Resume from Video Off Sequence
A2-4 Resume from Video Off Sequence
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.
The resume from the Video Off event enables Reload / Break Event of the BIOS Setup when
the BIOS is turned off. However, if it is turned off by the OS, it does not affect Reload /
Break Event of BIOS Setup.
