HP BIOS dump read from an MX77L12850F flash chip in SOP8 package, packed in a RAR archive, linked to Wistron board 213134-1. The ME++ tag in the name most likely refers to a modified or cleaned Management Engine region, and the timestamp shows when the read was made. The MX77L12850F is a 128 Mbit (16 MB) part, so the image should be written to a chip of that size with a programmer such as CH341A or RT809. Back up the original chip and match the Wistron board number on the PCB before flashing.
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 @skclappybios. Enginerys does not host this file.
