Sony :: [Vaio VGN-FW11e] Output To External Monitor During POST

I just bought a used but fully working Vaio VGN-FW11e with a cracked screen (got it for a good price). The lcd-panel had been removed but the lid is intact. The cracked screen didn't bother me since I planned to have it permanently hooked up to my projekter using the VGA-output.

The problem is that it doesn't seem to turn on the VGA-out before Windows has loaded, i.e. it is impossible to see the POST/loading of BIOS. When trying to restore Windows to its factory settings (since the old owner had left all his files and folders all over the place) using the Vaio Recovery Center something went wrong and now I'm left with a dead system.

When turning the computer on I can hear and see what seems like a proper POST, i.e. the hard drive spinning, the dvd drive spinning etc. But a few seconds after start, when it's supposed to start loading Windows it just stay still, most likely with some kind of error message.

I desperately need to be able to activate the VGA out during BIOS to be able to reinstall Windows. According to Sony this is not possible. But it sound almost silly since every other laptop I have had has been able to output a picture to VGA directly during POST. Is there some way since the obvious Fn-F7 doesn't work?
