What have you done with a PowerPC today?

Audio works? Also, what download do you use for tiger server universal?

It works even on Tiger client, I just got to test it there.
Caveat: supported audio formats are not as extensive as your ffplay, I did identify a video in my collection that played audio with ffplay, but not with mplayer 1.5. But for most things it played audio no problem

Mac OS X Server 10.4 - Macintosh Garden

Macintosh Server software 10.4 (Tiger) This is the first release of Tiger Server. Like public version, it comes in DVD or CD forms. Intel based Macs are only compatibles with the version 10.4.7 (6th DL above from the top of the list).

I forget which download for Tiger server on that page, but it was one of those. Tiger server universal has pretty minimal benefits over Tiger client, having used both on different machines for a few months.
There was a runtime crash in Chatty on client that didn't happen in server. Server seems to have modestly better gl support. Other things (like getting classic working) are more of a pain. And the sleep control panel doesn't work correctly, though forcing sleep by closing the lid is good enough for me. YMMV, but imo client should be the primary reference system, especially since server universal is G4/G5/Intel only.

So this is a dual 2ghz early 2005 with 4 slots:

Ok, sounds like the 256s are not compatible. This is what the service manual for your machine says about RAM. Note how the slots should be filled etc.
