This is the Main Slice (``FDISK'' or PC-style Partition) Editor.
|
|
|
|
Possible commands are printed at the bottom and the Master Boot Record
|
|
contents are shown at the top. You can move up and down with the
|
|
arrow keys and (C)reate a new slice whenever the highlighted
|
|
selection bar is over a slice whose type is marked as "unused."
|
|
|
|
You are expected to leave this screen with at least one slice
|
|
marked "FreeBSD." Note that unlike Linux, you don't need to create
|
|
multiple FreeBSD FDISK partition entries for different things like
|
|
swap, file systems, etc. The usual convention is to create ONE
|
|
FreeBSD slice (FDISK partition) per drive and then subsection this slice
|
|
into swap and file systems with the Label editor.
|
|
|
|
No actual changes will be made to the disk until you (C)ommit from the
|
|
Install menu or use the (W)rite option here! You're working with what
|
|
is essentially a copy of the disk label(s), both here and in the Label
|
|
Editor.
|
|
|
|
If you want to use the entire disk for FreeBSD, type `A'. You'll be
|
|
asked whether or not you wish to keep the disk (potentially) compatible
|
|
with other operating systems, i.e. the information in the FDISK table
|
|
should be kept valid. If you select the default of `Yes', slices will be
|
|
aligned to fictitious cylinder boundaries and space will be reserved
|
|
in front of the FreeBSD slice for a [future] possible boot manager.
|
|
|
|
For the truly dedicated disk case, you can select `No' at the
|
|
compatibility prompt. In that case, all BIOS geometry considerations
|
|
will no longer be in effect and you can safely ignore any
|
|
``The detected geometry is invalid'' warning messages you may later
|
|
see. It is also not necessary in this case to set a slice bootable
|
|
or install an MBR boot manager as both things are then irrelevant.
|
|
|
|
The FreeBSD slice will start at absolute sector 0 of the disk (so that
|
|
FreeBSD's disk label is identical to the Master Boot Record) and
|
|
extend to the very last sector of the disk medium. Needless to say,
|
|
such a disk cannot have any sort of a boot manager, `disk manager',
|
|
or anything else that has to interact with the BIOS. This option is
|
|
therefore only considered safe for SCSI disks and most IDE disks and
|
|
is primarily intended for people who are going to set up a dedicated
|
|
FreeBSD server or workstation, not a typical `home PC'.
|
|
|
|
The flags field has the following legend:
|
|
|
|
'=' -- This slice is properly aligned.
|
|
'>' -- This slice doesn't end before cylinder 1024
|
|
'R' -- This slice contains the root (/) filesystem
|
|
'B' -- Slice employs BAD144 bad-spot handling
|
|
'C' -- This is the FreeBSD 2.0-compatibility slice (default)
|
|
'A' -- This slice is marked active.
|
|
|
|
If you select a slice for Bad144 handling, it will be scanned
|
|
for bad blocks before any new filesystems are made on it.
|
|
|
|
If no slice is marked Active, you will need to either install
|
|
a Boot Manager (the option for which will be presented later in the
|
|
installation) or set one Active before leaving this screen.
|
|
|
|
To leave the slice editor, type `Q'.
