JMicron ones (or at least some chip models) have issues with VIA 686B and Intel ICH4 based IDE ports. (there may be others) Oherwise, they work well. I've had trouble using the Jmicron bridges with the Promise PDC-20630 based VLB controllers, which was disappointing because it's been the fastest …

Has the PC industry ever actually done any forward planning of the "we are going to include thingy X that's useless today because Microsoft is going to roll out Windows Z in 6 months that runs happier with X" kind? .... Generally speaking, I would say it's the other way around - the PC industry …

I checked the raw disk image and it produces the same warnings, so I'm glad it's not something I "added" to my backup back in 03. Certainly the most interesting VLB driver that I've seen so far! After getting the explanation about how it works, it seems to be more of a copy protection scheme than a …

But soldered, no socket. Would the 170MHz RAMDAC give some additional modes? Anyway I am not going to desolder the existing RAMDAC, so upgrading is not an option. Can you post a picture of your board? If there's a socket for a new ramdac, there's probably a way to disable the one soldiered on your …

Don't really think it needs driver. It's probably just to add some additional/proprietary functionality, since the card is jumper-based. It might have the 32-bit Win3.x drivers on the disks, though. Turns out that the driver has some effect on performance. I got the best throughput performance out …

I would recommend using a socket 370 intel 815 board. I agree, the socket 370 & intel 815 board is probably the way to go. It's the sweet spot for AGP at x4 with a 133mz fsb processor. I have a 440 BX system. It's nice & compatible and I needed 3.3v AGP . Curiously, it works with up to 768MB MB of …
