PXE status code 0xc8 is PXENV_STATUS_LOADER_NO_PXE_STRUCT.

gPXE initializes a s_UNDI_LOADER struct and zeroes the PXENVptr/PXEptr
fields.  According to the PXE spec these structures should be created
or filled in by the UNDI loader function in the PXE ROM.

I'd interpret this error to mean this particular UNDI implementation
expects a valid PXEptr so it can fill in an existing !PXE structure in
memory.  Normally the UNDI loader function works fine when we pass
zero and it creates its own structure and fills it in.

hpa, mcb30: Any ideas what is going on here?

Are you sure the network cards/boot ROMs are the same as the ones you
tested before?
