I've read that i can revert my 0705 bios to 0603 by using afudos2.11. Well, it didn't work for me. Can someone who did this to explain in details the steps.
Here is what i did:
1. Create bootable flash using some system files i got in internet (probably dos or win98)
2. copy the bios 0603 and the afudos (6 or 7 versions) on the flash
3. restart the pc and set the flash as 1st boot device in bios and exit
4. the flash boots as "c:\"
5. run the afudos /irom_file.rom /pbnc /n
6. restart the pc because the afudos2.11 freezes at the "Advanced Check........." step.
or (getting some error messages like the bios is toooooo old and so on from the other versions of afudos)
