boot display settings

[lampemi]

Hello,

I've got following problem. I have T61 which is always used with a lcd projector. On the T61 disklock is activated. I want the T61 to display the disklock on the Thinkpads LCD and not on the projection. I can have this working when I switch the bios setting to Boot display: thinkpad LCD. This works until you logon in windows. When you have once logon in Windows XP the bios seems to forget he has to display during boot on the Thinkpads lcd and not on the projection. I've tried several settings but nothing works. I'm thinking it has something to do with the Intel driver settings.

When I'm doing this on a T42 it works when I use the boot display setting VGA + LCD. On a T61 it doesn't work.

Any idea how to fix this?

greetz,

Michel
