Updating asrock bios without floppy
Notice that on some modern distributions, Step 4: Reboot, flash, reboot, enjoy your new BIOS Finally reboot your machine, make sure that your CD drive is first in the boot sequence, and then run your BIOS upgrade procedure when the CD boots.WARNING: Flashing motherboard BIOS is a dangerous activity that can render your motherboard inoperable!In other words: If the mount went without errors, copy BIOS flash utility and new BIOS image to the mounted floppy disk image.You'll probably have to unzip the archive you downloaded from your motherboard vendor site, to get to those two files.You can also find a local copy of this image attached at the end of this article.
If you're making a CD ISO and have no need to "limit yourself" to the standard formatted floppy size of 1.44Mb, you'll have room for bigger files and/or more tools if you use the 2.88 version of FDOEM: FDSTD.288"standard" image has a bunch of irrelevant (for THIS purpose) utilities, and IMPORTANT! Also, if you look more closely, the whole procedure - except the very final step - happens at the linux prompt.
OTOH, BIOS update is dangerous because of some other things.
Namely, if anything goes wrong during the update process (you lose power or similar) you will finish with a broken motherboard, and thus your computer will become completely inoperable (even though the OS itself is not affected).
", but I decided that it would be too long so I shortened it and made a mistake(? Because Free DOS does all the work of flashing with the BIOS vendor flash utility, you didn't show us how to do it directly from linux. I had to upgrade an old machine that did not have Windoze or a floppy disk. That's exactly what I tried to accomplish when I decided to write on the subject.
If you read something like this "Build a High Performance Cluster with Windows (no UNIX/Linux)" and in the article it says download Cluster Knoppix or some other livecd cluster oriented distro. And english is not my mother tongue, as you may noticed. The information you provided saved me a trip to the computer store to buy the floppy, and a trip to a friend's house to make a Windoze boot floppy. It is amazing what you can do if you have the know-how! As Linux gets more popular, more and more people will need tricks like this. I don't understand why others bash it - while you are technically not flashing from linux, the target audience is those who run linux or some other unixlike os.
uses UMB for lots of stuff, which you MUST NOT DO when updating BIOS. My sincere apologies if some of you were mislead thinking that you could flash your BIOS from a running Linux, I'm really sorry, this article is not about that. ;) I am not being picky about the correct words, I'm being picky about the things as they are.
