Hello,

My Pegasos is 0.1b114 version.


I've already noticed this issue since I started using Morphos 3.06 and a flat screen. Recently I've installed Morphos 3.15 from CD, in a new partition with PFS3.

In the past I used a CRT with different graphics cards than Voodoo 3 with Morphos 2.x and I didn't have any problem, maybe only with an old 1024x768 flat screen.

Now I have 2 flat screen one is 1080p and another is 4:3 1024p.
If I change Voodoo 3 for and ATI 9200 PCI I got black screen and hard drive does not load anything. Only once it worked with ATI 9200 AGP. In Ambient I had Voodoo configuration working for Radeon (?) then I changed Ambient for a specific Radeon Screen but after restart I had changed graphics card for Radeon 9200 PCI and then again black screen, now I can load Morphos if there's a Voodoo 3!

What's wrong with Pegasos 1 except for Articia S... yes yes I got April 2, ECC ram, but not a CRT around.

Try to boot with both PCI-GraKa! Voodoo and Radeon uses different drivers, which MOS recognizes automatically. If you get a screen on Vodoo you can check prefs/Monitors, wether Radeaon is recognized or not.......
It's a good idea to test this from a new installation or booting from MOS3.15-CD.

That didn't work.
Now 9200P AGP is working as well as 9200S AGP, but 9250 PCI is still not working at all.
Maybe there was some dust inside AGP slot while I also cleaned the 9250 PCI contacts but not working as I wrote.

Do you even see open firmware screen with 9250 PCI?

Are you sure the PCI Radeon is not a Mac variant? These won‘t work in a Pegasos.

As said Amigaharry2, check if Open firmware visible with other cards, or try to boot from installation CD.

Maybe your 9250PCI is 64MB version and your new resolutions is simply too large...

If Open firmware is visible, try to boot to MorphOS bootmenu:
- press "shift" during boot process
- od add parameter "bm" to your boot command

in bootmenu press "v" to toggle resolution

No

I bought with ATI CD, driver are for Windows

Nice commands but Open Firmware is not visible.
All my Radeon are 128 MB while Voodoo can manage 1080p 24bit with 16 MB only. Only the ATI 9250 PCI has 128 bit of memory bus and can still boot from PC. Maybe my Pegasos 1 does not support that card or is witched. The mark of Articia S.

Technical Data says 64-Bit memory bus..... https://www.techpowerup.com/gpu-specs/radeon-9250-pci.c1162
But nevertheless it should work in a PEG1 (I think Peg1 has PCI-5V?), as written in Pegasos-book.
Is this PCI-Card really OK? Have you tested it in a PC ? Sometimes even brandnew cards are faulty.....

Quote:

Yes 5v version, it works on my PC very well and this card had never been used before me..
I made a GfxSpeed: my Radeon AGP are made to work @200 MHz doing only 10% better then Voodoo 3. On Macmini Radeon @250 MHz scored more then double than PEG1. At me looks like PEG1 can't sqeeze even a slow Radeon and so a 128 bit version is useless. Nevermind I can use Radeon on AGP saving a PCI slot.

I don't know if you want to utilize this exact card, but if you are search for speed, I recommend you AGP card Radeon 9800 PRO (chip R350).
It works on Pegasos 2, but I don't test it on Pegasos 1.

R9800Pro works fine on peg1

I had a r7500pci that only worked on peg2b5.

I know people Who had problems initializing r9250 and fixed these with a firmware update

Well, nice to know maybe one day I will change for it...ty

I found another issue. When there is inserted an USB 2.0 PCI card and any Radeon AGP, Peg1 is not able to boot.
But if instead of an AGP card I use my older Voodoo 3 PCI, Peg1 can boot.
I guess AGP can't work properly in my Peg1 togheter with other PCI cards.

I have faced this issue on other -Peg2 not Peg1- machines in the past.

Try a different PCI card or a different slot.

Or find a combo with AGP and PCI cards that would allow the machine to boot.

Can I know which cards do you have?

Never heard that for PEG2! Use since years AGP-Radeon 9200, VIA-USB2-PCI-card and Symbios SCSI-PCI-card without any problems.....
PEG1 may be different........

Quote:

My Peg2 also has Radeon 9200 AGP and VIA PCI USB2.

Well I would not blame the machine. My card may be a little faulty... I do not know. But I had to try different slots in order for it to work, and place it carefully on the lower PCI slot.

Last weird thing I found in Peg1 is if I invert Voodoo 3 PCI and USB 2.0 cards, Morphos can boot but it becomes not really stable then: applications as OWB Taskmanager etc. stop working while pointer can be moved and HD led stays always on as a torch... Did reboot 3 time to have the same results everytime.

Now I remove those PCI cards for a better Radeon AGP card cause Voodoo 3 is fine at 1080p until OWB does not load the wrong page, at that point madre mia so slow...

I also noticed Peg1 is connected at 10 Mbit only when I thought it had to be 100 Mbit.
