I do not see around how to upgrade bios. In my ibm thinkpad t20 there is only fc7 and bios from the past century. IBM supplies update as a MS *.exe. How to proceed? I am a bit afraid to do it by wine since I know to upgrade bios is the delicate problem.
Does anybody tried?
Dell distributes .exe bios updates as well, but the updates are runnable from DOS.
google for freedos boot disk or something like that. I know people have been able
to put DOS on a USB memory stick and update that way.
