How do I get to T530 BIOS setup?

How do I get to the T530 BIOS setup? I press ENTER when prompted, then press F1 when prompted, but that takes me to the Intel PXE prompt. If I hit CTRL-S I get into the PXE setup menu, but when I exit that (or if I never hit CTRL-S in the first place) the computer just sits there and never gets into BIOS setup (and never boots, for that matter).

I know I can get into the BIOS because I did get into it once (only looked around, didn't change anything and definitely did NOT put it into UEFI-only mode). But I don't know/can't remember how to get past the PXE thing. Personally, I'd love to just disable it because I am never going to and don't even want to do remote network boots.

When the computer is booting, spam press F12 until it enters set up.
Then pres the arrow down a few times to highlight setup, and press enter.
