Well, completely wasted evening. Night, even.
I did try to test a video card on a HP slimline to compare to the integrated video using XP, but I had a completely weird series of problems with a previously tested card that went all the way down to having to reinstall XP.
When I tried to set up the audio drivers, the drivers would not install because the Microsoft Universal Audio Architecture driver was missing. HP didn't have the driver and said to get it from Microsoft. Microsoft didn't have the driver because they dropped the standard. Even better, when they made SP3 they made it incompatible with the driver. So basically MS literally sabotaged this hardware for future use.
There's supposed to be some kind of whack hack patch somewhere but I may just rip out the best parts and run it over a few times. It's too bad because I love these tiny form factors, and everything but that seems to work... I hate to give up on hardware, especially getting rid of a smaller machine in favor of a larger one when I'm trying to reclaim space.
One of the things I ran into over the weekend was incompatibilities in different systems with different cards. I had like 7 PCI, AGP, and PCIe cards that would not post (beep errors) and 5 of them worked on different systems. Compatibility is largely a suggestion, it seems. At least the "dead" ISA card was just a mystery configuration issue, don't have enough of those to lose one.
Edit: I got the HP s7620n sound working by not following the directions and trying random crap. Of course. I'm not even sure the hotfix patch even made a difference, just ignore the warnings about UAA and install a generic chipset driver for the sound chipset.
Anyway, I did 3DMark99 (not really best for this time but to compare to older cards I tested this weeknd) and the Radeon Xpress 200m, which had a Passmark score of 23, had a 3DMark99 score of 11,486. The 8400 GS (installation of which was craaaaazy) has a Passmark score of 128 and a 3DMark99 score of 3996.
That makes NO sense at all. The only thing I can think of is that the 200m offloads most of the work to the T2600 CPU and the 8400GS does it all on the card? The 200m is supposed to be worthless and yet here I am. No, the scores weren't reversed, the 200m was tested without a card in the system.
I have a second 8400 GS, but it has a PCB post sticking down on the bracket end of the card for no adequately explained reason that interferes with a cap just past the end of the slot.
