Elbox Mediator 4000Di MKIII PCI lockups

[Leon Besson]

Yo! bromigos!

Any Mediator A4K MKIII Di 3.3v owners out there?

Long story short. Sent my A4K off to have a recap with a trusted Bromigo.

All cards working at the time which consists of;

PCI 1 = Soundblaster
Zorro = x-surf 100 + RapidRoad usb
Zorro =BigRAM +
PCI 4 = Radeon 9250 128MB

System has a Blizzard Cyberstorm 060/PPC + CVision card.

Amiga OS 4.1FE Update 1

With any PCI card fitted Amiga 4.1 system hangs on Purple Screen.

If you use any Zorro-III card then Boots fine

Have tried reseating the Elbox and played around with the jumpers on the CPLPD card.

Jumpers before;

Master = on/closed

Swap = off/open

Winsize = off/open

Have tried;

Master = off/open

Swap = on/closed

Winsize = on/closed


Also tried 3 different PCI RTG cards. 1 x 128MB Radeon, 1 x 256MB Radeon and Voodoo 4.

Any ideas?

Thanks Mangs!

There are several reports of "purple screen" being down to issues with the ROM.

Did you change your kickstart ROM at the same time?

No. Still using the same 3.1 A4K ROM.

Even when trying to do a fresh install with 4.1 boot floppy and CD it sticks at the purple screen, so know it’s not a corrupted SD/HDD issue either.

Going to try and build a quick 3.1 install with mediator setup and see what PCIINFO shows just to make sure I’ve not got a CPLD issue on the PCI side.

[Leon Besson]

Well the plot thickens….Just tried booting off a good known working 3.1 install disk and the system goes into a reboot cycle… Although the ROM screen shows on power up.

Looks like I need to strip the system down and recheck connections..

[DarrenHD]

Ok, so before you sent it off it was working fine?

Are you sure maprom is disabled in the CSPPC menu (hold ECS down while booting).

[mech]

Are the roms seated well? maybe a bent pin under it?
If you have another set of roms or old 3.0 roms try them and see if a basic 3.1 floppy boots?
as for mediator, reseat the cpld chips in the bridge,could be bad socket contact.
i've seen some bridge cards finicky between the zorro and pci slot,you might clean the contacts on the bridge card.

[Leon Besson]

Thanks Mangs!

So I’ve made some progress. System stripped down, cleaned contacts. Tried replacement ROMS. Still the same issue. Changed the ROM speed jumper from 200ns to 160ns.
ROMs are the EPROM Cloanto types. Then had a look into the 3.1 issue. The Commodore 68040 Library in Libs: was the culprit for the Guru Software 80000004 error. As soon as I renamed it to .old system came to life.
I also reflashed the Cyberstorm to 44.71 and defaulted the SCSI2SD rev 6 with 32GB to default and re-programmed that back with ID and settings.

Now It appears I have a fresh canvas with a fresh basic 3.1 workbench.

Next I plan on installing MMCDV2 Mediator files with the Mediator Daughter board fitted. Zorro-III side appears to be working as the BIGRAM+ 256MB is showing up as FastRAM.
Fingers Crossed the PCI side co-operates.

Will report back.

Hey there! I have a similar build I haven’t yet assembled and configured. I plan to use 3.2 ROMs. I’m happy to try to reproduce the issue you’re seeing if you’d like, just let me know how to proceed.

[Leon Besson]

So. I managed to install Picasso96, MMCDV2 and the MMUP2.6 on 3.1.

When running “PCIINFO” I’m getting no joy

Tried 1 card after another and PCIINFO shows 3 PCI slots as “UNKNOWN”.

Put jumpers as all closed. I even got a defective card issue when adding in the BigRAM plus

The system was working before I sent this off.

All CPLDs are securely in place.

Looks like it’s a new mediator

Are you putting together a 1200TX system? If so the A4000 Mediator is different as it has both Zorro-III and PCI slots

Yep MapROM definitely disabled. System will boot in 4.1FE without any PCI cards installed using the CVision card for display

Nope! I have an A4K with a Mediator and cards new in box.

Is Elbox's vendors.txt file in your S: Directory?

Will check it out Bromigo!

The only worrying thing is, that pciinfo only shows PCI 1 to 3. Yet I’ve placed RTG cards in PCI 4

Feel free Bromigo!

I’m using the following;

PCI 1 = Soundblaster
Zorro 2 = X-surf100 + RapidRoad USB
Zorro 3 = BigRAM+
PCI 4 = Radeon 9200 or 9250 or Voodoo 4 RTG

Jumper setting on mediator control board;

Master = closed
Winsize = closed
Swap config = closed

Have also tried;

Master = Open
Winsize = open
Swap config = open

Also tried;

Master = open
Winsize = closed
Swap Config = Open

[Leon Besson]

So Vendor.txt is in S:

PCIINFO only shows;

PCI 1 and PCI 2

Vendor ID= $FF02

vendor = Unknown

Although I only have 1 card in PCI 4

[DarrenHD]

I was involved in beta testing OS 4.1 Classic. I can state that we were not able to test all combinations of cards in the Mediator in conjunction with Zorro cards. That means you could have address space issues or other problems.

But if you say it was working before, then it must be something else. You could try the recommended card order (see OS4.1 Classic FAQ - lots of good info in there.) Try eliminating cards. We did not test the BigRAM as it wasn't out at the time, but we did test ZorRAM cards (very similar I believe).

[DarrenHD]

One more thing, you could turn on serial debug and use the debug kernel. Save the output to another machine connected via serial cable. That would tell us what's going on on the OS4 side.

I have an Amiga 4000D with a CS MK II 060 and a Mediator 4000D - the newer 3 volt version. I am using a Radeon 9250-256meg, Spider USB, and a Lan card. I have 2 versions of the Bigram 256 (2016 and 2019 I think) and neither one of them works with the Mediator daughter board. Both versions of the Bigram work fine in my other 4000D with the original C= daughter board. Both of my 4000s have a rev 11 buster.

Thing is Mang! I’ve not just added the BigRAM plus, these cards were all working in AmigaOS 4.1 before sending off for the recap

So know these all worked before
