855GME - problems if machine is booted without monitor in 1024x768 mode

[paulfoel]

Running Windows 2000 workstation SP4 on a single card PC.

If I boot with monitor connected, it all works fine.

However, if I boot with no monitor connected, wait for it to boot,
then connected the monitor cable, I get no signal on the monitor.

Weird thing is if I subsequently power off, connect the monitor and
boot it still wont work. Only solution then is to reinstall the
machine.

Its as if the booting with no monitor is knackering things, as if its
switching the machine into a different mode or something.

BTW. I can boot into Safe mode though at all times.

EDIT: Done some research and it appears that windows/grphics card may be turned off the output if machine is booted without monitor attached. Is this correct? If so, how do I stop it doing that?

its probably outputting to an lfp that isnt plugged in
