I compiled a custom kernel with the root path hard coded to sd0a, put that on the CD and then it worked. I think it's an OK workaround until IBM fixes the uEFI problem. Did a simple dd with bs=1M count=1024M. SSD IDE write = 175MB/s AHCI write = 250MB/s Pretty significant difference.

OpenBSD 5.2 AHCI problems with IBM x3250 M4
If I enable AHCI mode in UEFI/BIOS and boot from the cd52.iso, the installation finds the disk (sd0) and I can setup everything in fdisk and complete the installation. However when I reboot, the system can't find any operation system. It works if I change it to IDE mode, but I don't want that. VMware ESXi 5.1 installs and boots just fine with AHCI mode. I'm trying to figure out if the problem is with OpenBSD or my hardware as the x3250 M4 runs UEFI and I guess has some sort of BIOS emulation. I've tried 5.3 snapshot with the same result. Any pointers? Thanks!

Any pointers? Thanks! 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.
