How to use edlabel
|
||
|
|
------------------
|
||
|
|
|
||
|
|
|
||
|
|
Edlabel is a program to edit disklabels on any disks in a standalone
|
||
|
|
environment. Mostly it is used to set labels when doing initial
|
||
|
|
installation procedure. It is started from boot program prompt.
|
||
|
|
You will here be guided through a session, things with ^^^^ under
|
||
|
|
is typed in by the user, comments are within /* */.

With this program you can modify everything in the on-disk
|
||
|
|
disklabel. To do something useful you must know the exact
|
||
|
|
geometry of your disk, and have ideas about how you want
|
||
|
|
your partitions to be placed on disk. Some hints:
|
||
|
|
The a partition should be at least ~20000 blocks, the
|
||
|
|
b (swap) is depending on your use of the machine but it
|
||
|
|
should almost never be less than ~32000 blocks.
|
||
|
|
|
||
|
|
Disk geometry for most DEC disks can be found in the disktab
|
||
|
|
file, and disknames is listed in the installation notes.
|
||
|
|
|
||
|
|
Remember that disk names is given as disk(adapt, ctrl, disk, part)
|
||
|
|
when using the installation tools.

This program does not (yet) write bootblocks, only disklabel.
|
||
|
|
Remember to write the bootblocks from the miniroot later with the
|
||
|
|
command "disklabel -B <diskname>".
