Some old programs I wrote in 2003 for my PPC PowerMacs:

XClaim Enabler for PPC PowerMacs

This application enables support in Panther for ATI XClaim video cards which do not
normally work. It works by making Panther load the NDRV driver on the video card rom.
It 05- or 05- not work for you.

Please note there are issues with this fix. It doesn't appear to work with XClaim VR
cards. Be sure to write down the following should you get in trouble!

To fix the patch if you get stuck:
You can undo this by power cycling the machine and holding down command-option-OF which
will drop you into the openfirmware prompt.
Then type
setenv boot-args="" <enter>
and then
mac-boot <enter>

mac-boot 05- not work and if it does not. just hit the reset button and let the machine
reboot. The boot-args setting will still be intact even across the reset or a power
cycle.
