I'm trying to understand what portions of an Award BIOS typically get modified and how. In looking at a file compare of a few different BIOS mods I notice, that typically about 1000 bytes have been changed in one big chunk and at least a two byte change is made in another place. From the tutorials I think I understand, that the SLIC table somehow gets appended to the ACPI portion of the BIOS using one of a few different methods. Could someone who is regularly making these mods explain, what exactly goes into those ca. 1000 Bytes? Apart from the SLIC table, does the mod contain any executable code? Is there an 'open source' documented mod available, that one could learn from? (Well maybe, its all been written somewhere else, if so please provide a link.)
