OS: Netware 6.5
Onboard Graphics: Intel G45 Chipset / Integrated Intel Graphics Media Accelerator X4500HD (Intel GMA X4500HD)

Having to install a new motherbord, the x-windows environment fails: it starts up but the screen is not readable at all, so wrong resolution/frequency.

I tried to find information on how to configure this but haven't found anything usable.
XSetup.ncf doesn't help as it uses itself the graphical environment.

Any ideas where to look?
