After my MacMini was collecting a lot of dust in the last year I was starting to play with MorphOS again for the last week.
I installed MOS 3.9 and Chrysalis pack 3.9.4 and still had a lot of freezes with MOS.
So I decided to look more deeper into HW and SW from my user point of view.
Starting with HW:
1.) Apple Hardware Test running with extensive test of RAM and checking other HW.
-> all test OK
2.) Using memtest of MOS to check RAM with extensive test (with loop of 30)
-> all test OK
3.) Using memtest of MOS to check Video-RAM with extensive test(with loop of 30)
-> all test OK
4.) Open Up MacMini and remove all dust, even if there was not much.
=> Maybe there is still a HW issue(?), but for the next steps I assumeed HW is OK and all issues are from SW.
Play with System and Software:
1.) In the system option: "Enhanced Display Engine"
-> "double buffer", "tripple buffer" and "balance" was all three active
-> I disable all three options step by step.
-> This makes my system hell more stable (!) and faster (!). No more crashes when switching screens or using OWB.
(I allways enabling this options after fresh install in the past wrongly assuming this will show better grafic. But it only needs too much of my 64MG grafic memory. Maybe there is a bug in the ATI driver then memory is too full? With disabling the options my system use less grafic memory and runs more stable now.)
2.) I activate System Error Log in the Screenbar to track errors better.
-> I found a couble of errors in the system log right after a fresh boot, comming from "AHI/c.audio", "AudioModes/ENVY24HT" and "Classes/Screenbar/Mousemeter.sbar"
-> I disable them by moving them to SYS:Storage and reboot.
-> Now my system boots allways with a clean system log (Sound still works, ENVY24HT was not needed).
3.) Only one applications still tent to freeze my system very often after running it and causing errors in the sytem log too.
-> Hurrican 188.8.131.52_rc2
-> One of my favorite games. While playing it ther is no problem, but after closing it the system log is full of errors
and when using system with other programs this leads very often to freeze the system. When I not use the game there are no freezes.
4.) A few more programs show strange errors in system log, but none of them causes system freezes so far.
After those steps my system runs more stable now even with multible screens, a lot of SW open(e.g. Mplayer showing a movie from my NAS) and surfing with OWB. It runs now over hours stable untill I decide to make a shutdown.
I will have a look into system logs in future for all programs I running to see if they are causing system logs and maybe also an system freeze. Using MOS without freezes makes more fun while using it. Hopfully at one day MOS will have an memory protection to have a rock solid system and finding all the buggy SW.
