Perhaps you mean IRIX 5.3, the last 5.x,  which ran on Indy, Indigo, 
Challenge, etc, or 6.4 which was an early special for the Octane and 
O2000/Onyx2.  There's no IRIX 5.4, at least, not released.  It went from 
5.3 to the very short-lived 6.0.1, then 6.2 (Indy, Indigo2, etc) 6.3 
(first release for O2) and 6.4 (ditto for Octane, Onyx/O2K) and quickly 
to 6.5 across the product line.
