How does the firmware get updated? Download just has a couple of .bin files.
Those are firmware binary files to be used for someone to flash a new eprom. Looks like they supplied the 256K and 512K version depending on the chip size you use.

Presently in the 1124P (mine anyway) is a standard type 27C512 (64x8 KB) OTP eprom (not to be confused with its brother which would be a UV eprom, that is eraseable).

This means the OTP (one time programming) chip has to be removed and thrown away and a new blank purchased and flashed with the supplied binary files. You need a eprom flasher to do so along with the blank chip.

Note that Behringer loves to put hard glue on their parts and it would be a bit of careful messing around to tease that chip out. See my attached photo.

Anyway, you need a blank 27C512 and a eprom flash programmer with the module that accepts a 27C512 eprom.
