Hello. First of all, thank you for flashrom. I have an ECS k7vta3 mobo with VT8233A southbridge.
# flashrom -r bios.old
First, save this backup somewhere. If you want to be really paranoid/safe also save it on external media.
I have the latest BIOS (k7vta330d.exe) here. To write it I would simply run
# flashrom -wv k7vta330d.exe
right? Should I add any -V just in case too?
You'll need to get the bios out of the exe. Try all of these:
unzip cabextract unshield 7za
Then find the file with an appropriate size. It will be the exact number of bytes as the backup you have made.
Then, recent versions of flashrom automatically verify after writing so you do not need a little v. A big V would be nice for debugging any issues that occur.
Now, make sure that you have time (at least a day, maybe more) to leave the machine running in case the flash fails. If it does fail, it is likely some software protection that can be disabled with some investigation (some reverse engineering by a developer, a patch being written, applied by you and a new flashrom being compiled by you).
Also keep in mind that all flash updates have some amount of risk.
So the command you'll want to run is: # flashrom -Vw $newfile where $newfile is the image you find after uncompressing/extracting the .exe provided by the bios vendor.
Good luck (and please send success/failure reports to this list),
