I tried installing with several options (noacpi noapm; noprobe; noprobe skipddc noacpi noapm nodma). Always I get the same error. BUT this is not in fac a CentOS problem at all, because I get the same error always when I boot from hd (Fedora Core), IF there is a CD in the CD-ROM drive. (I tried with CentOS 1/4, CentOS 2/4 and a HP printer software CD.) It must be something with the CD drive! Maybe I just have to try another CD drive. - Jussi H.
