A. When you try and change screen resolution, Windows NT asks you to test it, if you ignore this and set the display to a resolution that causes a problem your only course of action to to boot in VGA mode, and then once in VGA mode set the resolution back to something you know works.
- Reboot the machine
- Select the option
Windows NT Workstation Version 4.00 \[VGA mode\]
If you find you don't have this option edit boot.ini and add a line similar to your normal NT Workstation startup with the /basevideo /sos, e.g.
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows NT Workstation Version 4.00 \[VGA mode\]" /basevideo /sos
- The machine will boot in base 16 colour VGA mode
- Select the Display Control Panel applet (start - settings - control panel - display)
- Click the Settings tab and change to a resolution you know works (use test)
- Click OK
