Can it be done? How?
Hey guys,
Conventionally the motherboard BIOS/firmware is rewritten with an updated BIOS version using an updating utility loaded from a floppy diskette or CD, but can the motherboard BIOS/firmware be flashed through the OS using the ACPI software interfaces both in the OS and the BIOS? If it can, how? I've heard it's possible and has been done, but it's also apparently incredibly risky. Is that because OS processes can detect the updating process, interupt it and screw it up? I've googled, but come up with nothing. TIA...

Read your motherboard manual and see if your board has that feature. Many of the new boards do. If available it works like a charm.

The only non-boot floppy method I trust is the way Intel does it - the bios update is a Windows installable that automatically reboots the computer and does the flash on startup. The Award self-flash is pretty good too - where you put a floppy in with the bios file and press Alt-F2 or something like that on startup.

Thanks guys, sorry I didn't reply sooner, juggling school and work lol
I don't need to update my BIOS yet, I'm not having any chipset or device recognition issues or device driver issues, I was just thinking about how it could be done through the OS. So it can only be done if the BIOS has an update feature that the OS can see, obviously through ACPI. That's cool, I knew the BIOS had to have a software add-on or feature to make it possible, but I didn't think of that. glc, that sounds pretty good, thanks for that. I had an idea that Intel might've had a unique way of doing it. Thanks again guys!

Both of my socket 478 boards feature a Windows-based method of flashing the BIOS. I don't see how it's risky. Step 1: Download and install utility. Step 2: download BIOS update. Step 3: Follow on-screen instructions after running utility. I like lazy methods!
