So far I have confirmed the official Nvidia driver packages 71.84, 77.72 and 81.98 do have support for PCI-E GeForce 6800, 6600 and 6200. The problem is, it is necesary to skip the installer and to select the card manualy, when istalling.

NV40 GeForce 6800 - I was unable to test it
NV43 GeForce 6600 - Works very well with 77.72 and 71.84. The 81.98 comes with shutdown problems.
NV43 GeForce 6200 - The initial release of the 6200 came from degraded 6600 chips - untested but should work.
NV44 GeForce 6500 - no entry in the inf section, support unknown
NV44 GeForce 6200 - I'm not sure if all the PCI-E 6200 NV44 came with the Turbo Cache function. In any case these do not seem to be working correctly.
NV44a, NV44a2 GeForce 6200 - I do not know if they are available in PCI-E versions. According to my research they should be just in AGP and PCI versions.

I've been testing the cards on HP DC7100 with Intel 915 chipset. But, I did not test the 3D functions.

I'm curious about:
- Do the official Nvidia packages provide support for the NV40 and NV43 chips with PCI-E? Or perhaps it is possible to use the NV44 as well.
- Are there NV44 PCI-E 6200 cards without Turbo Cache?
- Are there NV44a and NV44a2 PCI-E 6200 cards?

Informations gathered:
- NVidia GeForce 6200 cards with Turbo Cache are not working correctly in Windows 98 with both official and unofficial drivers.
- Nvidia official driver support ends at GeForce 6800. Compatible Hardware with Windows 9x
- The GeForce 6800 NV40 chip is the oldest one from the GeForce 6 series. The newest is NV44 61xx,6200,6500. The NV43 6600 is clearly supported in the official Nvidia drivers. Wkipedia - GeForce 6 Series

I have an update, as I was able to test a Gigabyte GV-NX66128DP (PCI-E GeForce 6600) with HP DC7100 (Intel 915).

There is support for the GeForce 6800 series in Nvidia 61.76 driver package, however there is nothing about the 6600 series.

After testing 77.72, 71.84 and 81.98 driver packages, it appears the system restart function works correctly in all of them. System shutdown works good except for 81.98. The computer ended with "it is safe to turn computer off now" like message, so I had to turn the power off by myself.

In all three driver packages I did experience problems with running DOS applications. There was a dialog informing about an "illegal operation performed by the application" or complete loss of video function in full screen mode. The workaround is to change the screen color depth at least once after booting the system. The DOS applications are seeming to work correctly, after that.
