some pcs can be booted without keyboard, most without monitor, but almost
all bioses have very stupid bug: if there is no keyboard attached, bios
halts before boot and asks you to press f1 to continue. To avoid this, one
has to enter bios setup and disable ‘halt on error’ things, or something
along those lines.
there are some motherboards that can boot with no keyboard. mouse and monitor and keyboard is not important for XP!!!
but to the board….
There are some bords that can not boot.
so you have to try to boot without keyboard.
you can also try to explore the bios system (press delete on boot) and look for an option that you can enable/disable to boot computer without the "Press F1 to continue".
my current board does not need keyoard to boot… the keyboard is USB, so ps2 do not detect…bla bla bla
My bios has that option.
