BIOS image of 4.00 MB labelled hp pavillion10 tchsmat, apparently for the HP Pavilion 10 TouchSmart, though the name has no board number, revision or version and no extension. A duplicate copy also exists, so a checksum comparison is useful. The image fits a 32 Mbit SPI chip and can be written with a CH341A or similar programmer, or inspected first in a hex editor. Read and save the original chip contents before erasing, and match the board number on the PCB.
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 @biosfilebins. 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 →
