Oooh!  This sounds like the problem that others here
just helped me with!  I had to disable DMA on my ATA
drive.  For me it's an archive store, so I'm not hurt
by it; you may be.

To do this, you have to talk to the boot loader.  I
don't recall how the CD-ROM is set up, but if you
get a countdown prompt reading something like
``Booting in 9 seconds.  Press <Return> to boot
you can hit the space bar (anything but return) to
talk to the boot loader.  At that point, you issue
the command

        set hw.ata.ata_dma=0

and then


to continue the bootstrap.

After the install, you may have to do this again;
once FreeBSD is up for real, edit the assignment
(without the `set ') into /boot/loader.conf .

If you run this way, you will see interrupt activity
soaking up the CPU during disk transfers; my preferred
monitor is

       systat 1 -vmstat
