You need to do some reading on the BIOS settings of the 1850. There is an option in there where you can switch from SCSI (mpt) to RAID (ami) mode and back. The trick is that it requires a so called "RAID key" for this functionality to work. This is a purchase option; don't know if you bought it or not. 1850s work fine with OpenBSD 3.8.

We have a Dell 1850 with a PERC4/DC controller. When I try installing OpenBSD 3.8, I am having some troubles. 3.8 will sees the card as with the mpt0 driver. Which will not recognize my RAID1 config. The hardware compatibility guide tells me the mpt0 is support for a standard scsi card. According to the hardware guide, the correct driver for RAID support is ami. When I boot with the, boot -cs and add the ami driver support, I get a no disk drive support.
To check the drive config I installed and booted another OS.  Any
help/comments would be greatly appreciated.

Thanks
