Kurt, there's no reason to get aggro. As I have explained to you in the past, the DMA hack (as applied to my board and several others independently some years ago) had the effect stated. I was asked to test the hack on my board and I had the same results as others - (one) Voodoo 3 PCI graphics card would not work in the 66 MHz slot after the hack.

Others have confirmed it since, but I'll leave it to them if they want to speak out. Admittedly, I have not retried the experiment since 2004 (?) and changes to U-Boot since then may have changed the result.

Clearly our experiences differ, and I don't attempt to explain the differences. It may be that some people with hacked XEs have success like you and some have failure like those owners that I know of.

Yep, the A1 "fix" stops PCI graphics cards working, and its also the same reason they don't work in the micro (AFAIK). If it still works for you, well, you're really lucky.

OK! Now I remember! I found an old thread of mine from like update 2. UBoot did not ever see the card, OS4 did but would not give any screenmode options. For some odd reason That thread shows on my recent post list, but the 80 some odd that I posted since then (with 1 or 2 exceptions) are not on the list. lol. Odd, yet it set my memory straight so I really can't complain.

Mine is also listed as AGP 8x but it works just fine in the XE.

I have also had a Radeon 8500 in there and a Radeon 7500 which gave me sometimes no video output or had seating problems. These all vanished with the 9250.

I don't have a fixed XE nor have I ever tried to use a PCI graphic card because what is the point with an AGP slot being there.

But I did read about problems after the fix was applied. Also, this fix is on the MicroA1 and AFAIK it is also the reason for the PCI graphic cards not working there.

I don't think there is much point in unfixing the micro since you then need an active riser card so you can add a SATA or PATA controller card and a video card. This is not going to work since riser cards also don't work.

So this is not a bluebunny rumour it is a real problem.

Changed a noisy 8500LE to a new & cool 9250 with more memory etc. For hyperions sake;) this was a good change, sold the old "fast" one. At the same time changed the core voltages and the processor a few times, all working, hope somebody has a working one in Norway still... Only 933MhZ now. Bought a NX8800 GT overclocked for the must to have pc to play games and do the work. Some thought that the Miga was a game machine;)

Writing with OS4, Looking forward to OS4,1 with some upgrade path. Ehem, price?

was a problem with the base 8500 chip set on board.

I got serial port debug info stating that an unimplemented x86 instruction was in the AIW-8500-DV BIOS during post. It even said which one it was, though I no longer remember. I mentioned it to the powers that be, but didn't seem that anything ever got done to fix it. One particular board may nto be important enough for that amount of work. Other AIW boards went fine. I have an AIW7500 and I know someone with an AIW9800.

Don't worry an 8x card will work fine in a 2x slot.

I tried a card I inherited from my son. Can't remember the details, but it was a Radeon model which should have worked. I think it was a 9800, which is what I had been using until the fan (and chip) burned up. This one just had more memory and a bigger fan.

Anyway. . . when it wouldn't work in my A1, I tried it in my wife's Athlon64 windoze box. Again , no display.

Tried it in my daughter's windoze box. Worked great!

Someone else in this thread mentioned voltage differences in the later 8x AGP boards. I assume that's the problem??

Will I finally be able to use my Ati All-in-wonder Radeon 8500dv card with OS4.1?

I have one such card that refuses to work at all on my Pegasos 2, I've come to a conclusion that it's not "voltage compatible" (even when it does have both keys)

Of course that doesn't apply to all 8500 models, but apparently some are not following the standards. And I guess the same problem would appear on A1 aswell.

-EDIT-

After reading further, you actually got graphics from the card. That obviously means there's no voltage problem (in which case you wouldn't get any picture at all)

I have this model:

Note that it may require some extra cooling. I had to use a fan (12cm) in front of it to have it working reliably. But it could be my SE and its usual problems...

Well, yes, in theory, but:
The manual for Articia says" PCI 66/33MHz, 3.3V with 5V tolerance I/O, and further: AGP 2X Bus Interface", but the slot is universal"


The gfx-card needs to have an universal key (3.3V, 1.5V (and in newest ones0.8V) ), otherwise you will risk to fry the card (and in worst case, the mobo too) if you insert a 1.5V or 0.8V into the A1 generic 3.3V slot.

The problem is, the A1-agp slot is 3.3V only, so it is dangerous to put a 1.5V gfx-card into it.
The problem with this is that the A1 has a generic agp-slot, and cards that should not fit into a standard AGP 1.0 slot can be placed into it without problem.
Normally a real AGP 1.0 slot is used, preventing errors inserting a gfx-card with wrong voltages.

Another problem is the gfx-cards, like with Radeon 9600.
According to ATI itself, the Radeon 9600 can do both 1.5V and 3.3V.
So far so good, but, the gfx-card manufacturers does "cheat" too, so not all Radeon 9600 cards can do 3.3V.
The same with some other Radeon models as well.

In short, the problem comes from both MAI (who used a generic agp-slot) and the gfx-card manufacturers (who does not always follow agp-standards)-

A 9800 should work, I have one too. No 3D (yet) but that is in the works.

What may be a problem with the 9800 is the power supply. It /at least mine) needs an additional harddisk power connector plugged into a socket on the board. If the slot you have it plugged in does not deliver enough power, it might not work; if it does, it might work without the extra plug.

My card has one of these gargantuan coolers on it that look like a vacuum cleaner and sound about the same too.

interesting . . . "in the works"

Well, I just found a 9250 on ebay, so it should work according to the ATI web site.

The first 9800 I had, which burned up when the fan died, had a floppy drive style plug for added power. That ran for about a year in my XE. This second one, which doesn't want to work, is an HIS brand, with the vacuum cleaner style cooler on it, too.

Both were given to me by my son, so I can't really complain. I should have my 9250 in a week or so. The A1's current 9200SE will go to my wife's PC.

Thanks for the continuing work even though the court case drags on.

Paul

thats right my 9800 needed the extra power to work too

Guys this is majorly confusing. I have a XE G4. How do you tell from the descriptions on ebay which 9250 AGP to use? I need a chart with recomended manufacturers. I definitely want the 4.1 and the right card ready to use. Can anyone clearly recommend a generic allround safe choice?
Thanks,
John Paul

@cope

Go to [url]http://www.playtool.com/pages/agpcompat/agp.html[/url]

The have a good description of the differences along with pictures to show where the "keys" are on the card edge for the various AGP standards.

Paul

sorry, AWeb doesn't work with the quote and url buttons and I don't remember the syntax

Whilst we are looking around the web for Radeon 9250 cards will this one work OK from ebuyer (in the UK)? They have over a hundred for sale at a very cheap price. They are a Sapphire Radeon 9250 8xAGP with 256MB RAM
