Which laptops use the LA-7321P motherboard?
File names in the catalog tie LA-7321P to the Asus X43B, Asus K43U, Asus K43Y, Asus K43BR and Asus X43B-COMPAL. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-7321P do I have?
Files for this board mention Rev 0.22 and Rev 1A. 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.

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.
