i've got openbsd 3.0 running on my primary laptop, a dell latitude cs. this is a pretty good laptop ... very light, long battery life (4+ hours), decent keyboard. the only problem is that there are NO serial ports (no infrared, but I don't care so much about that). if you feel that you'll be needing a serial port, buy the port replicator when you buy the machine, it's much cheaper that way. everything is working including the sound card (from 2.7 onwards) ... it's an integrated chipset into the NeoMagic 256AV.

this gets the display going at 1024x768, 24bpp. looks *very* nice. i'm using an old dayna communicard 10mbit card, as well as the 100mbit port in the docking station.

also, a lucent wavelan 802.11b card from, for wireless use around the apartment.

Second laptop I have is a Micron Millenia Transport. It is a P133 that I have running as the Wavelan 802.11 gateway. Ethernet in the docking station for the uplink, 10Base-T PCMIA running NAT for one segment, and Lucent Orinoco Gold Wavelan card for a second wireless segment. Here's a copy of the dmesg output.

I was very excited to see support in OpenBSD 2.9 for the builtin SCSI chipset (pcscp) from the docking station. Once I find a terminator for my old CD-R I will try it out.
