Feeling quite silly now! The stuff that will not run on PC2003 (WinCE4.2) grows evermore, and I feel I would like to 'return' to PC2002
Apparently I need the HP/Compaq upgrade CD which has a 'restore ROM' option to return the rom to PC2002. I do not think that Keef's Canadian link is the IPAQ OEM stuff, so if anyone has the relevant CD I would appreciate a PM.
