You can't. But no PC today allows you to change without a monitor.
i bought an ASUS P5GD-1 from here:
and, apparently, it doesn't have a VGA out. ??? ???
i already had an old nvidia PCI video card, so i put that into the top PCI slot.
so here's the issue i knew i was going to face:
how can i change the BIOS settings without a monitor?
any help would be greatly appreciated.
Thanks in advance,
