Please note that this page is for older video cards: AGP-based for PowerPC systems.
There have been several things that have bothered me when trying to upgrade Mac systems:
– Apple seems to hate supporting old hardware.
– Devices made for Apple computers seem to cost up to ten times what they do for PC, even if they use identical hardware or even slower components.
– Third party support usually comes from un-reliable sources. People that can’t keep a website up, people that lose interest in helping the community, and those who are greedy that try to keep the money-saving (or potentially money-making) information to themselves.
I will be putting some ROMs/firmware on my site to help others with flashing video cards for Macs.
I have flashed a few PC video cards for use in Apple Macintosh systems.
XFX “WANG” GeForce 6200, 256 Megs RAM, $49 from Newegg.
– Requires 10.4.3 or higher. You will get a Kernel Panic if used in an older version.
– Uses a Temp Sensor that can cause long boot times under Mac OS X 10.5.x if you use it on a G4.
– There is a special firmware that disables the temp sensor.
– Supports Quartz Extreme and Core Image
VisionTek 5564 GeForce 2 MX 400 64MB SDRAM AGP DualHead/TwinView, $5-$20 from eBay.
– Works great in Mac OS 9 and all Mac OS X versions.
– Supports Quartz Extreme
This worked in my G4 Mac with the original PC/Windows firmware, however:
– The mouse cursor was a solid “box” when using Thousands/Millions of colors (it looked fine in 256-color mode).
– The system couldn’t detect my monitor or its timings, so resolutions and refresh rates were a bit off.
– Things worked perfectly after flashing with the “1075 TwinView” ROM.
* Update, August 2008: I noticed in World of Warcraft that the sky looked like it was filled with artifacts – like the card has bad memory. After staring at the messed up looking sky, the system had a kernel panic and locked. :(
* Double update. It turns out the wrong timings were in the firmware. Default MX400 timings are 200/183, default MX200 timings are 175/166. The VisionTek card uses 200/166 timings. I modified the firmware and re-flashed, and everything is good now. :)
Elsa GeForce 2 MX 400, 32 Megs, $5-$20 from eBay
– So far has worked great.
– No issues in any games.
– No artifact/memory issues.
– Flashed the NV1100 firmware, 200/183mhz timings.
ATI Radeon 9700 Pro, OEM, 128 Megs DDR. $30 from eBay.
– Quarts Extreme and Core Image support.
Inno3D GeForce 2 MX 200, 32 Megs, 64-bit SDR, AGP – “Tornado GeForce 2 MX-200″, purchased for $45 brand new back in 2001.
* NVFlash said the EEPROM wasn’t flashable.
* Some random GeForce 2 MX 400, 64 Megs, PCI – Unknown brand, NVFlash can’t identify the EEPROM.
The EEPROM wasn’t the “non flashable” kind on the Inno3D GF2MX200, it just wasn’t listed as a supported EEPROM by the version of NVFlash I was using.
Recently, I haven’t been able to get the card at work at all (PC or Mac). I think I killed it with static or something. :(
GeForce 2 MX firmware:
nv1075(twin).rom (what I originally flashed on my VisionTek 5564 TwinView, but has the wrong timings for that card)
VisionTek 5564 ROM (200/166 timings, TwinView support, based on NV1100 ROM)
GeForce 6 firmware:
xfx_6200.rom – Original 350/266 MHz. (what I flashed on my 6200)
xfx_cube.rom – Cooler running 300/250 MHz.
MLP256XFX2_NoSensor.rom – 350/266 speeds, but with temp sensor disabled (for Mac OS X 10.5 compatibility).
Radeon 9700 Pro:
visiontek_5564_original.rom – My original VisionTek 5564 TwinView firmware for PC.
xfx_6200_original.zip – My original XFX “WANG” GeForce 6200 firmware for PC.
For my TwinView:
nv312.exe -f 1075.rom -m
For my Elsa:
nv312.exe -f 1100.rom -m
For my 6200:
nv513 -4 -5 -6 -j 6200.rom
