BIOS for the Acer Veriton N4660G compact desktop, with PIQ37L as the motherboard designation, archived in a 6.53 MB RAR. No version is given, so if the board still boots, note the current release before swapping firmware. A file like this is written to the SPI flash with an external programmer when the machine fails to post or a firmware update was interrupted. Read and store the original chip contents first, match the board name on the PCB to PIQ37L, and check the image size against the chip.
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.
