Use of atidump:

First call "xatitv -v" to locate the ATI Register Aperture address:

PCI card @ 0:16:0: ATI 3D Rage IIC PCI (Mach64 GV):
==> FrameBuffer @ 0xEC000000, Registers @ 0xEFFFF000
                                          ^^^^^^^^^^

... or find it in the X server output:

(--) Mach64: PCI: Mach64 Rage IIC rev 58, \
Aperture @ 0xec000000, Registers @ 0xeffff000, Block I/O @ 0xde00
                                   ^^^^^^^^^^

Then split the register aperture address in two: 0xEFFFF000
becomes 0xEFFF and 0xF000 (upper and lower half).

Then call atidump (in windows :-) with the upper and
lower halves of the register aperture address as args:

atidump 0xEFFF 0xF000

The register dump is written (appended)
to file atidump.out in current directory.


To enable I2C traffic window in ATIPLAY:

Create an ativideo.ini in C:\windows\system (if it's not there),
then put these two lines in:

[I2CBusDriver]
debug=yes

When you start ATIPLAY, an extra window
should then appear, showing the I2C traffic.
