Flashing bios on Asus P5K Deluxe:

Asus P5K Deluxe uses 2MB sized bios flash ROMs. So best way to flash or update your bios on Asus P5K Deluxe is to use a USB flash drive and the motherboard's own inbuilt EZ Flash 2 function:

1. Even at stock cpu/mem speeds, you need to test for stability in memtest86+ v1.70 and windows before attempting to flash your bios. Don't assume stock cpu/mem speeds means stable as AUTO sub timings or some voltages might not be the right stable combination for your component configuration.
2. Put bios on USB drive
3. Ensure USB legacy is enabled and boot into bios
4. Use EZ Flash 2 in bios to select the bios on your usb drive.
5. Follow prompts to flash and wait until the auto reboot happens.
6. Sometimes it may not boot up straight away, so turn off system, clear CMOS and you should be up and running again.
