[CentOS] Install help on proliant 8500 please..

Ok, here's what iam trying on,, a compaq proliant 8500 server with 8 xeon 550mhz processors, 6 gig ram,, i just installed centos 4.1 on a proliant 3000 dual 550's and 2 gig ram and went smooth as silk, just got the 8500 and it seems to be in good order, but when i tried (twice) to install centos 4.1 it stalls shortly after a screen of stuff installing and the last two items are something about usb ports (no usb on this or the other server), i then tried fedora core 3 for just a test and it stalled like centos but on the ide/floppy line, i would really like to get centos 4.1 installed on this machine so any help/insight would really be appreciated,,,
