During installation, you have the option of controlling the layout
of partitions manually. This option is called
Interactive disk setup.
NOTE:
Each version of fdisk
is documented in the respective operating system's manual.
Unless otherwise noted, SCO documentation refers to the
UNIX system version of
fdisk(ADM).
fdisk is interactive, and uses a menu to display your options:
1. Display Partition Table
2. Use Entire Disk For UNIX
3. Use Rest of Disk for UNIX
4. Create UNIX Partition
5. Activate Partition
6. Delete Partition
7. Create Partition
Enter your choice or 'q' to quit:
You can do the following using fdisk:
Reserve separate
areas (partitions) on your hard disk for different operating systems.
The hard disk is divided into tracks.
The number of tracks depends upon the size of the hard disk.
A partition consists of a group of tracks.
Each hard disk can accommodate four partitions.
Specify one disk partition as ``active''.
This means that when you turn on (boot) your computer,
the operating system installed in
the active partition will start running.
The UNIX partition must be active when you intend
to use the SCO system.
Specify
the number of tracks assigned to each partition.
The number of available tracks will vary according
to the size of your hard disk.
Consult the Release Notes for the recommended
UNIX partition size.
The size of the UNIX partition also depends on the number
of software packages you want to install.
You can install the SCO system in this space,
and have the rest of the space for user files and
other software packages.
Refer to the
custom(ADM)
manual page for information on how to install and remove software.
Specify precisely where the partition begins and ends.
fdisk will not allow you to construct overlapping partitions.
You do not need to install the SCO system in the first partition.
You should start your DOS
partition at the beginning of the disk, starting at cylinder 0 or
cylinder 1.
If you install a UNIX partition on the same disk after
the DOS (or extended DOS) partition,
start the UNIX partition at the beginning of the next
cylinder on the disk.
To find the beginning of the next cylinder,
note the ending track number of your DOS partition and start
the UNIX partition on the next track number that is a
multiple of the number of heads on your hard disk. For example, if you have
five heads on your hard disk and your DOS
partition ends at track 103, start your UNIX partition at track 105.
When you are running the SCO system, the device name
of the active UNIX partition is /dev/hd0a.
For more information about hard disk device names, see the
hd(HW)
manual page.
