Mounting OpenBSD partitions

[Daniel Anson]

I had an old OpenBSD box with some info on it that I need.  I now runn FBSD so my question is this:  how can I mount the OpenBSD disk under FBSD.  The fdisk is as follows:

meddussa# fdisk /dev/ad1
******* Working on device /dev/ad1 *******
parameters extracted from in-core disklabel are:
cylinders=232581 heads=16 sectors/track=63 (1008 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=232581 heads=16 sectors/track=63 (1008 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
sysid 166 (0xa6),(OpenBSD)
    start 63, size 234436482 (114470 Meg), flag 80 (active)
        beg: cyl 0/ head 1/ sector 1;
        end: cyl 1023/ head 254/ sector 63
meddussa# 

Any help would be appreciated.
