Create a bootable Floppy or USB Stick. Select from folder options to see all files and delete the config.sys. Boot to DOS and flash as described.
Well, flashed from original 0703 bios to 1104 with ezflash in the bios. Did some testing and decided to install vista. I downloaded your bios and again tried to flash with ezflash. This didn't work for some strange reason. I also tried to flash with a bootdisk but that gave me problems, just as the hirens bootcd that doesn't even wanna boot on this mobo :-( So I tried the asus windows updater that's located on the p5q-pro cd. I flashed and it told me to power down the pc. SO I shutdown windows, but when the monitor disabled, the computer was still spinning. So after 5 minutes or so I resetted it. It didn't power up anymore. I did all the bios clear tricks, but without luck. The mobo starts (I hear the first beep), but then a big cursor appears an the topleft side of the screen. Well RMA'ing it. Did anybody else had problems with this modded bios? Oh, did the same flashing with asus windows flash on my p5b and p5e board without any problems.
