BIOS for an HP Pavilion 15 built on the Quanta R62 motherboard, part DAOR62MB6E0, revision E, packed in a 3.41 MB RAR. The board number is written with the letter O, where Quanta labels normally read DA0R62, with a zero. Older Quanta boards like this usually use smaller SPI chips, so make sure the extracted image size matches the installed chip. Back up the original firmware with a programmer before writing, and check the revision on the PCB.
