For these situations, you need an + alternative way of booting that will always work (as long as the + hardware works). For typical PC's, this means booting from the + floppy drive.</P +><P +>Most Linux distributions allow one to create an + <I +CLASS="GLOSSTERM" +>emergency boot floppy</I +> during installation. + It is a good idea to do this. However, some such boot disks + contain only the kernel, and assume you will be using the programs + on the distribution's installation disks to fix whatever problem + you have. Sometimes those programs aren't enough; for example, + you might have to restore some files from backups made with + software not on the installation disks.</P +><P +>Thus, it might be necessary to create a custom root floppy + as well. The <I +CLASS="CITETITLE" +>Bootdisk HOWTO</I +> by Graham + Chapman (XXX citation) contains instructions for doing this. + You must, of course, remember to keep your emergency boot and + root floppies up to date.</P +><P +>You can't use the floppy drive you use to mount the root + floppy for anything else. This can be inconvenient if you only + have one floppy drive. However, if you have enough memory, you + can configure your boot floppy to load the root disk to a ramdisk + (the boot floppy's kernel needs to be specially configured for + this). Once the root floppy has been loaded into the ramdisk, + the floppy drive is free to mount other disks. </P +></DIV +><DIV +CLASS="NAVFOOTER" +><HR +ALIGN="LEFT" +WIDTH="100%"><TABLE +WIDTH="100%" +BORDER="0" +CELLPADDING="0" +CELLSPACING="0" +><TR +><TD +WIDTH="33%" +ALIGN="left" +VALIGN="top" +><A +HREF="x1693.html" +>Prev</A +></TD +><TD +WIDTH="34%" +ALIGN="center" +VALIGN="top" +><A +HREF="book1.html" +>Home</A +></TD +><TD +WIDTH="33%" +ALIGN="right" +VALIGN="top" +><A +HREF="c1705.html" +>Next</A +></TD +></TR +><TR +><TD +WIDTH="33%" +ALIGN="left" +VALIGN="top" +>Single user mode</TD +><TD +WIDTH="34%" +ALIGN="center" +VALIGN="top" +><A +HREF="c1582.html" +>Up</A +></TD +><TD +WIDTH="33%" +ALIGN="right" +VALIGN="top" +><B +CLASS="COMMAND" +>init</B +></TD +></TR +></TABLE +></DIV +></BODY +></HTML +>
