If you can see the beginning of the boot process, your settings should be correct.
After the 3 chimes, does the hard drive light continue to flash, or the Green DSPs on the back begin to flash? At the 3 tones is a popular spot for the unit to freeze. It will not continue to boot - just sit there and not respond to the keyboard. Try the Spacebar or enter after the 2 DPSs start to flash. If you have not mapped your Function keys, they may not do anything for you.
Buried in the warehouse (on top of the cases actually) are boxes of documentation. I don't believe there is anything beyond the guides your dealer should have supplied to you (user guide, admin guide & q-cards). If that was ages ago, when you call about the case, ask for pricing on the paperwork.
