ATI M1 progress.

I made a little progress today.

I learned how to build a copy of my vgabios and build a new image rather 
than use the one that came pre-built with the kit.

I've found a configuration that under both ADLO and direct IDT will 
actually enable a VSYNC.  No video output yet but at least its a start. 
    I almost didn't catch it.  It appears to be hung but after about 15 
seconds or so something times out and the familiar *foush* of the 
monitor kicking out of powersave can be heard.  Elfboot then runs and 
boots up my system.

The vgabios emulator still chokes on the image though.  The unsuported 
write string call somehow causes the bios to execute a halt.  Is there a 
way I can set up a breakpoint and then drop to single stepping?
