I'm sat here thinking exactly the same thing! (pretty strange that when I put it into google its come up with a current post and not one 3 years old!
Only difference is that I have an Advent 7009 (Mitac 8575). And I have downloaded my bios's from the smae mitac service site. And again all the rar/zip file contains is the bios and flashit1.exe
I have been scouring the net to find out how to use it but havent found anything specific other than the general idea that you make a boot floppy (good job i have a usb floppy drive as my laptop doesnt have a floppy drive.... guessing it will work from a usb one??) then put the flashit utility and the rom file on to it then use dos to load it....is this right?
Ive also found that the version ive doanloaded is newer than my current one, but mitac dont seem to supply any info on what changes are made between the versions
So yeah, any info on how to use this would be much appreciated
