input-device can be set to 'kbd' as this seems to be a standard alias,

however, with output-devices we are not so lucky (on newer Open Firmware

versions, 'screen' usually works).

 

Machine                output-device

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

PowerBase              /bandit/ATY,mach64_3D_pcc


PowerCenterPro         /bandit/ATY,mach64_3D_pcc


PowerWave              /bandit/ATY,XCLAIM


9500 old Mach64        /ATY,mach64 


7200                   can't output to monitor at all


7300, 7500, 7600       /chaos/control


7300 w/ATI XClaim3d card (should work for this card on any PCI Mac) -

                       /bandit/ATY,XCLAIM3D@D


8500, 8600, 9500, 9600 varies, depending on the video chip that the 

                       machine shipped with.  Try /bandit/ATY,XCLAIM 

                       or /bandit/ATY,264VT. Newer 9600s ship with a 4Mb

                       IXMicro TwinTurbo; try 

                       /bandit@F4000000/IMS,tt128mbA@F


StarMax 5000           /bandit@F2000000/ATY,RAGEII_M@11


Also, Paul Mackerras provided this suggestion: 

'If you know the PCI config space address of the card (this will be a hex

number between B and 1F, depending on which slot it's in) you can use a 

name like /bandit/@11 (say). I guess you could try all the addresses in 

turn.'



If you have a second computer handy, you can try finding it out the device

using it to talk to Open Firmware - see the /LinuxPPC/OpenFirmware category.

Not too difficult (when you know), but it took me several months to realize
why my ATI card in my 9500 PowerMac won´t display the OF:

It has two PCI busses.

so, you have to specify the second bus for identifying the output device:

output-device pci2/ATY,mach64

I mixed the above with Paul Mackerras' "try all addresses" suggestion.

On my 9600/300, which has an 8MB TwinTurbo, the following works:  pci2/@F
If your card is not in the same slot as mine, I guess one of the following
should work:
/bandit@F4000000/IMS,tt128mb8A
/bandit@F2000000/IMS,tt128mb8A
                            ^ note the "8" between "mb" and "A"
