Need to flash BIOS, can I execute in Wine or have to reinstall Windows?
Will Wine truly run a critical .exe file I need to flash, or must I reinstall Windows temporarily? I have a GUID partition type now and am worried Windows will rewrite the table to ms-dos, thus defeating the purpose of the flash.

neither of them, if you want to avoid trouble.

Usually, the BIOS flash tools come with their own minimal OS. Very often, this isn't more than plain old DOS, because it's simple, it's predictable, it's single-user, single-task. And it runs in real mode, allowing direct hardware access.

So you make a bootable floppy (or create a bootable CD with a floppy boot image), boot from it, and circumvent any influence of a sophisticated OS that might interrupt the flashing process at any time and ruin the mainboard that way.

Uggghhh... Windows...

okay I will try the bootable floopy idea.

Thanls. :-)[COLOR="Silver"]

Which motherboard do you have? Most modern motherboards don't need an OS to be flashed, they come with a built-in tool for doing that.

I've typically used FreeDOS when it was a windows flash utility. This Arch wiki page has some good tools and methods also.

For a quick follow up, indeed I reinstalled Windows, extracted the flash ROM, configured the settings and indeed I now have a working UEFI, no more legacy BIOS. Immediately of course after the reboot Windows started panicking so I quickly popped in Lubuntu, to the Disk Utility, formatted the table to GUID and set my bios and boot partions, rebooted and am installing SUSE now, and indeed SUSE is in complete control, and even on the LiveCd, bootup and much faster indeed.

I still wonder which motherboard you have. I doubt that installing Windows was necessary at all.

I have an AMI motherboard with a Sandy Bridge 2 chipset, with the i5 processor. It looks like the UEFI is still in devrlopment phase but I've read and can imagine how having an UEFI Linux I stalled and any of the 3 types of the "I" series processor, you can really maximize all the hardware's potential and I was impatient. As for alternatives, I tried the dd command and was getting bash errors so I just did it. It really only took 30 for the whole process. And as for data I really had none, and was waiting till I got this done. See or for information on all I've been involved in this week.

+1 TobiSGD.

Most boards where you can flash the BIOS from windows can also let you do it from a USB stick....which I would use over updating from windows any day.

As I've said before NEVER flash the BIOS from Window$.

barnac1e 02-10-2012 05:46 AM

Yeah, I did not know that. They also need to quit catering to Microsoft and only providing. exe files. Even Brother printers provides a Linux specific driver for CUPS for example and if they cannot they arrange for HP compatability.

Glad I found this thread...I am using a Toshiba Satellite L25 and I am having trouble updating my bios...will try some of the methods here. Btw, have no cd drive can only use USB stick, other suggestions welcome if this doesn't work
