Question about "disabled display adapter" and VGA adapter.
Posted by ShowSun on October 27th, 2007


What's the difference between "disabled display adapter" and "standard vga
graphics adapter"?

Standard vga adapter seems to use vga drivers. What driver or no drier is
used for disabled display adapters? If no driver is used for disabled display
adapters, then how does the OS operate it?
Thanks a lot!

What leads you to think that a "disabled display adapter" is being operated
at all? The very definition of "disabled" is that the system won't load a
driver for it, and hence it will not be used.

I think a "disabled display adapter" is being operated because a "disabled
display adapter" still can dispaly pictures and i still can see vga.sys is in
the module list when using windbg lm command. And computer requires rebooting
when installing drivers from "vga adapter" mode or when adapter is enalbed
from rebooted "disabled adapter" mode. So i think it would be the same for
"disabled display adapter" and VGA adapter.
