Dell Intel PRO Family of Adapters - Manual (Page 13)

If your PXE client receives a DHCP address, but then fails to boot, you know the PXE client is working correctly. Check your
network or PXE server configuration to troubleshoot the problem. Contact Customer Support if you need further assistance.
Post hang may occur if two or more ports on Quad Port Server Adapters are
configured for PXE
If you have an Intel® Gigabit VT Quad Port Server Adapter with two or more ports configured for PXE, you may experience
POST hangs on some server systems. If this occurs, the suggested workaround is to move the adapter to another system and
disable PXE on all but one port of the adapter. You may also be able to prevent this problem by disabling any on-board SCSI
or SAS controllers in your system BIOS.
