<P>The package lodlin15.tgz available from sunsite.unc.edu
|

in <CODE>/pub/Linux/system/Bootutils</CODE>. This utility
|
|
is particularly suited to boot a <EM>Umsdos</EM> system. Generally

all you need to do is

<P>where zimage is a normal kernel image (compressed) simply copied

somewhere in the DOS drive. <CODE>D:</CODE> is the DOS drive where you

|

<P>
|
|
<P>Booting a <EM>Umsdos</EM> system from a floppy is not different from
|
|
booting a <EM>Ext2</EM> system. You need a kernel zImage file properly
|
|
initialize to locate your root <EM>Umsdos</EM> partition. This
|
|
is generally achieved using the command <CODE>rdev</CODE>. The following
|
|
sequence will initialize a zImage and put it on a floppy.

|
<P>

<P>
|
|
<P>LILO, the official <EM>Linux</EM> boot loader can also be used
|
|
to boot a <EM>Umsdos</EM> system. I have no experience with it
|
|
though. Since 1.1.60, it should work. Please email if you know
|
|
something.

<H2><A NAME="ss5.4">5.4 How to defragment a <EM>Umsdos</EM> partition</A>
|
|
</H2>
|
|
|
|
<P>
|
|
<P>It can be done using any popular DOS tool. There is nothing
|
|
particular about file produced by <EM>Umsdos</EM>. And <EM>Umsdos</EM>
|
|
do not expect anything particular (directory layout, directory
|
|
entry sequence, etc...) from the file system under it.
|
|
<P>As far as I know, there is no <EM>Linux</EM> tool to achieve this.
|
|
<P>
|
|
<H2><A NAME="ss5.5">5.5 Advance tricks</A>
|
|
</H2>
|
|
|
|
<P><EM>Umsdos</EM> rely on the <CODE>--linux-.---</CODE> which rely on the
|
|
<EM>DOS</EM> directory. Some users may want to experiment
|
|
a bit. The utility <CODE>udosctl</CODE> part of the umsdos_progs
|
|
package (containing <CODE>umssync</CODE> and <CODE>umssetup</CODE>) allows
|
|
basic directory operation (listing, deletion) independently
|
|
on the <CODE>--linux-.---</CODE> and the <EM>DOS</EM> directory.
