BIOS .bin 1.00 MB Shared

Programmer read labelled with a Macronix MX25L6405 chip and a May 2019 timestamp, yet the file is only 1 MB, much smaller than the 8 MB capacity of that 64 Mbit part. That mismatch suggests a partial read or a wrong chip setting, so treat the contents with care. No device or board number is named. Re-read the chip and compare checksums, look inside with a hex editor for identifying strings, and do not write it to a full-size flash without understanding why the size differs.

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.
