Bios Mods -The Best BIOS Update and Modification Source

Hi, I was wondering if someone could help me with modifying my current BIOS to support larger HDDs. I currently have no supported HDDs, so I can't install Windows 98SE like I wanted to.

Attached, is my current BIOS. Any help would be amazing.

Can someone at least point me in the right direction to do it myself?

is your bios an original or an update of the original bios ?
what is the date of this bios ? the date of the original bios is 1997.

I have tested it and is bios evaluation rom not for sale.
