Frequently asked questions

Which laptops use the MBX-270 motherboard?
File names in the catalog tie MBX-270 to the Sony VAIO SVE14. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of MBX-270 do I have?
Files for this board mention Rev 1.0, Rev 1.1 and Rev 1.2. 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 MBX-270 BIOS?
Read the original chip with a programmer and save two copies before writing anything. Some archives include EC/KBC firmware, which may need to be written to a separate chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
