Why does the EFI shell not detect my Windows DVD?

I'm currently looking into (U)EFI for the first time and am already really confused.

I insert the Windows Server 2008 R2 Enterprise disc into the DVD-ROM and boot into the EFI shell. The shell will automatically list all detected devices, which are:

blk0 :CDRom - Alias (null)
      Acpi(PNP0A03,0)/Pci(1F|2)/Ata(Primary,Master)/CDROM(Entry0)
blk1 :BlockDevice - Alias (null)
      Acpi(PNP0A03,0)/Pci(1F|2)/Ata(Primary,Master)

To my understanding, it should have already detected the filesystem on blk0 and should have mounted it as fs0. Why is that not happening? If I insert a USB drive, it gets mounted just fine.

The board is an Intel S5520HC in case that makes a difference.
