Hi Pigseye,
I also have a BE6-II 2.0 with a 600MHz Celeron o'clocked to 900, and I've been experiencing some problems with video. I bought a Pinnacle Systems DC10 Plus video I/O card to acquire and edit video, but the playback is jerky; every 2-3 sec or so the video freezes for a fraction of a second and then jumps to where it's supposed to be. I've tried many things, and have posted on the Pinnacle Systems forum to see if they can help. I know the hard drive is fast enough to stream the video -- even the Pinnacle's hardware test program says I've got speed to burn. The most maddening thing is that I can get the software to stream a perfectly smooth video program on my 3 yr old Dell XPS-D266 PII 266 MHz with ATA33 Maxtor drive!
I had heard of the Highpoint ATA100 controller having difficulties with Maxtor DiamondMax drives, so I set it up with an IBM Deskstar and Quantum fireball, both ATA100. Today, I heard that the controller has trouble with Deskstars! However, it's doing the same thing with my Quantum and with a Maxtor I threw in there to test, so I don't think it's a hard drive issue.
I'm using the ATA100 controller for both my hard drives, but the same jerky video happens if I run them off the slower primary IDE channels, too. I just downloaded the latest BIOS version (BERVI) and plan to flash it this evening to see if it makes a difference. If not, then I'll try disabling the ATA100 controller and install a Maxtor (Promise) ATA100 controller to see if that makes any difference.
If it isn't being caused by the on-board controller, then I'm afraid there must be some sort of bottleneck inherent in the board that's causing this video glitch, or some BIOS setting I need to tweak.
Have you come across anything like this? Any ideas or suggestions are welcome!
