I need some help please with Lenovo BIOS

Hi there, I have a request for a modded BIOS for my Lenovo machine. It is an older type and I wanted to know if anyone here would be able to modify it to update the latest Intel microcode as at present it is only able to use a 2.4ghz older style CPU and I would like to add a much bigger one. The machine has the ability to run a 1066mhz bus and there are much better CPU’s than the E6 series. any help would be appreciated.

Manufacturer : IBM
Model : M55-8813-B44
Bios Revision : 2KT49
Bios Link : http://download.lenovo.com/ibmdl/pub/pc/…jj949a.iso
Bios Type : Phoenix
CPU Socket: 775

One thing I did notice, a lot of sites, including this one, refer to .bin files but, all I could find so far is a .img file out of the bios.iso from Lenovo
and I can’t figure out how to extract a .bin file from this. ANY help would be really appreciated.

@ Pendaws:
Welcome at Win-RAID Forum!

Generally this Forum only offers guides about how to update PCI ROM and MicroCode modules, which natively are within the original BIOS.
The support of natively not supported CPUs requires a modification of system BIOS components. I cannot help you, because I don’t have any experience with this sort of BIOS modding.

The links to your BIOS did not work for me (maybe because I am not a LENOVO customer).


Thanks for letting me know. I will have to research other avenues. :slight_smile:
