Pleae Help!! how to instal file.tarx

I downloaded a patch, the extensionis tarx. I copy it to / directory. then
i type:
/etc/install -u somefilename.tarx (somefilename is just an arbitrary
name)
it says :
somefilename.tarx.f No such file or directory
pax no input

then i tried:
tar -xfv somefilename.tarx

it says:
tar: blocksize is 20
tar offset[0] no such file or directory.

please help!

I believe that you’re trying to install a QNX4 archive. It must be
installed with the QNX4 photon install utility on the CD ROM.

Also, if you are asking about QNX4, you should ask in the QNX4 newsgroup.
This news group is for QNX6.
