Novell ZENworks 10 Configuration Management
The ZCM10 was configured so that the PXEMenu was always enabled.
Since the server was a DHCP Server, the following line was added to the top of the DHCPD.CONF file:
option vendor-class-identifier "PXEclient";
The menu, however, was still not appearing during the PXE Boot.
Imaging using manual mode worked.
There appeared to be some type of corruption in the DHCPD.CONF file.
Once the file was manually recreated, the PXEMenu began appearing properly.
