If any of the hardware in your system <strong>requires firmware to be
loaded</strong> with the device driver, you can use one of the
<a href="https://cdimage.debian.org/cdimage/unofficial/non-free/firmware/lenny/current/">\
tarballs of common firmware packages</a>. Instructions how to use the tarballs
and general information about loading firmware during an installation can
be found in the Installation Guide (see Documentation below).

#   <if-lennynhalf-released released="yes"><li>
#	Information about <strong>installing Debian GNU/Linux

    <li>
	For downloading full CD and DVD images the use of bittorrent or jigdo
	is recommended.
    </li><li>
	For the less common architectures only a limited number of images
	from the CD and DVD sets is available as ISO file or via bittorrent.
	The full sets are only available via jigdo.
    </li><li>
	The multi-arch <em>CD</em> images support i386/amd64/powerpc and
	alpha/hppa/ia64 respectively; the installation is similar to installing
	from a single architecture netinst image.
    </li><li>
	The multi-arch <em>DVD</em> image supports i386/amd64; the
	installation is similar to installing from a single architecture full
	CD image; the DVD also includes the source for all included packages.
    </li><li>
	For the installation images, verification files (<tt>SHA256SUMS</tt>,
	<tt>SHA512SUMS</tt> and other) are available from the same directory as the
	images.

<p>
This is a list of known problems in the installer shipped with 
Debian GNU/Linux <current_release_lenny>. If you have experienced a problem
installing Debian and do not see your problem listed here, please send us an 
<a href="$(HOME)/releases/stable/i386/ch05s04.html#submit-bug">installation report</a>
describing the problem or 
<a href="https://wiki.debian.org/DebianInstaller/BrokenThings">check the wiki</a>
for other known problems.
</p>

<h3 id="errata-r0">Errata for release 5.0</h3>

<dl class="gloss">
	<dt>Auto-assembly of RAID arrays in rescue mode can corrupt data</dt>
	<dd>
        Rescue mode should be used with great care when software RAID
        arrays were in use on the system to rescue. The rescue mode scripts
        automatically assemble arrays, which could lead to data corruption in
        the presence of invalid or obsolete RAID superblocks.
	</dd>

	<dt>Corrupted display of messages in Dzongkha installs</dt>
	<dd>
	When the password chosen for root and its confirmations do not
        match, the display of screens that follow is garbled, during
        installs in Dzongkha language (broken display of italic
        font).
	</dd>

	<dt>Disk devices may change on reboot</dt>
	<dd>
	On systems with multiple disk controllers, the kernel/udev may assign
	a different device node on reboot of the system than was used during
	installation due to difference in load order of drivers.<br />
	This can lead to failure to boot the system. In most cases this can be
	corrected by changing the bootloader configuration and /etc/fstab,
	possibly using the rescue mode of the installer.<br />
	Note however that this problem may occur again on subsequent boots.
	</dd>

	<dt>Reboot problems when installing from a USB stick</dt>
	<dd>
	The former problem may also happen when installing from a USB stick.
	Temporarily keeping the USB stick in place will allow you
	to boot the installed system and correct the bootloader
	configuration file. See 
	<a href="https://bugs.debian.org/506263">#506263</a>
	for details about such workaround.
	</dd>

	<dt>Buggy routers may cause network problems</dt>
	<dd>
	If you experience network problems during the installation, this may be
	caused by a router somewhere between you and the Debian mirror that
	doesn't correctly handle window scaling.
	See <a href="https://bugs.debian.org/401435">#401435</a> and this
	<a href="http://kerneltrap.org/node/6723">kerneltrap article</a> for
	details.<br />
	You can work around this issue by disabling TCP window scaling. Activate
	a shell and enter the following command:<br />
	<tt>echo 0 &gt; /proc/sys/net/ipv4/tcp_window_scaling</tt><br />
	For the installed system you should probably not completely disable TCP
	window scaling. The following command will set ranges for reading and
	writing that should work with almost any router:<br />
	<tt>echo 4096 65536 65536 &gt;/proc/sys/net/ipv4/tcp_rmem</tt><br />
	<tt>echo 4096 65536 65536 &gt;/proc/sys/net/ipv4/tcp_wmem</tt>
	</dd>

	<dt>Not usable for installing Squeeze or Sid</dt>
	<dd>
	Due to changes in the <tt>passwd</tt> package in testing and unstable,
	setting up a user account will fail. For details see
	<a href="https://bugs.debian.org/529475">#529475</a>.

	<dt>i386: more than 32 mb of memory is needed to install</dt>
	<dd>
	The minimum amount of memory needed to successfully install on i386
	is 48 mb, instead of the previous 32 mb. We hope to reduce the
	requirements back to 32 mb later. Memory requirements may have
	also changed for other architectures.
	</dd>
-->

	<dt>i386: various issues</dt>
	<dd>
	The i386 port has some known issues in this release:
	<ul>
	<li>Due to an increase in the size of the Linux kernel, we are unable
	to provide installation images for installs from floppy disk.</li>
	<li>We had at least one report about the installer crashing at
	  the network hardware detection step on some Dell Inspiron laptops.
	  See <a href="https://bugs.debian.org/509238">bug #509238</a>
	  for details. A workaround seems to be booting the installer with
	  the <q>vga=771</q> parameter.</li>
	  </ul>
	</dd>

	<dt>PowerPC: various issues</dt>
	<dd>
	The PowerPC port has several issues in this release:
	<ul>
		<li>installation from floppy on OldWorld PowerMac is broken
		    because no device node is created for the swim3 module
		    and as miboot is not included</li>
		<li>the snd-powermac module is no longer loaded by default as
		    it will lock up some systems; you will need to add it to
		    <tt>/etc/modules</tt> manually</li>
	</ul>
	</dd>

	<dt>s390: unsupported features</dt>
	<dd>
	<ul>
		<li>support for the DASD DIAG discipline is currently not
		    available</li>
		<li>support for LCS network interfaces is no longer available</li>
	</ul>
	</dd>
