Here is a picture of my Bios as I found my printer, when I got it. In the BIOS the "Onboard Lan Boot" was disabled. No idea why. I changed this setting and saved the BIOS. I connected my cat5 directly to my router and then with the ZCorp printing software open on my computer, I was able to see the printer and use the software set up to make it my default printer.
