You will need to make sure the machine is in plain ol' BIOS mode. Sounds like you have something fancier than anything I've got. :) But... if the system is coming back saying it can't find an os, that is a more basic problem than OpenBSD -- that's a flubbed boot loader install or a BIOS trying to boot from the wrong device. To get the system to try to boot, very little is required -- a partition marked "active" in the MBR, and a valid "signature" (0xAA55), and the MBR code, and the BIOS to try to boot from that. If you aren't getting that, either the OpenBSD installer is freaking out in some really odd way that I don't think we've seen before on just your machine or you did something "odd" during the install that you didn't think was important, or your BIOS is trying to boot off the wrong thing (which I'm currently leaning towards). You can test my theory... boot off your CD, when you get to the boot> prompt, try "boot hd0a:/bsd", see if it boots. If not, try "hd1a:/bsd" and any other "hd*a" that shows up before the boot prompt. If it boots, you have proven OpenBSD is compatible with your machine. If you needed to tell it hd1a or hd2a, then your BIOS is trying to boot from the wrong device. If that doesn't work, boot from the CD in ahci mode, and show us what the output of "fdisk sd0" looks like. Nick.
