I don't think I understand. I haven't even tried putting the card in. I got it out of a box of random graphics cards a long, long time ago. Unless you mean the Mac? It's a bummy v1 ROM model found on the first revision Beige MTs.
The Mac has Open Firmware 2.0f1?
Is the GPU for Mac or PC? Does it have an fcode rom? Can you get a dump of GPUs rom? Do you have a Mac serial printer cable that can connect the Beige MT to another computer?
 
The softstraps string starts a ROM offset 0x58 and ends at 0x6b with a checksum byte. This applies to all ROMs Mac or PC. So one way to approach it is to copy it from the BIOS of your card to the Mac ROM.
When the checksum is incorrect the softstaps get ignored, so the card will be set up based on hardware straps (resistors).
To calculate the checksum you have to add all the bytes (exclusive of the checksum itself) together using 8bit precision (i.e. you discard anything above the byte boundary, example: 6f7 = f7) and then negate it (using calculator: your result, Not, +, 1, =) When adding all the bytes together including the checksum your result should be "0".
The string is divided into 4 32 bit numbers + the last 4 bytes that I only know the meaning of the last one - the checksum.
The first one is the AND mask (allows you to set straps to "0") the second one is an OR mask (allows you to set straps to "1") for register 101000 what individual bits mean will follow. The second pair is the same for different set of straps, but I don't know the meaning of it, I'm pretty sure that's the place where you can enable features like pipes for 6800.

@joevt Here is the MDD rom dump.
Thanks. Below is a list of the device fcode images from the decompressed result. The result of the detokenizations are in a different file. And the result converting the detokenizations to Forth is in another file. Let me know if you want any of it.

interesting how its all mostly ROM's from period iBook's and PowerBooks of the time!

@joevt I think I got the dictionary dump correct this time:

BTW did you ever figure how to decompress a 1MB New World ROM?

There are a few FCODE ROM's for video cards only contained in the BootROM I'd like to be able to extract.

indeed I was thinking about this a while back, more specficly regarding the fCode ROM for the iMac G5's video cards

as an iMac G5 internal is DVI and obviously has a VGA port on the back

so the cards are effectively DVI-VGA cards which would match much better with a PC Radeon 9600, then any of the PMG5 ROMs do

and it would be fun to see if a Radeon X600 Pro or X600 XT could be flashed with a iMac G5 iSight's ROM :)

The Mac has Open Firmware 2.0f1?
Is the GPU for Mac or PC? Does it have an fcode rom? Can you get a dump of GPUs rom? Do you have a Mac serial printer cable that can connect the Beige MT to another computer?
I can't check the OF version because I can't get into OF-- the display never fires up when I try invoking it. (I also run into this issue when installing OS X. I wonder if it has to do with the way my display output is configured)
No it's definitely a PC card. It's got the funny s-video out on it.
I haven't the slightest on where the fcode rom would be on the board.
I could probably dump the rom-- I'll just have to pull out my testbench and a board.
Nope, I don't have one of those serial cables.

..... maybe I should just pay the Mac tax and pick up a known compatible card. 😓

I only have Quad G5 ROM. I didn't format the device descriptors like I did for your G4, but unlike the G4, the Quad G5 does have a name for each fcode image. None of them appear to be for a GPU.

I think this thread is for GPUs that are known to work in a newer Power Mac that you want to get working in an older Power Mac.
 
@Doq if you have a PC PCI Radeon 9250 then you will simply just have to flash it with a suitable Mac ROM then it will work in your G3 Beige, you dont need to edit anything to get it working in a G3 beige like you do a GeForce 6200

post a picture of the card and tell me the DeviceID if you can and ill point you to the ROM you will want to flash it with :)

you may also need to remove some resistors about, but im not sure how critical these are!

You got it. imgur.com

I don't remember what the deviceid is, but it's a Diamond 256MB variant if that's any help.

I saw that article too and I'm hoping they're not absolutely necessary (but they might be and I'm not completely confident in my solder skill, especially with components this small).

looks like a fairly standard reference card

I doubt all 256MB will work but if it has a 128KB EEPROM

and if it is indeed an ATI Radeon 9250 DeviceID and all then try flashing it with this ROM http://campahunta.free.fr/Downloads/ROMs/ati_ret_9200_201_pciagp_full.rom.zip

note that due to the different DeviceID you might need to juggle around to find the correct OS 9 drivers for full acceleration but they are on the Macintosh Garden!

