Where did you set that option bytes? The command used to import
georeferenced tif files is r.in.gdal, in the GUI (assuming that you
use wxGUI and GRASS 6.4.2) available under File -> Import raster data
-> Common import formats. I could not find an option "bytes" for

In order to be able to help, it is necessary to know what command you
used, what GRASS version, what GUI, preferably also what operating

Helpful would also be the output of gdalinfo on the tif file.
