This will start the ZMODEM transfer engine that transfers a single binary bootrom image
file to POST using the service port. It should not be used to receive other kinds of binary
image files. If the transfer is successful then POST will program the bootrom image into
the FLASH memory device.
While waiting for the file, POST will display:
**B000000023be50
At this point the operator may transfer the bootrom ".bin" file to POST using the ZMO-
DEM protocol. Refer to terminal emulator documentation for details on how to do this.
After the file is transferred, POST will display:
File transfer and update PASSED
ZMODEM Messages:
Writing to flash:MMMMMMMM-NNNN

primary bootrom." If errors are encountered, POST will display appropriate messages
along with the line:
