system hangs on boot up

[James Heck]

Hi. I am attempting to install freebsd 5.4 on a toshiba satelite a25 
laptop, in a dual boot scenario with windows xp pro. I have the media 
on 3 cds: one boot only, cd 1, and cd 2. When i boot from the bsd cd, i 
get to the devil screen and select normal startup. It then loads up 
some things and gets to this, where it just hangs and i can hear the cd 
stop in the drive: ata0: channel #0 on atapci0.

I was instructed to look at the handbook, but that did not seem to get 
me anywhere. I just updated my chipset, but my bios is a good two years 
old. After looking at the handbook it seems like this is indeed an acpi 
issue, any help is greatly appreciated!
