Hi NG,

i have installed the Gart-Driver on my WinXP, but Gart was disabled in Bios.

Is it good to enable that? What does Gart do?

Thanks for helping!
Joerg

PS: Board is K8N-E

There is one setting called "GART error reporting" and
the manual says to leave it disabled.

For info on GART, there is this:

Basically, the GART allows fragments of main system memory
to be assigned addresses that make a linear address space for
the graphics card and its transfers from/to system memory.

The GART lives in the Northbridge. There is a definition in
the 875 Northbridge datasheet:

"GART Graphics Aperture Re-map Table. GART is a table in
memory containing the page re-map information used
during AGP aperture address translations."

You can find more info by looking for "Aperture Translation"
in the 875 Northbridge datasheet:
