Ok, I used the detect.com proggie from www.mrbios.com to generate a bios image and description with the following results:
Program: Unicore Chip Detect v0.72 2000.03.10
BIOS Date: 03/01/00
BIOS Type: unknown
BIOS ID: unknown
Chipset: VIA 82C501 rev 4
Superio: VIA 686 rev 27 found at port 7h
For comparison, the only real diff (Other than BIOS) with an early IOpener is the chipset on those is listed as rev 3. This leads me to believe that the two units, at the BIOS level, should be nice and compatible. If someone's found a bios for the IO's that can do USB HD booting for instance, the iPaq should be able to as well. I've submitted this and the IOpener info to Mr BIOS to see if they can whip up such a BIOS for my unit. I'd cotemplate trying a BIOS from a similar mainboard, but I don't want to risk downtime while waiting for a reflashed chip to ship, this is my only iPaq. A braver soul may want to give it a shot and report back if they've got more than one unit they can put under the knife.
