yes, it could be obtained through the Developer Program (I have a copy), 
though I seem to recall some strings attached.

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.
