BIOS dump for the Acer Extensa 5230E with a Core 2 Duo class processor on an Intel Mobile 4 Series chipset, marked working at version 1.36. The file has no extension, but it is a 2.00 MB raw image suited to a 16 Mbit SPI flash. It can be written with a CH341A, RT809H or similar programmer. Back up the original chip before erasing, because it can hold ME and system data. Confirm the chip capacity is 16 Mbit and the board matches this Extensa model before you write.
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.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
