Ronnie, The issues I see that you are having is this. First off the 2008 media is in DVD format, is the drive in the 2500 a DVD-ROM or CD-ROM? The second is the 2500 won't support using 2008. Lastly, with the drives, you will need to access the BIOS on startup (F2) and then go to Intergrated Devices and make sure the SATA port, or Raid is enabled. If raid, has that been configured?   Let me know how it goes.
I'm trying to revive an old Poweredge 2500 which starts up with the error - No boot device available, press F1 to retry or F2 to enter Setup utility I have 3 drives on SCSI Hot channel A, and also have a CD ROM on this channel too I've set the boot sequence to boot to CD Rom first so that I can perhaps just install Windows Server 2008 and get things back up and running But it's not booting to CD Rom.. its just starting up and returning the No Bot Device Available Is this dead or can I revive it somehow? thanks
