I have an AD-40 (Repartee 7.47) at a hotel. It hung on reboot following a power outage. I went onsite, rebooted it, watched it come up to the banner screen. Tested good.

Next day, manager onsite says that it's not answering. I gave instructions for a warm reboot. Called again that evening, still not working. Went onsite, did a warm reboot, system came up to banner screen, all is well.

This morning, another call. Same thing. Had manager reboot, and I've called it every 15-20 minutes since... Seems to be up and running.

It never hangs when I reboot it.

When it hangs, it's after downloading the dialogic boards, and before the "Fixpak 5.1" message. There will be a black DOS-type screen over a blue OS/2 desktop. The message on-screen tells me that the current drive is C:.

Any thoughts?
