Intel Matrixraid on amd64

[Dieter]

i386 vs amd64:

If you're updating from 6.x to 8.x (or even 7.x) amd64 needs either APIC
turned on in firmware, or a custom kernel with 'device atpic'.  Device
atpic was taken out of amd64 GENERIC in 7.0.  :-(  On my mainboard this
resulted in not having any disks available.

sysinstall:

If it is a sysinstall problem, you should be able to install 8.0 by hand.
Something like

export DESTDIR=/os/new/
for foo in base doc catpages dict games info manpages ports lib32
do
  cd ${foo}
  sh ./install.sh
  cd ..
done
cd src
sh ./install.sh all
cd ../kernels
sh ./install.sh generic

Then edit files in etc as needed.
