I thought people usually say you should keep HDs and CD-ROMs separate so the CD-ROM does not slow down the HD. But maybe that is not
true for newer systems any more, or it has always been an urban legend...

Anyway, I had problems with the current configuration before, because running only the CDROM on the second controller caused the
machine not to boot unless I used "ide=nodma". That however caused problems with a "lost too many ticks" error.
So I figured mixing HD and CD-ROM would make even more problems than having the CDROM by itself on that controller port.
But I guess I was wrong. I now have both HDs as master on the two IDE ports and the CD-ROM as slave on the secondary IDE and
everything works fine. RAID 1 has normal speed, install ran through at normal speed and I can now even boot without "ide=nodma".

Thanks for the suggestion!
