Frequently asked questions

Which laptops use the MXBA00 motherboard?
File names in the catalog tie MXBA00 to the ASRock B450 Steel Legend. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of MXBA00 do I have?
Files for this board mention Rev A01. 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 MXBA00 boardview file?
The boardview for MXBA00 is available as .FZ. .FZ usually opens in OpenBoardView (free) or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the MXBA00 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.
