Hi All
In windows "device manager", i saw this of my display card (intel
810), Memory addresses are 44000000-47FFFFFF(64M),
40500000-4057FFFF(512K) and A0000-BFFFFF.
My question is , does these two address 44000000-47FFFFFF(64M),
40500000-4057FFFF(512K) are mapped to the display card memory directly
? If yes, we don't need to do the blanking? and how can we get these
address from BIOS?
If no, then i guess the OS need to do the blanking to map these two
address to the display card manually.
Another thing i found is, windows allocated a huge memory address
for Raedon display card (8M). Don't know why. Memory address are
E0000000-E7FFFFFF (128M), 2000-2FFFF AND A0000-BFFFF.
thanks
