BIOS ROM for an NEC laptop on Quanta board DARR3AMB6D0, with RR3 as the platform code, supplied in a 2.29 MB ZIP archive. The DA-prefixed number follows Quanta's mainboard naming, so the board was built by Quanta for NEC. A technician uses it to rewrite a damaged flash chip with an external programmer when the notebook is dead or stuck at boot. Check the board number and revision on the PCB, keep a copy of the original chip contents, and confirm that the image size fits the chip.
