Display Arc/INFO Binary Grid does not work correctly?

[Wolfgang Qual]

Hello again, list.
I just created another map, just to test whether I am able to put
Arc/INFO GRIDs on the mapserver. However, all I get is a black picture
(colour information seems to be lost)
-->
http://dream.lrrl.arch.tu-muenchen.de/cgi-bin/M3.cgi?&map=rastertest.dfo.map

The mapserver is compiled with gdal-support, gdalinfo on the rasterfile
produces this information:

wqual at dream:/data/fis/klima/therm_98/grid> gdalinfo ab82s_grd/
Driver: AIG/Arc/Info Binary Grid
Size is 6080, 5520
Coordinate System is `'
Origin = (4449996.875000,5352003.125000)
Pixel Size = (6.25000000,-6.25000000)
Corner Coordinates:
Upper Left  ( 4449996.875, 5352003.125)

Upper Right ( 4487996.875, 5352003.125)
Lower Right ( 4487996.875, 5317503.125)
Center      ( 4468996.875, 5334753.125)
Band 1 Block=256x4 Type=Byte, ColorInterp=Undefined
   Min=1.000 Max=30.000
   NoData Value=255

Is there a way to get the colour-table information into the mapfile?
What is the best way to integrate GRID-files into mapserver-maps? Do I
need the "info" folder (created by ArcView) on the webserver for
displaying the rasterfile correctly?

Thanks again.

Wolfgang
