Hi,

bought MorphOS, running it on a PowerMac G5 and most of the times when I start up, MorphOS runs very slowly. Let's say the clock gets updated all 8 seconds and I see mouse movement also in these intervals. But it doesn't always happen.

Any advices?

Greetings,
André

Also, it feels like some interrupt problem since it doesn't happen steadily in this interval. After it tooks 3-4 minutes to show the full desktop, the mouse can be moved very slowly but for like 1-2 it's fluent. Strange.

This is most likely related to some graphics card setup problem that I figured out recently. Is the related PowerMac G5 graphics card a ATI Radeon9800Pro/XT card ?
There is no immediate fix/workaround for this problem. It will hopefully be fixed for all setups once MorphOS 3.3 is released which isn't too far away ...

Yep, it's a Radeon 9800 XT with dualhead output. Okay, no problem. Current workaround is rebooting some times to be able to work normal =p

And if you need someone to test, msg me here =)

Any chance of MOS breaking the 1GB ram barrier for G5?
I'd like to see 4GB.
Thanks

1 GB may be probably improved to 1.5 GB, the same as for G4 machines. But anything beyond that will require MorphOS to go 64 bits. It may happen in some unspecified future, but there are no fixed plans.

I thought the limit for 32bit operating systems was 4GB.
Why is it 1.5gb for MOS?

Is that an old OS 3.1 limit?

Some OS-functions use negative return values as error codes (positives are addresses), limiting the safely useable addressspace to 31Bit (2GB).

In this limited space one also has to fit all PCI/AGP cards and onboard components for which another 512MB of addressspace is reserved. For some reason this seems to have grown to a full 1GB on the G5s.
