DECwindows: ATI Mach64 on V6.2

The Question is:

I am trying to get an ATI Mach64 graphics adaptor to work
on my Alpha Server 2100 (VME).  When I run sys_exer at the
boot prompt it appears to work just fine (i.e., I get a
continual string of "Digital" repeated across the screen).
However once the machine boots the ATI attached terminal
does not display the expected login screen.  It blacks
out about 1/4 of the screen and the rest has the blue
background that was there from the VGA sys_exer tests.

I called ATI and they said that their card works just fine
in the Alpha Server 2100 without adjusting any of the
jumpers on the card.

I got (via my local DEC guy) the ECO patch AXPGUP01_062 so
that the ATI Mach64 driver would be there.  It installed
without reporting any problems.

I reran AUTOGEN and still it did not work.

I look in the DECW$SERVER_0_ERROR.LOG and it does not say
anything bad that I can see.  These are the last few lines
from the log file:

Any thoughts?

Thank you for your help.

The Answer is:

         1. Configure the system firmware to recognize the MACH64 option.

         2. Install the appropriate patch, if OpenVMS version is pre-7.0.

         3. Make sure SYSMAN is using the proper prefix when searching for
            the file SYS$LIBRARY:DECW$ICBM.EXE.  Note: ICBM stands for
            IOGEN Configuration Building Module
