GART? What is that?

[Joerg Heinrich]

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!

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:
