Frequently asked questions
Which laptops use the MBX-205 motherboard?
File names in the catalog tie MBX-205 to the Sony M850. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
What should I check before flashing the MBX-205 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.
