This question is mostly intended for Mark...

Can anyone provide some more information about the builder image format used by the empeg? I've run strings/hexdump and figured out a few obvious sections, but haven't had time to finish. What I'm particularly interested in knowing is who is responsible for pumping the drives, and where this is controlled - does the Windows software know pump commands or does it get told what to squirt down the serial line via the upgrade image?

FYI, the recent bigdisk builder images will not install on my empeg - the only one I've been able to use is an older v3 alpha bigdisk image. But I'm suspicious this is simply a bug in pump (along the lines that I've seen in the archives) since the disk is detected, and it does work just fine (brand new, tested, and using a brand new IDE cable also). If I know how they're laid out, I can play a little bit more by using the old disk.

Jon.
