Main BIOS dump labelled MB for an HP 1000 laptop on motherboard 6050A2493101, revision A02, 4.00 MB without extension. The 6050A numbering pattern is used by Inventec, and the revision code appears alongside it on the PCB. A matching EC firmware file exists for the same board. Write this image to the 32 Mbit SPI BIOS chip with a programmer when the board fails to boot. Save the original chip first, and confirm both the board number and A02 revision before flashing to avoid a mismatch.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bios_laptop. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
