POSITIVO XR2995 U12 & U6

BIOS .rar 3.21 MB Shared

Firmware set for the Positivo XR2995 laptop covering two flash positions, U12 and U6, in a 3.21 MB RAR archive. The pair suggests separate images for two chips on the board, so each file must go to its matching location rather than being swapped. Typical use is restoring boot after a failed update or corruption by writing with an SPI programmer while the board is unpowered. Check the chip markings and voltage of each part, back up what is currently stored, and verify that every image size matches its chip capacity.

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.
