If you like working devices I'd advise against buying a system board with an nVidia chipset. I picked up an Asus K8N-E some time ago, but my on-board audio, gig ethernet, video and some other miscellaneous devices didn't work under OpenBSD 3.8. I have yet to try a current release; maybe this weekend. Was the problems with seagates OBSD related, or general to the HDDs? I've had nothing but good experience with seagates so far, quiet, fast and cheap. The newest I have is in 24/7 use, and has been for the past year or so... ISTR there being some bad runs of Seagate drives a few years ago, maybe that was the problem? I have a small Seagate drive from maybe 2000 that's worked without issue. I've been buying Maxtor SATA drives these days. The first thing I'd need to know is there any real gain from dual core's on OBSD (I think they do work, but how well?), if there's a real performance gain using dual cores then I'm probably going with dual cores and need to find out if there are some chipsets that work better, or more importantly if there are chipsets that don't work at all. Also I'd like to know if there's improvement on amd's 64bit vs 32bit. I think this is really going to depend on your application. If none of your processes are threaded, you're probably not going to see a big performance gain by going multi-proc. Likewise, a 64-bit CPU will give you more memory bandwidth, but if you're not using it what's the point? If you use any binary device drivers, you'll want to check that they're available for your specific platform. And of course if there's some knowledge about running software RAID (SATA) on OBSD, how much it takes CPU, what kinda speeds people have gotten with it, etc. Btw, better to keep these thru the misc mailing list, in case somebody else needs similar info. - turha -Damian
AMD dual core, deciding factors for a platform?
Hi, I'm about to build a new box, and thought I'd ask first if there's any experience with AMD's dual core processors (AM2 or s939). From what I've read both socket types work as amd64, with bsd and bsd.mp, right? Any thoughts on which works more stable and faster, i386 vs amd64 arch, and the benefits of using bsd.mp? What chipsets/MoBos work well? So mainly I'm interested in comments from people who have tested these, to see if it's worth the trouble (money) to get dual core for openbsd, is there much of an improvement, etc. I'm planning on using the box for quite a few things, including software RAID, samba, FW, web server, probably ftp, etc. On a side note, AFAIK there are no working DVB-C cards for openbsd, right? Thanks, - turha

The Intel Graphics Media Accelerator 950 chip would be a nice approach, just to deny nVidia a sale. How you get that with an AMD CPU is unknown. Was the problems with seagates OBSD related, or general to the HDDs? I've had nothing but good experience with seagates so far, quiet, fast and cheap. The newest I have is in 24/7 use, and has been for the past year or so... It worked great in a USB enclosure under 'Doze, after I passed it on. It was a 300Gb drive. I tried a different IDE controller, too. Figured there was some special pixie dust in the Redmond driver. Best, Chris

I just built a friend a new PC around 4.0 release come out so I thought I would try 3.9/4.0, 3.9 bsd.mp wouldn't boot after install so I went to 4.0 and worked just fine. This is running off of onboard NIC, and onboard SATA without problems with a Seagate HD. I hear the e6000 series are faster than AM2s.
