Jeff,
Yes, it seems odd, but that is what the Gateway specs say.  I got an earlier message from 
Andy Green on this list saying ( if I understood correctly ) that specifiying a greater color 
depth (24) would work fine because it will only use as many bits as it is capable of.  That i,
just the first 18.

Andy, if you read this, I tried increasing the hsync and vsync frequencies a bit, up to 
71Khz and 79Hz ( up from 67 and 75 ), and that seemed to make no difference.  I am hesitant to 
go higher without knowing what the capability of the monitor is.  Do you have any idea 
how far it is safe to go with the sync rates?


I spent a bit of time browsing the list archives in the XFree86 sections.  For a bit I thought 
that I might have a problem with the BIOS not allocating the full 8M of ram, but the log file 
shows that is NOT the case.  I am going to post my XFree86.0.log file to one of those lists 
and see what they have to say.

Thanks for your help, looking forward to any more suggestions...
