Flashing the BIOS?

[Don]

[SOLVED] O.K., I'm stumped. How does one flash the BIOSs on a Linux machine? I have a Lenovo X220, running Kubuntu 12.04x64. The only stuff I can find for flashing the BIOS is for Windows systems. I have a Windows VM, but I don't think that counts.
Many thanks.

Need to look into the documentation of the maker of that motherboard. (For Intel, for example, there's iso or CD methods for Linux, easily performed.)

It depends a lot on what the manufacturer provides for this. Often they only provide a Windows executable that creates a boot disk that contains the flashing tool or flashs it from within Windows. Many provide just the flashing tool, which you can copy over to a flash drive that has FreeDOS installed on it. You'll need to dust off some DOS command foo to start the program

Thanks for getting back so quickly. After a lot of searching (Lenovo doesn't make it easy), I discovered that the mobo is IBM-04w0702, but I am unable to find any BIOS updates for it. IBM won't let one in unless one is an IBM customer, and Lenovo appears not to count. More ideas?

I should say that the underlying problem is that I'm running Vmware and want to put a Windows 7x64 box on it, but my Lenovo keeps telling me that x64 won't work on the machine. "Binary translation is incompatible with long mode on this platform." I know that VT-x is enabled (even though I don't know what all that means).

Right on, Claydoh! I made a Windows flash CD, and it worked perfectly. I have the nagging suspicion that I should have thought of that, since updating the BIOS is pre-OS, as it were. I am grateful for your help.
