on any type of installation (nfs/ftp/cdrom/localHD) the installation freezes upon detection of the cdrom or the loading ot stage2.img on our compaq deskpro 4000 which is a pentium pro 200 with 256mb of ram and a 2.1gb IDE western digital HD.
Please try the latest boot.img and bootnet.img updates located at out support web site. http://www.redhat.com/support and reopen if the problem still occurs with more detail.
