I'm waiting to get hold of redhat 9.0, to see what that is like for installation.
So far I have tried the following releases on the 8rda+ board, with a Radeon 9500 Pro
Suse 8.1 - install text mode only, then installed NForce drivers and got network working, but couldn't get graphics to work.
Redhat 8.0 - Graphical Install - Installed NForce drivers, but couldn't get 9500 pro working
Mandrake 9.0 - Had to use text install, and set the flag mem=768M to install, installed NForce drivers, but still unable to get graphics working
Mandrake 9.1 - as above but haven't got NForce drivers working yet, or the graphics properly as uses XFree 4.3 and not 4.2
