BIOS for the Dell Precision T1650 workstation, with the name indicating separate 8 MB and 4 MB images. Dell desktop boards of this generation often use two SPI chips, so each dump must be written to the chip of matching capacity. Use an external programmer to recover a unit that fails to post or was bricked by an interrupted update. Read and keep both original chips first, since they contain service tag and system data, and check every image size before writing.
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 @biosarchive. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
