I ran into this error message while installing the 2003.1.2 HP image on a MCS-7825H3.
"The installation program has determined that this server model:MCS-7825-H3 is not supported for remote deployment by this os version. Please un-mount any CD-ROM/DVD-ROM
Virtual Media used for remote deployment and try again"
Seems that it didnt like my Avocent IP KVM. I connected a old monitor, ps2 keyboard, and ps2 mouse and the install worked fine.
