I would guess that it is a SCSI controller driver issue. It appears when this server was first marketed all current Redhat distributions were supported which included version 8. There were several SCSI controllers that were available and without knowing the chipset it will be difficult to provide help. If you could post the output of the lsmod command then we could see what module is being loaded. I assume that RH 8 is still installed.
Whether or not the module is still included in a modern stock 2.6 kernel will be the key to your problem. Another CDROM drive will not help.
I'm dying to try that, it's 3am and my wife has a thing about servers in the next room, RH8 is off due to partitioning attemps but i may be able to get the ISMOD results from knoppix?
People always post this server with more currents distros.... Even netinstall versions need to read from the install disk ofter anaconda's preferences are set so it fails, almost like it reads till its mounted and then acnt find it as it doesn't even seek (green light)...
following your advice I have also read that the external scsi driver is being loaded first and that i should use the "expert noprope +"
and force the drivers in that order. per link below.
I believe all the Centos 5 Kernels are SMP enabled already..
lshw -C processor
yum -ivh lshw since lshw is probably not installed by default
or cat /proc/cpuinfo
or dmidecode -t processor
I prefer the lshw method as it plainly distinguished between physical and logical CPU's (logical would be hyperthreading or multiple cores)
dmidecode output is not bad, but lshw format is a lot cleaner imho..
