Merge from HEAD. This is part of a multi-part commit since the SGML tools
need to be merged as well for this to work, but they're in a different part of the subtree. I have to merge this because a) our -stable docs are way out of date and b) I need the "doc" distribution to appear in -stable if I'm to use a single copy of sysinstall for both. Reviewers of this MOST welcome!

+ <p>
+ The general idea is that one copies the first sector of your
+ native root Linux or FreeBSD partition into a file in the DOS/NT
+ partition. Assuming one names that file something like
+ <tt>c:&bsol;bootsect.lnx</tt> or <tt>c:&bsol;bootsect.bsd</tt>
+ (inspired by <tt>c:&bsol;bootsect.dos</tt>) one can then edit the

+ [operating systems]
+ multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows NT"

+ </verb>
+ This procedure assumes that DOS, NT, Linux, FreeBSD, or whatever
+ have been installed into their respective fdisk partitions on the
+ <bf/same/ disk. In my case DOS &amp; NT are in the first fdisk
+ partition, Linux in the second, and FreeBSD in the third. I also

+ In FreeBSD:

+ In a nutshell, there a few I/O ports that all of the PnP boards
+ respond to when the host asks if anyone is out there. So when
+ the PnP probe routine starts, he asks if there are any PnP boards
+ present, and all the PnP boards respond with their model &num; to
+ a I/O read of the same port, so the probe routine gets a wired-OR
+ ``yes'' to that question. At least one bit will be on in that
+ reply. Then the probe code is able to cause boards with board
+ model IDs (assigned by Microsoft/Intel) lower than X to go
+ ``off-line''. It then looks to see if any boards are still
+ responding to the query. If the answer was ``<tt/0/'', then
+ there are no boards with IDs above X. Now probe asks if there
+ are any boards below ``X''. If so, probe knows there are boards
+ with a model numbers below X. Probe then asks for boards greater
+ than X-(limit/4) to go off-line. If repeats the query. By
+ repeating this semi-binary search of IDs-in-range enough times,
+ the probing code will eventually identify all PnP boards present
+ in a given machine with a number of iterations that is much lower
+ than what 2^64 would take.
+ The IDs are two 32-bit fields (hence 2&circ;64) + 8 bit checksum.
+ The first 32 bits are a vendor identifier. They never come out
+ and say it, but it appears to be assumed that different types of
+ boards from the same vendor could have different 32-bit vendor
+ ids. The idea of needing 32 bits just for unique manufacturers
+ is a bit excessive.
+ The lower 32 bits are a serial &num;, ethernet address, something
+ that makes this one board unique. The vendor must never produce
+ a second board that has the same lower 32 bits unless the upper
+ 32 bits are also different. So you can have multiple boards of
+ the same type in the machine and the full 64 bits will still be
+ unique.
+ The 32 bit groups can never be all zero. This allows the
+ wired-OR to show non-zero bits during the initial binary search.
+ Once the system has identified all the board IDs present, it will
+ reactivate each board, one at a time (via the same I/O ports),
+ and find out what resources the given board needs, what interrupt
+ choices are available, etc. A scan is made over all the boards
+ to collect this information.
+ This info is then combined with info from any ECU files on the
+ hard disk or wired into the MLB BIOS. The ECU and BIOS PnP
+ support for hardware on the MLB is usually synthetic, and the
+ peripherals don't really do geniune PnP. However by examining
+ the BIOS info plus the ECU info, the probe routines can cause the
+ devices that are PnP to avoid those devices the probe code cannot
+ relocate.
+ Then the PnP devices are visited once more and given their I/O,
+ DMA, IRQ and Memory-map address assignments. The devices will
+ then appear at those locations and remain there until the next
+ reboot, although there is nothing that says you can't move them
+ around whenever you want.
+ There is a lot of oversimplification above, but you should get
+ the general idea.
+ Microsoft took over some of the primary printer status ports to
+ do PnP, on the logic that no boards decoded those addresses for
+ the opposing I/O cycles. I found a genuine IBM printer board
+ that did decode writes of the status port during the early PnP
+ proposal review period, but MS said ``tough''. So they do a
+ write to the printer status port for setting addresses, plus that
+ use that address + <tt/0x800/, and a third I/O port for reading
+ that can be located anywhere between <tt/0x200/ and <tt/0x3ff/.

