Frequently asked questions

Which revision of Asus K40IJ do I have?
Files for this board mention Rev 1.1, Rev 2.0 and Rev 2.1. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
What should I check before flashing the Asus K40IJ BIOS?
Read the original chip with a programmer and save two copies before writing anything. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
