BIOS image for the Acer Aspire 4736Z, labelled as tested working and tagged with version 1.06. The name mentions Mobile 4, which points to the Intel Mobile 4 Series chipset family. The 1.00 MB size matches an 8 Mbit SPI flash chip, so check the chip marking before writing. The file has no extension, but a programmer such as CH341A or RT809H can still load it as a raw binary. Read and save the original contents first, then erase, write and verify. Confirm the motherboard matches this model before you flash.
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 →
