    Just an FYI, As of 04/09/08, Lenovo BIOS mod working just fine with SP1 and updates installed. Still looking for a "pro" translation of the process...

    I think I've understood the process, but to make it sure somebody should try a mod I've made.
    So what bios should I try?

    Thanks!

    It was a lot of fun to make an effort!
    I hope it is useful.

    The most confusing thing was the physical addresses. It took some time to get that PBE calculates them in a wrong way.

    PBE “thinks” they are all 1Mbyte bioses! Stupid!

    Another matter was that this bios was a 4 Mbyte bios, so there is another base address to use (FFC00000)

    The base address for a 1Mbyte bios is FFF00000

    The highest addressable range is FFFFFFFF. Bios is always ‘shadowed’

    So the base address (lowest) is always: FFFFFFFF minus size of bios + 1!
    4MByte = 00400000h. (0 to 3FFFFF)


    Enjoy!
