Re: AMD 760 (761?) AGP

[Steven Spence]

If you have it as a module try loading it with  agp_try_unsupported=1.
If its not a module try appending it to lilo.  I have that chipset and 
everything
works fine with those options.  I have a GF2U however not a Radeon.  I can
get 4x working with side band addressing and fast write.
