Frequently asked questions

Which laptops use the Quanta BD3G motherboard?
File names in the catalog tie Quanta BD3G to the Toshiba Satellite A300D, Toshiba Satellite A300D-14P and Toshiba P300D-12Y. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of Quanta BD3G do I have?
Files for this board mention Rev E. 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 Quanta BD3G 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.
