  Sorry  for the line breaks, i use opera and IMP under win2000 at work.
  I`ve got no control on this one.

  What the -a switch mean in fbset -a <mode>.  It doesn`t appear in the manual.

  What is DDC?

  Why do the monitor isn`t probed when i used the trick with fbzen and <ctrl-c>?
  
  I use bootX and i need a driver, for mac os 9.1, to use the mach64 or else it doesn`t boot, when the card is in the slot no.:1.  Now it is in the slot.:2 and i can use the computer.  I`ll be downloading a new kernel soon to use the atyfb.

  I tought that an old world ppc could not use a new world kernel!
