I am not experienced in how many and what types of filesystems BSD supports. From my expereience Linux can support many filesystems and, as a Linux user, I would simply rebuilt the Linux kernal to support the filesystem I need to mount (in this example, the filesystem used by SCO).

For linux:

Code:

Usage: fdisk [-l] [-b SSZ] [-u] device
E.g.: fdisk /dev/hda  (for the first IDE disk)
  or: fdisk /dev/sdc  (for the third SCSI disk)
  or: fdisk /dev/eda  (for the first PS/2 ESDI drive)
  or: fdisk /dev/rd/c0d0  or: fdisk /dev/ida/c0d0  (for RAID devices)
  ...
www# fdisk /dev/hda

The number of cylinders for this disk is set to 9964.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

   t   change a partition's system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit

Are you sure of the filesystem type of the hard disk you want to mount?

partx

PARTX(8)						      System Manager's Manual							  PARTX(8)

NAME

       partx - telling the kernel about presence and numbering of on-disk partitions.

SYNOPSIS

       partx [-a|-d|-l] [--type TYPE] [--nr M-N] [partition] disk

DESCRIPTION

       Given  a  block	device	(  disk  ) and a partition table type , try to parse the partition table, and list the contents. Optionally add or
       remove partitions.

       This is not an fdisk - adding and removing partitions is not a change of the disk, but just telling the kernel about presence and numbering
       of on-disk partitions.

OPTIONS

       -a     add specified partitions or read disk and add all partitions

       -d     delete specified or all partitions

       -l     list partitions. Note that the all numbers are in 512-byte sectors.

       --type TYPE
	      Specify the partition type -- dos, bsd, solaris, unixware or gpt.

       --nr M-N
	      Specify the range of partitions (e.g --nr 2-4).

SEE ALSO

       addpart(8), delpart(8), fdisk(8), parted(8), partprobe(8)

AVAILABILITY

       The partx command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
