Well, I was referring to the OBSD MBR partition (of type A6) (aka BIOS partitions), a' la fdisk(8). Maybe a bit unclear on that. So, basically, I wondered if it would be possible to extend MBR: ||A6 partition..|Unpartitioned|...| OBSD: |.|wd0a|..|wd0f| into MBR: ||A6 partition|...| OBSD: |.|wd0a|..|wd0f|wd0g|wd0h|...| /Alexander

I added a second primary A6 partition in the freespace of the same disk using fdisk, but cannot figure out how to use disklabel and newfs properly to add this new partition and then mount it as /var/www/htdocs. In general, we don't support two A6 partitions. Having said that, there is nothing preventing you from partitioning it as something else (say.. um, MSDOS-16, or... some other non-descript number), and then using disklabel to use that space (I forget the command that let's you edit the label with out-of-bounds portions). Not necessarily recommended, will void your warranty, and you could loose data... --Toby.

Just edit the A6 partition to have a new end where you want it. --Toby.
