If you can tell us what model of motherboard this is, we can maybe
tell you what key. If you have another Debian machine somewhere,
use dd to write a netinst.iso to a USB stick and boot from that?
Many old machines respond to DEL key tapped repeatedly on first booting up
F1 / F5 / F7 are all possibles: F12 is usually for a one time boot
You may need to set priority order for BIOS/MBR/Legacy and UEFI boot order
separately.
