If the BIOS turns off the Video, BIOS resume the Video. If the OS turns off the Video, OS
resume the Video. Therefore, normally OS resume it under Windows 98 (/Windows 95) and
BIOS resume it under Windows NT/DOS (/Windows 95). And also, BIOS resume Video if
the APM BIOS is disabled under Windows 95/98.
