Kyro/Nforce incompatible?

[Mark R]

Been itching to try my new NF7 - but my old G200 won't fit in the AGP slot, and my Radeons have not arrived (and are now not expected for ages).

So, I went to the local shop and bought a cheap Kyro2 card (Hercules Prophet 4500) for testing, with the plan to ebay it when finished.

Trouble is - it doesn't work properly. In Win2k, device manager reports a conflict on the NVIDIA Nforce2 PCI to AGP bridge' and therefore it is not possible to install the kyro drivers.

A google search reveals numerous people with the same problem - but never a solution.

Is this a known incompatibility?

Nope, like the Voodoo cards the Kyro is a 3.3v card. NForce only takes 1.5v AGP cards.

No, that's not it.

My G200 is a 3.3V only card - and like all 3.3V only cards it cannot physically be inserted into a 1.5V only AGP slot.

The Kyro2 card I have is definitely dual voltage. It works fine (using it now), I just can't install the drivers, because Windows can't install drivers for the AGP slot.

No, some AGP video cards *did not* adhere to the AGP slot standards, so they fit in slots they shouldn't. The early P4 mobos had a problem with non-compliant Video cards(3.3v only) frying things on their 1.5v only AGP slots. The 2 types of cards causing the problems? Voodoo's and Kyro's(for the most part).

Your G200 properly does comply to AGP standards, so it doesn't fit.

The reason your card seems to work is that it is currently in VGA Compatibility Mode. Windows won't allow you to install the drivers likely due to the BIOS notifying Windows not too, to do so would cause damage to the motherboard or video card.
