Yes, I did flash it from bootable dos with option of /all. I'm guessing the BIOS would look for my S/N or Service tag that is a freedos version. In my other notebook, V3000 series that came also with freedos, changing the DMI setting do the job. But I can't find it for Acer. My Acer is a brandnew Aspire, Acer may have figure it out about the flashing BIOS with /all option in DOS environment. I'm still hoping anybody can help.
