The error is a line not found in cygwin1.dll, so it is entirely possible that I have messed up cygwin along the way somewhere.

The flash-kernel thing is strange. To get the ftp client to send it, I first need to telnet to the empeg and rw. Then send the file. Then ro. Then sometimes when I reboot I have the new kernel, sometimes not. It used to work 90% of the time, now about 20%.

Most of my boxes are unix or linux, and I can easily hook one up to talk to the empeg, but I still don't understand the format of the .disk file which is gziped into upg_pumphda5. What do I use to create that file?
