I am new to this forum. I found it looking for a solution to the error message
Broadcom NetXtreme Boot Agent v7.5.14

Press Ctrl-S to Enter Configuration Menu
PXE-E01 Unsupported PCI Device!
I tried to rebooting many times until I came upon the solution.
As nufu wrote above - just take out the CMOS battery and then put it back in place. It worked.
Thank you to the previous poster.
I have found that if you just unplug the power cord from the computer and wait until all the electrons drain from the system (about a minute or so) it will boot properly then. Not all the time but most of the time. just something to try before going through the trouble of pulling the CMOS battery.
I had the same problem as above. I was playing around with new, improvised boards and thought I fried my motherboard! Thanks for saving my computer from the salvage yard and me from suicide!!! lol John S.
Did not work for me. I have a PC desktop OptiPlex 6X 620. I press F12 or F2 but nothing happens. Still getting a message PXE-01: Unsupported PCI Device. Broadom NetXtreme Ethernet Boot Agent Y9.4.4. Press Ctrl-S to enter configuration menu. I also pressed Ctrl-S. nothing happens.
PXE message is a Boot Rom or the system hard drive is bad. REMOVE ALL CARDS, REMOVE ALL RAM.
Remove the DATA cable from the hard drive. Put 1 stick of ram in. It should post to an error.
