My Quicksilver 2002 doesnt like MorphOS

[Gulliver]

I have recently come across a PowerMac Quicksilver 2002 and decided to give it a try with Morphos.

My setup:
Quicksilver 2002
256MB RAM
PATA HDD 80GB (Unpartitioned, tested working on another machine)
ATI gfx card
PS2 keyboard & PS2 mouse thru a PS2 to USB adapter
Morphos 2.7 properly burnt on a cdrom
I have a samsung 43" LCD TV that is connected thru VGA cable to the VGA port of the Ati gfx card in "PC compatible mode".

When I boot up the MOS cdrom starts and gives me this message:

Quark/Openfirmware
console failed
System: Rev <>
CPU0: Version 0x8000 Revision 0x201
CPU0: CPUClock 799999998 BUSClock 133160004

Then the screen goes black, some more cdrom activity is heard and my monitor yells unsupported resolution. And there ends my MOS experience with this PowerMac.

Can anyone help me figure out how to make it work?

[Gulliver]

Thanks, will do that and report back

Okay, thank you, it worked, after changing the montior to another one. I am posting this from the default OWB1.1 which will soon be updated to 1.9.
The thing is that my Radeon 7500 (32MB) seems to only manage upto 1024x600, and then again this "new" monitor wines about it saying that I should better use 1440x900 resolution, which seems unavailable to me from MorphOS

Is there a way to tweak the settings to make it work in that optimum resolution? At 1024x600 my eyes hurt, but at least I can see the entire desktop.

BTW I am usiong now an 19" LG model M198WA-BM

Any help is apreciuated.

[Gulliver]

Thank you again Piru. I am trying right now with the service manual of the monitor to manually configure the "Monitors" preferences.

I guess you should see that the DDC code gets reworked, since both of my LCD monitors work beautifully with the Quicksilver on both on OSX and Linux

I know the MOS experience is much better than this unfortunate monitor incident, that I am confident I will manage to solve with your help.

I will post back hopefully in a couple of minutes with a happy smile.

Update:

I went to Prefs->Monitors and selected New, then changed 8 bit to 24 bit. I raised the pixelclock till the upper end so that I that I could achieve higer resolution modes.

On Horizontal timing, by reducing the sync and pulse length I managed to achieve 1440 (which was my goal here).

On the Vertical timing despite tweaking the values I could not achieve anything higher than 624 resolution (900 is my goal here).

I am clueless

This are my monitor resolution values taken from the Service Manual:

6. RGB Input (PC)-M198WA
No Resolution H-freq(kHz) V-freq.(Hz) Pixel clock(MHz)
1 720*400 31.468 70.08 28.321
2 640*480 31.469 59.94 25.175
3 640*480 37.5 75 31.5
4 800*600 37.879 60.317 40.0
5 800*600 46.875 75.0 49.5
6 1024*768 48.363 60.0 65.0

9 1280*1024 63.981 60.02 108.0
10 1280*1024 79.976 75.035 135.0

12 1440*900 55.935 59.887 106.50
13 1440*900 70.635 74.984 136.75

@Kronos

I started with a Samsung series 4+ 43" lcd TV PDP450, that didnt work with MorphOS from the install cdrom. It just showed some console failed message for a couple of seconds, and then nothing. Optimum resolution is 1024x768.

Then I switched, as suggested by Piru to another one, an LG 19" lcd model MW198WA-BM, which is the one that I am speaking about, that doesnt seem to work either at its optimum resolution of 1440x900.

And, as said before both support DDC and work beautifully under Linux and OSX on the same hardware (QS2002).
And they both work great with any x86 PC compatible I tried.

[Gulliver]

They were both always connected to their VGA input, directly from Radeon 7500 VGA output on the QS. From VGA to VGA with no adapters in between.
