I love virtualbox. Right up until I don't.
I got this error:
PXE-E06: OptionROM requires DDIM support.
And after some searching, I found messages like this....
PXE-E06: OptionROM requires DDIM support.
The system BIOS does not support DDIM. The BIOS does not support the mapping of the PCI expan-sion ROMs into upper memory as required by the PCI specification. The Intel Boot Agent cannot func-tion in this system. The Intel Boot Agent returns control to the BIOS and does not attempt toremote boot. You may be able to resolve the problem by updating the BIOS on your system. Ifupdating your system's BIOS does not fix the problem, contact your system administrator or yourcomputer vendor's customer support to resolve the problem.
....and....
PXE-E06: Option ROM requires DDIM support.
This message should not be seen in a production BIOS. PCI option ROMs must always be installed as DDIM option ROMs (they must be installed into read/write upper memory).
Eventually, what fixed it?
Delete the File "PXE-Intel.rom" which is located in the Extension Pack directory - in my install, that was
C:\Program Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack
