HP zv5000 notebook will not launch kernel off installation media

[Jonathan Feally]

Has anyone gotten FreeBSD to run on a zv5000? I have the version with an 
AMD 64 chip, and would like to dual boot. I've been a long time user of 
FreeBSD, but never on a laptop. Currently it will start to boot off the 
cd, load the kernel, and I can drop to the /boot/loader command prompt. 
However once I run the command boot from there, the cursor spins a few 
times, stops, and about 15 seconds later the machine powers off.

I have tried turning acpi off, even the full safe mode as /boot/loader 
calls it, but all yeild the same result, spin cursor and power off.

Any Suggestions would be great!

Thanks Jonathan
