2d8c37307d Improve Video Hardware Reset
- This change avoids clearing the screen every time an OS reset occurs.  A non-destructive VDC reset is now performed that leaves the screen contents and cursor position unchanged.
- If an application overwrites the video RAM, then the screen may contain garbage upon return to OS.  However, the console will still be functional and the user can just press enter a few times to clear the screen.
