"Something to try - worked for me in the past..
1) download the latest ROM from compaq (v1.87)
2) Kill activsync through the task manager
3) Hard-reset your iPaq (do not enter the Bootloader)
3) drop your iPaq in the cradle and cancel all windows messages about installing a new driver
4) run the flash upgrade.
The compaq flash upgrade should be able to find your system and replace the flash memory - last time I reflashed mine it gave me an error and I ended up with a white screen with 3-4 virticle lines, this took care of it."
I am not sure it will be much help, but good luck.
Most everything else I found wound up being archived or 404 Not found...
