Frequently asked questions

Which laptops use the MXGQ20 motherboard?
File names in the catalog tie MXGQ20 to the ASRock B85M PRO4. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of MXGQ20 do I have?
Files for this board mention Rev 1.04. 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.
How do I open the MXGQ20 boardview file?
The MXGQ20 boardview comes inside an archive whose name does not state the format. Unpack it and check the extension; most laptop boardviews open in OpenBoardView or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the MXGQ20 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.
