amd64 gives panic message when booting CD

[Michael T Ehlert]

Hello-

I have a server box with an Intel s5000vcl motherboard and 2 dual-core 
Xeon procs. I was hoping to run FreeBSD 8 on it, but when I try to boot 
the amd64 media I get

panic: No BIOS smap info from loader:

I've Googled about and found chatter relating to the message, but no 
work-around. I'm not a guru, so I'm a bit stuck. Any guidance would be 
much appreciated :D

Thanks,
Michael
