2. Make the following modification to the file
/dev/MAKEDEV.d/TPS_base. Note: This modification is
not required on systems running IRIX 6.4
Locate the area of code which deals with DAT Drives.
This starts with:
*Drive?type:*DAT*
Insert the following before or after the similar entries for
other supported devices:
*Device:*Python*PRTNO*) # DAT drive with
compression
mdev=`expr $mdev + 8`;
mknod ${prf}$1c c ${C_TPS} $mdev;
;;
Note: TPS_base is a script, not a C source file. Use of
the C comment characters, /* */ and // will cause the
MAKEDEV script to fail and device drivers will not be
created. Always use the shell comment character, #, in
this file.
3. Rebuild the kernel, as described below.
See the beginning of this chapter for information on
changing the Inquiry string and replacing PRTNO with the
number applicable to your drive.
Rebuilding the Irix Kernel
1. Once the modifications have been made, you will need to
rebuild the kernel. This can be done using the autoconfig
command ( see the autoconfig man page for details ).
Alternatively, Irix 5.3 and later will detect the changes
made and automatically rebuild the kernel the next time
the system boots.
2. Once the new Kernel is built you will need to reboot the
system again to bring the changes into effect.
