Re: External monitor with Compaq Presario 1600
I was playing with this some more, and I discovered that I /can/ swap
physical displays in the lilo-menu screen before I choose a boot option,
but this functionality is lost after choosing Linux. I can also swap in
W2K, but not in the BIOS.
It's really puzzling to me why I can swap in lilo but no in Linux.
Can anyone help me out?
Regards,
Arjen
