I've been using my ipaq normally for a while, and just decided to try to play with it today. Because I've been using it, I know it's been updated to the newer firmware issued by microsoft. I'm not sure if that's relevant but:
After opening it and resetting the BIOS with the jumper, I plug the appliacne back in and it boots up. Memory count is displayed, and then a message saying that the CMOS checksum is invalid and options are being set to the defaults. If I go into the BIOS immediately after this, the only option available for boot sequence is A:
If I reboot, then A: and C: are available under boot sequence. But under no sequence is D: ever available. I've tried resetting the BIOS quite a few times, and this is always the case. Any ideas?
