Jordan, It turns out that Alpha's have some slick Intel BIOS emulation called the ``Alpa BIOS.'' This is used by both ARC and SRM to set up add-in cards. I had a long chat with Dave Hunter today, and Dave is going to talk to him friends in NT-Land that know the most about this. The more he and I talked, the more it sounds like this the technology that you need to be looking at for raw boot. My guess is that you will be able to use it get to the traditional FreeBSD bootstrap code, similar to the way you do now with the modified CMU Mach/Oliveti-Intel boot loader [which calls in the ROM-BIOS]. You are still likely to need help with the PAL code. You will need to support some of it, the question is how much and what. Clem
