When I boot a machine from disc 1 of 2, Centos 6.5 install dvd, I get to a grub prompt.

I have no idea what to do from there, but clearly something isn't right. Shoudl I try to download centos 6 again and burn new discs?

Probably. Make sure you check the checksum of your downloaded images and that the DVD burn checksum finishes. When transmitting that much data over two mediums errors can creep in.

I (finally) understand the issues, which I will note here, in case someone else needs the info in the future.

The installer from the DVD sees the disks in a different order than the machine does when trying to boot itself. It turns out that the installer put the OS on (HD3,6) with /boot on (HD3,0) when running from the DVD. When the machine tries to boot, the OS disk is seen as (HD0,6) and /boot is (HD0,0).

I pulled the disks from my 3ware raid card, so the installer would see the boot device as (HD0), did (another) clean install and the machine now can boot itself.

Unfortunately, somehow pulling the raid disks seems to have corrupted the partition tables, and the machine no longer sees those filesystems... That is for another thread.
