ZyXEL EPROM images are in a binary format.  However, if using a programming
setup that supports multiple flavors of "binary", such as Data I/O's Promlink
software, choose the "Absolute Binary" option.

Soenke Behrens (behrenss@Informatik.TU-Muenchen.DE) and Brent Mosbrook
(brentm@zyxel.com) [ZyXEL USA] explain that the ROMs are in binary format.
They also mention that on most burners, you just load the file, identify it
as a binary file, and specify the starting address of 0.

David Bowerman (1:153/290) [Fidonet] mentions: Verify the EPROM against the 
file image, this is important as EPROMs do wear out after repeated cycling.

Alan Brown (alan@papaioea.manawatu.gen.nz) writes:
If an eprom fails verification, it should be placed under a standard
eraser for a minimum 30 minutes, then reprogrammed using a slower algorithm.
[This may be a way to "recover" a "worn-out" EPROM.]  In all cases, eproms 
should be given "hard" (30 minute) erases every 10 reprogram cycles.
