BIOS Patcher is a kind of software that can find and fix errors in your system BIOS and also it can add or open new features, i.e. some features that your BIOS has but they are closed by manufacturer of your motherboard. WHAT DOES IT MAKE? BIOS Patcher scans rom file. If it finds any known errors it fixes the errors. If it finds any closed features it opens it. Also if it is started with any keys for add new features than it should add it. HOW DOES IT WORK? As we know AWARD BIOS consists of several LHA-packed parts. For scan patcher extracts parts that it needs into RAM and looks for parts of code that it knows and that contains errors. If it finds something looks like an error it should check this error by several other signals and if all is allright patcher will signalize about it. If patcher has some mishmash about this error it shouldn't fix it. WHY DOES IT WORK? It is rather big question. I'll try to tell about shortly. Programmers who writes AWARD Bios sells it to motherboard manufacturers, who can change and/or add new features. It seems clear that nobody will write BIOS from the very beginning (Simple not every company has their own programmers and money for them :-)) That's why BIOSes of most motherboards looks like others. That is why all that motherboards has seldom updates of their BIOSes. And that's why most of them has identical errors and that's why patcher works more effective with this BIOSes.
