Will have to talk with the machine owner. The system was intended to
run software from Bruker (sp?) Scientific (NMR analysis) and I don't
know that they are supporting anything other than RH Enterprise, which
is a problem as this is Fedora. Not that sticking with SGI would help
as the license fees for the drivers for any of the higher end tape drives
is rather expensive (though it runs the Bruker stuff well).

What am I looking at ?

[root@fuji dev]# ls -l  /sbin/lsmod
lrwxrwxrwx    1 root     root            6 Nov  6  2003 /sbin/lsmod -> insmod

[root@fuji dev]# file /sbin/insmod
