I didn't learn this till too late, so maybe it will save some other
unsuspecting soul. If you upgrade a 4D/25 to a 4D/35 it has to be
running 3.3.2. Maybe unsuprisingly, it can't be upgraded from 3.3.3 as
a 4D/25 and will not run the 3.3.3 tape as a 4D/35 (this is from the
hotline, not an empirical result).
We had a gl bug on our VGX supposedly (but not really) fixed in 3.3.3.
Given our policy of trying not to find incompatabilities between minor
releases I brought 3.3.3 up with no difficulty on our 4D/25s (with 4D/35
upgrades on the way). We also use rdist from the 340 to keep our system
sources in sync, so different releases are a bother.
I tried to bring it up on our 4D/35, but the recommended 3.3.2 inst
tool wouldn't do, but fool that I am I didn't listen to the software
and instead called the hotline, who first recommended using the inst
tool that came with the upgrade, but luckily called me back before I
actually did this and said that the 3.3.3 tape just doesn't run on the
4D/35. Also, I would have to revert the 4D/25s to 3.3.2 before
upgrading them.
So know you know.
Mark.

Yes, this is a side effect of the timing of the two releases. SOME of the fixes (those that seemed appropriate, and were done early enough) are already part of the 4D35 release. For cases where the bug fixes don't affect files that are on the 4D35 tape (try 'versions long 4D35' to get the list) you should be able to install them. Because some of the files on 3.3.3 might overwrite files on the 4D35 tape, you should probably re-install the 4D35 tape AFTER installing 3.3.3, making sure that you do a 'set neweroverride' first. Note that this is definitely NOT something we would recommend (installing 3.3.3 on a 4D35), just a comment on what would need to be done. The 4.0 IRIX release has full support for the 4D35, so there won't be a 4D35 product in that release. There may be a maintainence tape for the 4D35, containing support for the audio hardware, and maybe (I don't know) some of the 3.3.3 changes. It depends on the timing with 4.0, etc. As usual, these are only my opinions, not official SGI statements...
