HP EliteDesk 800 G2 - BIOS settings?

[VorlonFrog]

I got one of these used desktop i7 systems a few weeks ago, and finally received the m.2 PCI card to install the SSD for the system disk. Got everything setup and running last night and this morning, UNTIL I told it to reboot/restart just now. Seems it's not restarting, probably because there's no keyboard or mouse connected and the display is turned off. Anyone here familiar with the specific BIOS settings on this thing, and know how to get it to reboot successfully without user interface devices connected? I know there's a few of you here running this system.

Thanks in advance!

Never mind. It rebooted, but now the network settings appear to be an issue. Gonna have to cable up the keyboard and mouse anyway. Darn it.
