<b>How to Use gBootRoot</b></P>
|
||
|
|
<P><IMG ALT="" SRC="images/gBS.jpg" align="right">The most important button to
|
||
|
|
familiarize yourself with is the Submit button which starts the whole process;
|
||
|
|
dialogs are presented as the process continues asking you if you want to
|
||
|
|
continue "OK" or stop "Cancel".</P>

The <u>first row</u> presently has only one Boot Method choice:
|
||
|
|
"2 disk compression."  
|
||
|
|
Clicking on the menu on the right selects the Boot Method.</p>
|
||
|
|
|
||
|
|
|
||
|
|
<P>The <u>second row</u> allows you to select the kernel for the Boot/Root set. You
|
||
|
|
may either use the file selector button on the right hand side, or you may
|
||
|
|
type in the location on the left hand side.</P>
|
||
|
|
|
||
|
|
<P>
|
||
|
|
The <u>third row</u> allows you to select the compressed filesystem you are
|
||
|
|
providing, using either of the two ways mentioned before. You may use a
|
||
|
|
pre-made root filesystem or you may create one using one of the Methods
|
||
|
|
provided in the Advanced Root Section.
|
||
|
|
</P>
|
||
|
|
|
||
|
|
|
||
|
|
<P>The <u>fourth row</u> allows you to select the device you want to use. The default
|
||
|
|
device is the first floppy disk - /dev/fd0.</P>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
The <u>fifth row</u> allows you to choose the size of the device being used.
|
||
|
|
The default size of 1440 assumes you are using a floppy drive (Note: You may
|
||
|
|
want to experiment with 1722 which works fine with many floppy drives.), but
|
||
|
|
can be used with other sized devices like tape drives. Click on the
|
||
|
|
appropriate radio button to choose either gzip or bzip2 compression if the
|
||
|
|
program doesn't automatically detect it.</p>

|
|
<IMG ALT="" SRC="images/verbosity_box.jpg" align="right">

The <u>slider bar</u> on the right allows the output of the verbosity box

to be

|
|
changed from the highest (2) to the lowest setting (1) or to be turned off (0)

or on again.
|
||
|
|
At times it may be advantageous to turn off the verbosity box
|
||
|
|
since large quantities of output to this box may cause gbootroot to use too
|
||
|
|
much cpu power; however, output may still be found in the text file "verbose"

This is the device used for the root filesystem when

constructing the Boot/Root set.
|

The check boxes at the bottom represent the different stages involved in
|
||
|
|
creating a root filesystem. The behavior of these stages may be altered in
|
||
|
|
three ways: Edit->Stages->one-by-one (default) will perform each stage
|
||
|
|
sequentially, stopping between each stage, the user may continue the process
|
||
|
|
by pressing the Continue button. Edit->Stages->continuous proceeds non-stop
|
||
|
|
through all the stages. Edit->Stages->'user defined' allows the user to
|
||
|
|
choose any stages the user wants, and will then proceed through all the
|
||
|
|
chosen stages. Choosing only 'Check', 'Links & Deps', 'Create" is a good
|
||
|
|
example.</p>

<P><IMG ALT="" SRC="images/gBSicon.jpg" align="center"> <b>FAQ</b></P>
|
||
|
|
<P><b>What does this program do?</b></P>
|
||
|
|
<P>gBootRoot creates a boot disk with lilo, a kernel and an initrd image. The
|
||
|
|
initrd script mounts another root disk with a compressed (gzip or bzip2)
|
||
|
|
filesystem.</P>
|
||
|
|
|
||
|
|
<P>The root filesystem isn't made by this program, but there lots of compressed
|
||
|
|
filesytems out there to use (see rest of FAQ). This program is patterned
|
||
|
|
after mkrboot, but unlike mkrboot it creates an unique bootdisk and a
|
||
|
|
separate root disk.</P>
|
||
|
|
|
||
|
|
<P><b>What's the advantage of using this program?</b></P>
|
||
|
|
|
||
|
|
<P>You can use a bzip2 compressed filesystem, this program is easy to use, and it provides a framework showing a simple initrd method which you can freely
|
||
|
|
modify. I wrote this program as an extension to BootRoot which was written
|
||
|
|
as a solution to help oster at EE (www.experts-exchange.com) create separate
|
||
|
|
boot and root floppies for an emergency system for his customers.</P>
|
||
|

<P><b>Why doesn't looplinux work as "bootdisk 1?"</b></P>
|
||
|
|
<P>There is a difference between "1" and "single." Looplinux was written in a
|
||
|
|
way that runlevel 1 doesn't work properly in relation to gBootRoot unless
|
||
|
|
single is used. And you thought they were the same thing? gBootRoot

|
proves otherwise. </P>

<P><b>gBootRoot doesn't start because it can't locate Gtk.pm?</b></P>

Move the device size to 1722. This is a trick that <a href="http://www.toms.net/rb/">tomsrtbt</a> uses on his famous rescue disk.</p>
|
||
|
|
|
||

|
<p><b>If you roll the floppy density counter down to 0 and then try go back

<p>

This is because of the way Gtk works. There are two adjustments,
|
||
|
|
step and page increments. When you press your first mouse button the step
|
||
|
|
has been set to 282 so that a person can easily switch between 1440 and 1722.
|
||
|
|
When you use your second mouse button the page is set at 360. You can go
|
||
|
|
down to zero by pressing your third mouse button on the down arrow. Now
|
||
|
|
page up with the second button to 1440 and step with the first button to
|
||
|
|
1722. Pretty cool, eh?</p>
