FreeBSD can't see OpenBSD slice

[Saifi Khan]

Hi:

I installed OpenBSD 3.5 in a 25GB slice on a 160GB SATA HDD.

Now when i power up the system and boot into a FreeBSD
instalation CD (8.x 200902 snapshot), the Fdisk partition editor
shows the entire disk as unused.

Are slices created with OpenBSD tools not seen in FreeBSD ?

thanks
Saifi.
