Looking for Formac ProMedia 40 ROM Rip

[Phipli]

Morning folks.

Does anyone have a rip of the S3 Virge based Formac ProMedia 40 ROM (or the ProMedia 20, and 80 if they made one!)? Or do you have a card and are willing to extract the ROM?

The card should be capable of RAVE 3D and run a few 3D textured games, although it isn't the fastest. It would be an interesting project to see if we can flash a PC card. I have one on the way (hopefully it works, I'll test it in a PC before experimenting).

The card looks like this :



I'd also be interested if you have any other type of Mac card with an S3 Virge or Virge DX chipset.

Morning @stynx are you able to rip the ROM from a ProMedia 40 for me?

I'm curious if I can flash a generic PC card to work as one and get some cheap RAVE 3D PCI fun. I have one on the way.

It's getting harder to find interesting Mac cards for reasonable prices, but there isn't much love for the S3 Virge

Did any of the Formac cards use the Virge DX?

Everyone else - same goes for anyone else reading if you have a ProMedia 40 or a 20?

That would not be very fun. The Formac Virge driver is not well implemented for Rave and has a lot of bugs.
I have flashed a PC Virge (325)...

Macintosh Garden has CDs from Formac containing many ROMs or drivers. Just search for Formac.

I think this one from February 2002 has 64 ROMs for 17 different products:

I have bought an original Formac ProMedia 20 in 1997 for my Power Macintosh 7200 to use a Belinea 15" Monitor besides the 14" Apple AV monitor. The Rom on that card was revision 1.0.6 which i later upgraded to 1.2.6 that i got from Formac for cost of shipping. I even upgraded the VRam from 2Mb to 4Mb to get moe colors in higher resolutions. Back then i could not get the 3D acceleration to work because the 4.5.0 Version of the GA control panel misplaces the 3D extension in the wrong directory.
When requesting the updated Rom, an engineer from Formac told me that the Virge could easily be overclocked by changing some bytes in the rom. I never bothered since 2D was fast enough. Sadly i lost the addresses for the bytes to change in the rom. I remember that by rule of thumb i was told that if the Vram was
35ns: >= 80MHz
40ns: >= 70MHz
45ns: >= 60MHz
The technician said that they did have a select Virge tested at 100MHz in the lab with 25ns VRam but that typically 65MHz was the limit on commercial cards.

I can probably find the ROM location. The registers of interest are SR10 and SR11 to enter the scaling factors for MCLK and SR15 to enable it.

Annoyingly most of the PC cards have much lower VRAM speeds. Cost benefits are eroded when you start having to buy a card and then buy faster VRAM for it. Perhaps for experimentation I can clock the card down.

The overpriced Formac card on eBay has 35ns VRAM.

Do you happen to know what the default memory clock frequency was on the Formac card?

What speed VRAM is soldered to yours?

Thanks @joevt - I forgot they shared their ROMs on the CDs. I was planning to rummage in the Drivers this weekend because I remember there is a resource that lists all the cards and their chipsets, but hadn't got to that yet.

Answered one of my own questions, looks like Formac ran their cards faster (60MHz) than most vendors even stock :



Well.... It's only a 20% overclock from stock, it might work

Which ROM is ProMedia 20?

If you want to make changes to the ROMs, then you'll want to look at the Forth code. You can retokenize changes into a new ROM with my OpenBIOSStuff.

I have a Open Firmware Extender 2.4 for Beige G3's that have Open Firmware 2.4. Open Firmware Extender loads Open Firmware patches and drivers from disk. It can include Option ROMs for PCI cards that don't have an Option ROM or if you want to override an Option ROM (because it's larger than the flash size or because you can't flash it). Open Firmware Extender 2.4 is discussed in the DingusPPC Discord server. I've included firmware for Formac GA12 card. I'm currently trying to include a patch for LBA48 support for Beige G3's in Open Firmware and Mac OS X. Mac OS 9 already supports LBA48. Open Firmware Extender should be able to include ndrv's for Mac OS 9 and kexts for Mac OS X. I've ported stuff from Open Firmware 4.9.6 (including LBA48 support and HFS+ support) to Open Firmware 2.4 and added some bug fixes and new commands (such as list-partitions). I'll need to add a preprocessor so I can create extenders for other versions of Open Firmware. The preprocessor will add commands similar to #if .. #endif to the scripts and Forth source files so they won't need to be completely duplicated for each version of Open Firmware.

Which ROM is ProMedia 20?

Should be GA-6 : it is a 2MB version of the S3 Virge card.

The GA-3 one is the S3 Vision 986 (I have the Radius equivalent, but not the Formac one).

If you want to make changes to the ROMs, then you'll want to look at the Forth code. You can retokenize changes into a new ROM with my OpenBIOSStuff.

Bleh, I always forget that this era of stuff isn't just a machine code binary. That's a pain. It still might be easier to look for the three parameters that make 60 MHz near mentions of the registers needed to set them.

It can include Option ROMs for PCI cards that don't have an Option ROM or if you want to override an Option ROM (because it's larger than the flash size or because you can't flash it).

That sounds useful for getting ATI Rage XL and LT cards running with less fuss, and some of the IDE cards with embedded flash.

Also nice for experiments without having to dismantle everything!

LBA48

That will be nice, it's a pain having to find small IDE disks when there are hundreds of 500GB disks for cheap on eBay.

I know this is probably a daft question, but is there a more comprehensive resource for OpenFirmware anywhere? All I have ever found are partial lists of common commands. I can navigate, modify NV stuff and poke around a bit, but I've never seen a "Learn how to make an OpenFirmware Forth Driver in 12 easy steps" book or anything similar.

Also, I'm getting strong "you need to go and grab one of your Beige G3's" vibes
