Is it trivial? This is where I use xmon. There is a macos version at (I think) ftp://ftp.linuxppc.org/users/paulus/misc/xmon.bin. From memory, the control registers are at 0x90010000 and the RADACAL (ramdac/cursor chip) registers are at 0xf301b000. The other thing to do is to browse through the darwin sources from apple and see if they have a control driver somewhere. IIRC, the hardware cursor uses some extra bytes on each scan line and some registers in the RADACAL. Paul. [[ This message was sent via the linuxppc-dev mailing list.
