The diskette<em>images</em> are located in the <tt>images</tt> directory on theRed Hat Linux CD or the FTP site where you got Red Hat Linux. Each image is a``snapshot'' of the appropriate floppy diskette, which you need totransfer onto an actual floppy; you can do this using either MS-DOS orLinux.<p><h4><a name="s2.3.1.1">2.3.1.1 Making Floppies Under MS-DOS</a></h4><title>Making Floppies Under MS-DOS</title><a name="i33"><p>To make floppies under MS-DOS, use the <tt>rawrite</tt> utility includedon the Red Hat Linux CD in the <tt>dosutils</tt> directory.

Then, use the following commands(assuming your CD is drive <tt>d:</tt>):<p><blockquote><pre>d:cd \images\dosutils\rawrite.exe</pre></blockquote><p><tt>rawrite</tt> first asks you for the filename of a diskette image;enter <tt>boot.img</tt>.

In fact,the installation system presents several different kinds of diagnosticmessages while running, and it gives you a means to enter commands froma shell prompt. It presents the installation dialogs, shell prompt,and messages on five <em>virtual consoles</em> which you can switchbetween using a single keystroke. These virtual consoles can be veryhelpful if you encounter a problem while installing Red Hat Linux; messagesdisplayed on the install log or system log can help to pinpoint theproblem. Please see Figure <a href="doc016.html#f1">1</a> for a listing of thevirtual consoles, the keystrokes to switch to them, and their contents.<p><p><a name="f1"></a><center><table border><tr valign=top><td colspan=1 align=center nowrap><b>Console</b> </td><td colspan=1 align=center nowrap> <b>Keystroke</b> </td><td colspan=1 align=left nowrap> <b>Contents</b></td></tr><tr valign=top><td colspan=1 align=center nowrap> 1 </td><td colspan=1 align=center nowrap> <tt>[Alt]</tt>-<tt>[F1]</tt> </td><td colspan=1 align=left nowrap> installation dialog</td></tr><tr valign=top><td colspan=1 align=center nowrap> 2 </td><td colspan=1 align=center nowrap> <tt>[Alt]</tt>-<tt>[F2]</tt> </td><td colspan=1 align=left nowrap> shell prompt</td></tr><tr valign=top><td colspan=1 align=center nowrap> 3 </td><td colspan=1 align=center nowrap> <tt>[Alt]</tt>-<tt>[F3]</tt> </td><td colspan=1 align=left nowrap> install log (messages from install program)</td></tr><tr valign=top><td colspan=1 align=center nowrap> 4 </td><td colspan=1 align=center nowrap> <tt>[Alt]</tt>-<tt>[F4]</tt> </td><td colspan=1 align=left nowrap> system log (messages from kernel, etc.)</td></tr><tr valign=top><td colspan=1 align=center nowrap> 5 </td><td colspan=1 align=center nowrap> <tt>[Alt]</tt>-<tt>[F5]</tt> </td><td colspan=1 align=left nowrap> other messages</td></tr></table><p><center>Figure 1:Virtual Console Information</center></center><p><p><h3><a name="s2.3.3">2.3.3 Using the Dialog Boxes</a></h3><title>Using the Dialog Boxes</title><p>You can navigate around the installation dialogs using a simple set ofkeystrokes.
