The event queue library does not work with the 1.09 extender. Use either
my patched version (works only if you don't install an EMS driver) from:

   sun.soe.clarkson.edu:/submit/cb_go32exe.zip

       ^ (maybe "incoming" or something similar..)


or the 1.08 extender.

Use the GrSetColor/GrAllocColor routines from either of the libgr.a or 
libgrx.a libraries. Both of these use direct VGA register access to change 
DAC settings.
