We had installed zdm 7.01ir2 and imaging was working well,
also with HP DC7800.
What we had to do for DC7800 we added at the cmd file the nic manually newid="0x8086 0x10bd,e1000"
after that PXE imaging was fine.
Now we installed ir3a and after that the files from sles10sp2 patch.

!!! Our DC 7800 ist not working since that, with PXE Imaging !!!
It looks like NIC will not be identified.

Any suggestion ?