ATI Flasher from graphiccelerator in Mac OS X will do you nicely :)
 
on the G3 Beige GeForce 6200 front pleased to report it all works on my Rev B G3 beige :) tis really awesome to see Core Image coming out a G3 beige!

for me it was the PNY_6200_PCI.ROM that worked for my PNY GeForce 6200 (Curiously its a green card so, I did try the green card 6200256.ROM first but while that worked for OF OSX would panic, however the VRAM chips on my card are different then either so I guess the VRAM settings for the Blue card match my specific green card better!)

I'd be interested in these FCODE ROMs, wonder why they are in the boot rom.
 
Thanx for posting the SoftStraps explanation!

But for my PNY 6200 the complete Straps are just copied from the 512MB PC ROM. And so are all portions, which differ from the 256MB ROM. I don't know what else could be done ton "enable 512MB" in the ROM. But it still shows 256 in OS X.
 
Is there even a way to VNC into a Mac, running OS 9? Only way to remote OS 9 i know is Timbuktu. But this needed OS 9 on both sides, as far as i know.
os9vnc works. It has a server part, I just made sure to make an alias that I put in my startup folder to start the server when it booted (without functional video). I used that earlier in the thread on my powertower booting in 9.22. Used my Macbook running Montery with a osx vnc viewer to log into it.

leftovers from the Xserve G4? which IIRC use those ATA chips (and you have to disable them to Boot OS9)

one thing I have noticed over time is that a lot of Apple BootROM's tend to be quite universal in that for a given set of machines from a given generation the BootROM's of all will all have the same components even if in some macs those components are never used

so its quite interesting to see thats true of a PPC ROM too :)

I've included the disassembly and Forth parts. The fcode of the Forth may be machine specific so I didn't include it.

Here's my lzss that is used for the decompression. I haven't worked on the compression part.

Here's the latest version of the tools that are used for producing the dumps or to tokenize the Forth code.

I've updated all the patches at #487

I'll finish the patch for Open Firmware 1.0.5 next.

Has anyone tried the patches yet?

After that I'll look at the 6200 rom for vram stuff.

Can you add a link to the PNY_6200_PCI.ROM that you used? Wondering if it's the original or my patched version or something else.

Yes, i did/do. But not the latest updated version. Will try this later.

If it's of any help in that case, attached are both of the PC ROMs of the PNY 6200s, 256 and 512MB-versions, as well as the Mac-ROM, i am using, which works fine in OS X, but only showing 256MB and showing 512MB in System Profiler when booted to OS 9.

Edit: I don't know, if the 256MB-card, the PC-ROM is for has exact matching PCB-layout, as there are many PNY 6200s. The 512MB version, i have, is this one. At least i know, there is a 256MB-card, using this layout, branded Club3D, i had an fCode-ROM for, which i used to patch for the 512MB-card.

I gave the FW800 MDD patch a quick test with my FW800 MDD and my Quadro FX 4500 (which is a 512MB PCIe card from/for my G5 Quad) but sadly I get the same result as without it, OF hard locks as it attempts to output video to the monitor

(the patch installed into NVRAMRC fine and the system on its own still boots to OF just fine with it in place, so its not regressing anything at least, but the moment I chuck the FX 4500 it all falls over like it normally does)


the ROM I used for my GeForce 6200 and G3 beige, was indeed yours from the zip file 17b :)

If the Quadro FX 4500 is the only card we have that we know works in Mac OS X with 512 MB in a Quad G5 , then maybe we should look at that. Can you post a rom dump or link for the Quadro? Plus dump-device-tree from the Quad G5, and an Open Firmware lspci.

There i can add one. The 7800 GTX 512MB. And it's not even as similar to the Quadro as it looks. Quite a lot more powerful.

Here is a collection of three known working 512MB ROMs: The one for the Mac OEM Quadro, as it is in the Wiki. Another one for a Quadro which has memory chips only on one side. And the one for the 7800 GTX 512MB, which has much higher clocks than the Quadros.

Also i do not know if it could be of any help for comparing things as it's a completely different card, there is a 256MB version of the GTX too. And here is it's ROM, which the 512's should be based on.

Which Quadro ROM do you use?
Are the Quadro and 7800 PCI, AGP, or PCIe? Do you have a method to connect PCIe to PCI?
