I already uploaded to the FTP) at _http://www.geocities.com/mamanzip/Articles/Award_Bios_RE/Award_Bios_RE_guide.html. This is my level of understanding right now. I'm quite sure there's a "missing" version between the two award bios source code I have (between 1998 and the 1999 source code) right now and I'm keen to have it . I know that I even have the source code for the different chipset than the one used in my mainboard, but that doesn't really matter. Here's a quick hint: why my BIOS uses the majority of 1998 source code but uses the 1999 LZH decompression engine in the bootblock ?
