iPac4 prevents computer boot [SOLVED]

Another thing you can try, when you see the Dell boot screen, you can sometimes press 'tab' or similar to hide the logo screen and show the actual POST screen, that might help with debugging, so you can see where it's halting.
Oh, actually, see if there's an option in the BIOS to disable 'halt on error'.

The Boot from Other Devices is actually Boot from add-in cards, and you can't disable it, only push it down the list to a lower priority.
There are only 2 "Halt on" options: Halt on All and Halt on All, but keyboard (the latter is selected)
I missed 1UP's part about some hubs causing this issue and it seems he was right. I'm using a dlink powered USB hub to connect the CP, keyboard and mouse, and if I disconnect the CP from that it works fine. If I plug the CP into the extension cable, it works fine. It's only when I have the CP plugged into the hub that it locks things up. I'm going to try plugging the hub into different connectors on the MOBO (Who knows, I may have it in 1.1 when it needs to be 2.0 or something)

oh wow, interesting. glad you've found the problem then :)

Well, it seems it's a bit more strange than that. It seems that if the hub and the iPac4 are BOTH plugged in, it locks. If either one of them is unplugged, it works. When I tried it earlier, I neglected to plug the hub back in, so I thought it was all working.
It doesn't seem to matter what USB port either one is plugged into either. Looks like I'm going to have to find a new hub or just use 4 individual USB extensions.
Clarification: The iPac4 doesn't need to be plugged into the hub for it to lock. It can be plugged into a separate port, or into the hub. If both devices are plugged in, regardless of the configuration, it locks.

oh wow, that is an interesting conflict!
what else is plugged into USB? is it possible the bios isn't liking multiple mice/keyboards?

The only other thing plugged in is a logitech wireless mouse/keyboard combo, and that doesn't seem to factor in at all.
For now, I've switched to 2 USB extension cables, but in the future I'll have to find a hub that works because my 2nd control panel is going to have at least an ipac and an optipac, and I was thinking of trying out 2 of those topgun II's.
Thanks for the troubleshooting help guys.
