I've downloaded the Service Pack for ProLiant 2013.02.0 .iso, burned it to DVD, and verified that it was successfully created:

However, when I boot using the DVD, the DL365 (G1) complains:
Warning!!! Unable to mount the file system [cdrom] Warning!!! Unable to mount the file system Dropping to a shell. Good luck! /bin/ash: Can't access tty, job control turned off.
So I checked the Server Support Guide for Service Pack for ProLiant 2013.02.0 and verified that SPP 2013.02.0 does provide support for the DL365 (G1). In fact, it provides 80 packages for the DL365 (G1)!
What could be causing SPP to fail when booting?
