FAT partition names

[Jeff Wyman <wysoft_(_at_)_wysoft_(_dot_)_tzo_(_dot_)_com>]

I'm feeling pretty stupid right here right now after using OpenBSD 2.8
on i386 for the first time and trying to mount my FAT partitions.
Previously, I had them mounted with FreeBSD by specifying /dev/ad0s1 to
mount a FAT32 partition at the beginning of the disk. Now I've replaced
that with OpenBSD and I can't seem to find what partition to use to
mount my FAT partitions on it :(

I see entries in /dev for wd0a,b, etc. but they are BSD disk labels.
"fdisk -r wd0" sees the two FAT partitions on my drive. Any clues on
what device they might be?

thanks
