What I meant about the bios is that it's set to boot from a IDE cdrom first then hard drive or CF next, even on the ones that you can't get into the bios setup.
Sounds like what you need is an IDE to CF adapter to install and a normal PC to setup the boot manager on the CF card, these can be found for about $25, do a search here or on Google.com and you should be able to find a couple links for sites that sell them.
I have one that I use to format my CF cards on, in a regular desktop PC the CF is recognized as a normal IDE hard drive and don't require any driver support to loaded unlike the USB CF readers. Then once the BM is installed and setup, just take the CF to the GCT and test.
