Start-up code for x86 (Pentium) targets on GHS

I'm trying to set up a proprietary Pentium-based prototype with The Green Hills MULTI tools. Alas, the default start-up code that comes with them is taylored to a PC-based with BIOS, diskette and the like, already in 32-bit protected mode, which is not my case.

Before playing with Intel's psycho-chip, and guessing when I need an override prefix and where, I wonder if somebody could lend me a hand and providing me with some start-up code for a bare board like mine.

Thanks a lot.
