The current 2@800x600_60 and 2@800x486_30i sdb files that are shipped
with patch 1447 do not work correctly.  The blue information is
missing from the screen.  The tar file impact_ico_sdb.tar contains new
versions of these sdb files and associated files to drive the display
correctly.  This tar file also makes a minor modification to the
2@1160x960_30qi, 2@1024x946_30qi, and 2@880x808_30qi formats.  The
rising edge of vertical sync was slightly mis-aligned.  The problem
was not visible on any monitors tested, but is corrected none-the-less.

The tar file should be installed after patches 1406 and 1447.  Please
install 1406 and 1447 first.  Then, to use this tar file, become root
and down-load the tar file to /tmp/impact_ico_sdb.tar.  Unpack this
file using the command:

	tar -xvpf /tmp/impact_ico_sdb.tar

This will install a new version of the sdb files and associated files
to drive the 2@800x600_60 and 2@800x486_30i formats:

/usr/gfx/ucode/MGRAS/vof/cmb/FPGA/fpgas.two.rbf
/usr/gfx/ucode/MGRAS/vof/cmb/2@800x486_30i.sdb
/usr/gfx/ucode/MGRAS/vof/cmb/2@800x600_60.sdb
/usr/gfx/ucode/MGRAS/vof/cmb/2@800x600_60_ext.sdb

Files replaced to update the 2@1160x960_30qi, 2@1024x946_30qi, and
2@880x808_30qi formats:

/usr/gfx/ucode/MGRAS/vof/cmb/2@1024x946_30qi.sdb
/usr/gfx/ucode/MGRAS/vof/cmb/2@880x808_30qi.sdb
/usr/gfx/ucode/MGRAS/vof/cmb/2RSS/mgras_two_1025x946FS_mco.sdb
/usr/gfx/ucode/MGRAS/vof/cmb/2RSS/mgras_two_1160x960FS_mco.sdb
/usr/gfx/ucode/MGRAS/vof/cmb/2RSS/mgras_two_875x808FS_mco.sdb

After the new sdb files have been installed, the X server must be
restarted in order to use the new files.  This can be done with
the following command:

   /usr/gfx/stopgfx; /usr/gfx/startgfx
