<P>
You must create floppies from the bootdisk and rootdisk images that
you downloaded (or have on CD-ROM), no matter what type of installation
you will be doing.
<P>
On an MS-DOS system, you must uncompress the bootdisk and
rootdisk images using <tt>GZIP.EXE</tt>. For example, if you're
using the <tt>bare.gz</tt> bootdisk image, issue the MS-DOS command:
<P><TT> C:<code>\</code>&gt; GZIP -D BARE.GZ
<P></TT>
which will uncompress <tt>bare.gz</tt> and leave you with the file
<tt>bare</tt>. If you are installing from CD-ROM, you can copy
the bootdisk image (such as <tt>bare.gz</tt>) to you hard drive,
and run <tt>GZIP.EXE</tt> from the CD-ROM to uncompress it.
<P>
You must similarly uncompress the rootdisk image. For
example, if you are using the rootdisk <tt>color144.gz</tt>, issue the
command:
<P><TT> C:<code>\</code>&gt; GZIP -D COLOR144.GZ
<P></TT>
which will uncompress the file and leave you with <tt>color144</tt>.
<P>
Next, you must have two <em>high-density</em> MS-DOS formatted floppies.
(They must be of the same type; that is, if your boot floppy drive is
a 3.5&quot; drive, both floppies must be high-density 3.5&quot;
disks.) You will use <tt>RAWRITE.EXE</tt> to write the boot and rootdisk
images to the floppies.
<P>
Issue the command:
<P><TT> C:<code>\</code>&gt; RAWRITE
<P></TT>
<P>
Answer the prompts for the name of the file to write (such as <tt>bare</tt>,
or <tt>color144</tt>)
and the floppy to write it to (such as <tt>A:</tt>). <tt>RAWRITE</tt> will copy
the file, block-by-block, directly to the floppy. Also use <tt>RAWRITE</tt>
for the root disk image. When you're done, you'll
have two floppies: one containing the boot disk, the other containing
the root disk. Note that these two floppies will no longer be readable by
MS-DOS (they are ``Linux format'' floppies, in some sense).
<P>
Be sure that you're using brand-new, error-free floppies. The floppies
must have no bad blocks on them.
<P>
Note that you do not need to be running MS-DOS in order to install
Slackware. However, running MS-DOS makes it easier to create the boot and
root floppies, and it makes it easier to install the software (as you can
install directly from an MS-DOS partition on your system). If you are not
running MS-DOS on your system, you can use someone else's MS-DOS system just
to create the floppies, and install from there.
<P>
It is not necessary to use <tt>GZIP.EXE</tt> and <tt>RAWRITE.EXE</tt> under
MS-DOS to create the boot and root floppies, either. You can use the
<tt>gzip</tt> and <tt>dd</tt> commands on a UNIX system to do the same job.
(For this, you will need a UNIX workstation with a floppy drive,
of course.) For example, on a Sun workstation with the floppy drive on
device <tt>/dev/rfd0</tt>, you can use the commands:
<P><TT> <PRE>$ gunzip bare.gz
$ dd if=bare of=/dev/rfd0 obs=18k
</PRE>
<P></TT>
<P>
You must provide the appropriate block size argument (the <tt>obs</tt> argument)
on some workstations (e.g., Suns) or this will fail. If you have problems
the man page for <tt>dd</tt> will be instructive.
