OpenBSD on a VAXstation 3100 M76

I picked up a bunch of DEC gear last weekend:

• VAXstation 3100 M76
• VAXstation 3100 M38
• DECstation 5000/200
• Storage expansion unit
• VR290 colour display

The M76 has three disks installed currently, configured VMS 5.4. I wanted to leave these as they are, without modifying them, and installed OpenBSD 5.8 to the SCSI storage expansion.

The easiest way to do this is to write the cd58.iso image to the disk you want to install it to, from another computer with a SCSI card. You can then boot off that and perform a network installation. Now I can boot from either VMS or OpenBSD.
