The re boot sequence is:
BIOS screen and then
Darwin /x86 boot v 5.0.132 - Chameleon v1.0.12
Build date xx xxxx
2047 memory
VESA v2.0...16mb ATI RADEON 9600 PRO
Press any key for boot options...
Loading Darwin x86

Then it jumps to a black screen the machine beeps then back to the initial BIOS screen,


I have tried the -x boot option, and I think -xf, but no options seem to get i out of the loop.

Here is the spec using lspci -nn.

Thanks

Neil
