My hard drive and DVD drive are not being detected by the BIOS when I go in to the boot option menu by pressing F12. When I put the hard drive in a different computer it's being detected. I am assuming it's either the mother board or the BIOS.

Since the HDD is not being detected I have installed Ubuntu on a flash drive, but even that has become so slow, that it takes around 5 minutes for it to boot.

I want to flash the BIOS before I think of changing the motherboard. I have downloaded the updated file and it has a flash.bat and a afudos.exe. I have to run the .bat file. I downloaded the Dos in a box and went to the DOS directory where the .bat file is and tried to run it, but it gives me the error message "This program cannot run under this operating system"

Any help would be appreciated
