I have been trying ot get mkflash to work with my ASUS P5V800-MX motherboard swhich has a VT8251 chipset since yesterday. The xbox drive shows up in the bios everytime but when i use MKflash is alsways gives me a Drive not found error. I have spent hours reading posts and have no idea what to try next. I have unplugged all other drives, disabled all IDE drives. I do not have the SATA on raid. Any help would be appreciated.
