2.Edit the file /dev/MAKEDEV.d/TPS_base and make the following modification (this modification is not required on systems running IRIX 6.4 or 6.5).

Locate the area of code which deals with DAT drives. This starts with:

*Drive?type:*DAT*

Then insert the following text before or after the similar entries for other supported devices:

*Device:*DAT*06240*) # DAT drive with compression

mdev=`expr $mdev + 8`;

mknod ${prf}$1c c ${C_TPS} $mdev;

;;

Alternatively, you could manually rebuild the kernel using the autoconfig command (see the autoconfig man page for details ), then reboot the system again to bring the changes into effect.
