[comp.sys.ibm.pc] VGA address question

phil@ux1.cso.uiuc.edu (07/21/89)

The standard VGA adapter for IBM PC and clones has 256K of memory.
I understand this memory is mapped somewhere in the 384K of space
between A0000 and FFFFF.  Does anyone know where?

Now I see enhanced VGA adapters with 512K of memory.  Now where
would THEY be mapped as there is not that much space.  Would they
creep up above the 1 Meg line?
