According to the FreeVGA manual (and IBM manual too):
[quot]O/E Page -- Odd/Even Page Select
"Selects the upper/lower 64K page of memory when the system is in an eve/odd mode (modes 0,1,2,3,7).
= 0 selects the low page
= 1 selects the high page"[/quot]
What effect does this have on CPU reads/writes to VRAM and rendering output? According to what I can find, it's never used and always set to 1 for some reason?
