Those images aren't really flash images, but instead are images designed to be downloaded by the webpal via a
webpage. They include code that reprograms the flash with the image, contained, probably compressed with some
technique within that binary.
No one has reverse engineered the format to figure out how to extract the uncompress flash image or how to
build a website that you might download them from. I think they would need to be correctly tagged for the
Also, the code only supported a specific ethernet interface that came with the webpal. If you have one of
these, it might be worth your trying to reverse engineer things to
try to extract out the uncompressed flash image from the erx file. Or trying to figure out how to
use the webpal itself to upgrade itself. However, if you just have a random ISA Ethernet card, you
are out of luck. And, sorry, I don't know what the ethernet card used in the original webpal was...there
was discussion on this in very early posts so you might want to look through those if you want more info.
There were also someone who did a "wget" command on the webpal site when it was still up...that might
help you if you want to try the upgrading technique. That is also in the older posts.
If you get a flash image, I could program it. But programming the flash with erx image will just give you
a dead webpal.
