/dev/rsd0a

[uid0-obsd-misc@catastrophe.net]

I'm setting up a box to dual boot obsd 3.1 and XP (Don't yell at me,
I just need XP for my Garmin GPS mapping software).

I install obsd fine, but when trying to build a .pbr as per the 
instructions in the FAQ, the following happens.

  # dd if=/dev/rsd0a of=/tmp/openbsd.pbr bs=512 count=1
  dd: /dev/rsd0a: Device not configured

Any assistance is appreciated. I allocated the whole disk to OpenBSD 
when in fdisk. This prolly isn't the most wise idea as I'll need to 
go back and redo it, eh?
