Bios Mods -The Best BIOS Update and Modification Source

Hi all,

I have a very old IBM ThinkPad Z60m (almost 11 yrs old) and I wish to use a 3rd party wireless card. Therefore, a modified bios is needed. I have conducted a thorough and careful search both online and in this forum, but nothing useful is revealed. A previous solution in this forum is not accessible as the file is deleted by the online storage service provider. Please help me out with this bios modification.

The laptop comes with an Intel 2915ABG wifi card.
The PCI ID is like this: PCI\VEN_8086&DEV_4224&SUBSYS_10128086&REV_05
The original bios is as follows:

Thanks!

I have updated some relevant information into the thread according to the requirements. Could anyone help me out with it?
