[UPDATE]

I've had limited success with the AGP versions. Apparently they are also Rage 128 GL variants, but with 16MB of ram over a 128bit bus. I've managed to flash a bios file from VGAMUSEUM MKIII from a 16MB 128GL AGP card and the MAC card I flashed now posts. The DVI port does not work, and only 8 out of the 16MB of vram is detected, and only at 64 bits. The ASIC number is different for the BIOS I flashed as well.

So basically the AGP cards need a video bios from an SDRAM card with 16MB over 128bit.... all the SDRAM Rage 128 GL PC cards in my collection are 64 bit...

As you can see the card posted and installed as an Xpert 2000 under windows XP. It ran quake 2 with the default XP driver, scoring 29.8 FPS at 640x480.

Anyone own a rage 128 GL AGP with 8 memory chips?

Is there a way to modify the existing bios files or the stock roms?

Win9x and Rage3 gets more Quake2 640x480 fps than Rage128 (Rage4) in XP. I dont know whats good OpenGL for XP, but for Win9x and Rage128 (use OpenGL 1274).

Yeah it's pretty slow. Almost Voodoo 1 slow...

On topic - I figured out what the problem is - the cards are 16MB / 128 bit. All of them, PCI or AGP... The PCI cards will not output an image with the All in Wonder Rage 128GL bios, but they are detected correctly. The bios reports 32MB despite the card having only 16MB.

The AGP cards work with the 16MB bios, but that bios is taken from a 64 bit card, and only half the ram is detected... somehow.

Is there a bios editor for ATI cards that suport the Rage4? Something like nibitor is for nvidia... I'm wondering if I can mod the bios files I have to get these cards working.

For Radeon sure is, Rage cards have some flashing tools, but editor for Rage3 i have not seen, for Rage128 maybe.

Thank you. I don't understand what the author of the text file is trying to say - using a translator yields sentences that make little sense, but I'll try the files included in the archive.

My cards are 16MB 128 bit, hopefully those BIOS files are for 16Mb cards as well.

Unfortunately none of those BIOS files in the mac to PC page worked for me, neither for the AGP or the PCI card. For starters most files are the wrong size, another that is the right size and ASIC type is corrupted (checksum error). The rest do not work.

I have made more progress with the AGP cards - I've been able to find a 16MB BIOS file that makes the AGP version PC compatible. I've even tested in Quake 2 3.24 @ 800x400 with a 550Mhz pentium 3 it gets 40 fps. The Bios is clocked 112Mhz for both ram and core.

Here is the file that worked for me in case anyone else wants to flash the AGP 16MB 128bit Rage 128 GL to PC:

This file also makes the PCI version post, but it will display a black screen. It's detected in windows and the driver installs fine when used as a secondary card, but when enabling it it still gives a black screen at any resolution.

I'm still hoping to get the PCI cards to work on PC. Does ANYONE have a PCI Rage 128 with this layout?

What utility could I use to edit Rage128 / Rage4 bios files?

[UPDATE]

I read the MAC PCI Rage 128 GL has a 128kb flash rom... the BIOS files for the PC versions are 32 or 64 kb in size.. Is it possible ATIFLASH 1.6 isn't correctly flashing / completly flashing the EEPROMs on the MAC PCI cards, causing it to not read correctly at POST?

If that's the case, desoldering the 128kb EEPROM and soldering one a 64 or 32kb module form a pc rage 128 card then flashing the Xpert 2000 or generic PCI Rage 128GL ROM might work, right? I have a few parts cards, I could try this approach. Another way might be creating a custom 128kb rom file that has only the first 32kb of data and the rest all ffffffff or 00000000 might also work.

I'll try and post my results.

Rage3 ATiflash works only up to v1.5, cant remember what was best from 1.0 to 1.5, v1.6 did not work for older cards.

Here older ones and 1.6 also here.

1.6 worked fine for me so far, but thank you for the link!

I've made further progress:

- I've taken the EEPROM (AMTEL AM49F512) from a very low end looking OEM Rage 128:

-Soldered the donor EEPROM to the MAC Rage 128 PCI:

LEFT - modded card with 64kb EEPROM ----- RIGHT - unmodified MAC Rage 128

- Flashed all the PCI EEPROMs I have gathered so far, witch is only 3 roms...
- The card posts only with the All In Wonder Rage128 rom taken from TheRetroWeb - this file:

but there is a catch.... My LCD monitor reports "non standard settings" message. I think the card is outputting 61hz, but have no way to make sure. I'll hook it up to a smarter display and check. Then it got worse. In Quake 2, the card set some refresh rate that my LCD did not support. When the LCD went "out of range" I hooked it up to my 21" IBM CRT and that displayed just fine, and it didn't complain about the refresh rate. I fixed this by capping all resolutions to 60hz with Rage128 tweaker. The card installed fine under win98 with the rage128 drivers I had on hand as an 'All in Wonder Rage 128". I think the drivers I'm using are from 2002, I got them from a thread on this forum. I also installed rage128 tweaker. One issue is that several AIW devices show up in control panel:

I disabled the devices of course, since this is not a real All In Wonder card so there's no TV tuner.

It runs Quake and Quake 2 just fine. problem is it tries to run 76hz or 81hz out of the box, so my LCD will go nuts when running quake 2. Works fine in GLQuake.

A good 100% conversion would require a rom from the PC version of this card. The rom on TheRetroWeb doesn't work, it's probably for a 32mb card, or it has some other issues.

I'm still looking for a tweaking utility or some way to edit the roms... gut the rom to remove the AIW parts so they won't show up in device manager, correct the display output frequency, and adjust the clocks. Right now the card runs at 92/92MHz.

Still, I got 1 of 3 PCI cards working on PC, and it's going right into my Pentium PRO rig.
