On this page, I will show you some modifications I have made to my PC's BIOS...

First, let me show you the original BIOS contents...

There are 5 major differences.
I suggest that if your computer has a boot block, when you flash any custom BIOS, use the /Sb option in AWDFLASH.. This skips programming of the BootBlock, therefore no matter how screwed up your custom BIOS is, it SHOULDN'T ruin your BootBlock recovery method. (At least that is what I hope when I do my modifications ;-))

Anyway, here are the 4 differences:
1) VGA ROM. In the original BIOS, the SiS 530 AGP BIOS is v1.02.02. I have scoured the web for Award bios based systems that use the SiS 5595/530 chipset by various manufactures (like ASUSTek, ABIT, ect) and extracted the VGA BIOS (using CBROM) from them, and the highest I found was the one I am currently using, v1.08.01.
2) Flash ROM. I don't have any idea what the point of putting AWDFLASH.EXE in your BIOS has, but it was an option in CBROM, and maybe it has some purpose I don't know of? It is the first thing I remove when I need more ROM space.
3) EPA LOGO. Of course I was going to customize the Energy Star logo.
4) Logo BitMap. I wanted a full screen boot logo, but apparently my BIOS does not support such, because it ignores it, as if there isn't even one in the ROM.
5) MODBIN Edit. The modbin edited BIOS is a different file from the first Altimit BIOS, and includes string edits, and a few hidden BIOS options enabled, and CMOS Setup Defaults customized to my PC. The MODBIN edit requires Award Flash v8.12, and after some troubles flashing, I realized the importantance of adding Award Flash v7.01 into the System ROM.

Anyway, below are some pictures of the EPA, old and new.

As soon as I have a good way to capture the POST, I will put up a shot of it.

[ About EP-PS21 Motherboard ] - Note: This is not the EP-PS21, but the board specifications, layout, design, ect are the same. The only difference is the EP-PS21 came in a computer bundle, with CPU, Hard Drive, ect, and the BB-PS21 is sold as a Bare-Bone system.

That is all for now, more will be added when available. :-)
