OK I guess I have cleaned all the cowebs.

To get an M-Audio USB Quattro working cleanly with JACK, an intel i850
MOBO and an NVidia geforce2.

I had to set a few things.

- BIOS: AGP = 32 MB RAM cache

- Using AGPART (kernel agp driver not NvAgp)

Put this in /etc/XF86Config

Option "NvAgp" "2" # use AGPGART (0=noagp, 1=NvAgp, 2= AGPART)

- Set the bandwidth use from 4x to 2x

Put this in /etc/modules.conf

alias char-major-195 NVdriver
            options NVdriver NVreg_ReqAGPRate=0x2

Reboot.

Now Everything seems to be pretty stable. However I imagine that my
dvd's aren't going to look quite so nice now.

========================================

Being on stage with the band in front of crowds shouting, "Get off! No! 
We want normal music!", I think that was more like acting than anything 
I've ever done.