+ <heading>I have 128 MB of RAM but it seems that the system use only the first 64 MB. What's going on ?</heading>
+ <p>
+ Due to the manner in which FreeBSD gets the memory size from the
+ BIOS, it can only detect 16 bits worth of Kbytes in size (65535
+ Kbytes = 64MB). If you have more than 64MB, FreeBSD will only see
+ the first 64MB. To work around this problem, you need to use the
+ kernel option specified below. There is a way to get complete
+ memory information from the BIOS, but we don't have room in the
+ bootblocks to do it. Someday when lack of room in the bootblocks
+ is fixed, we'll use the extended BIOS functions to get the full
+ memory information...but for now we're stuck with the kernel
+ option.

+ options "MAXMEM=<n>"

+ <heading>Sometimes my FreeBSD 2.0 reboots saying: ``Panic: kmem_map (or mb_map) too small !''.
+ <p>
+ The panic indicates that the system ran out of virtual memory for
+ network buffers (specifically, mbuf clusters). You can increase
+ the amount of VM available for mbuf clusters by adding:
+ <code>
+ options "NMBCLUSTERS=<n>"
+ </code>
+ to your kernel config file, where &lt;n&gt; is a number in the
+ range 512-4096, depending on the number of concurrent TCP
+ connections you need to support. I'd recommend trying 2048 - this
+ should get rid of the panic completely. You can monitor the

+ <heading>Now that I've got all through my UUCP setup, how do I convince sendmail to use it for mail delivery?</heading>
+ <p>
+ The sendmail configuration that ships with FreeBSD is
+ suited for sites that connect directly to the Internet.
+ Sites that wish to exchange their mail via UUCP must install
+ another sendmail configuration file.
+ <p>
+ Tweaking <tt>/etc/sendmail.cf</tt> manually is considered
+ something for purists. Sendmail version 8 comes with a
+ new approach of generating config files via some <tt>m4</tt>
+ preprocessing, where the actual hand-crafted configuration
+ is on a higher abstraction level. You should use the
+ configuration files under
+ /usr/src/usr.sbin/sendmail/cf
+ If you don't have installed your system with full sources,
+ this won't be a problem. The sendmail config stuff has been
+ broken out into a separate source distribution tarball just
+ for you. Assuming you've got your CD-ROM mounted, do:
+ cd /usr/src
+ tar -xvzf /cdrom/dists/src/ssmailcf.aa
+ Don't bother, this is only a few hundred kilobytes in size.
+ The file <tt>README</tt> in the <tt>cf</tt> directory can
+ serve as a basic introduction into the m4 configuration.
+ <p>
+ For UUCP delivery, you will go best by using the
+ <em>mailertable</em> feature. This constitutes a database
+ that sendmail can use to base its routing decision upon.
+ <p>
+ First, you have to create your <tt>.mc</tt> file. The
+ directory <tt>/usr/src/usr.sbin/sendmail/cf/cf</tt> is the
+ home of these files. Look around, there are already a few
+ examples. Assuming you have named your file <tt>foo.mc</tt>,
+ all you need to do in order to convert it into a valid
+ <tt>sendmail.cf</tt> is:
+ cd /usr/src/usr.sbin/sendmail/cf/cf
+ make foo.cf
+ cp foo.cf /etc/sendmail.cf
+ A typical <tt>.mc</tt> file might look like:
+ include(`../m4/cf.m4')
+ VERSIONID(`Your version number')
+ OSTYPE(bsd4.4)
+ FEATURE(nodns)
+ FEATURE(nocanonify)
+ FEATURE(mailertable)
+ define(`UUCP_RELAY', your.uucp.relay)
+ define(`UUCP_MAX_SIZE', 200000)
+ MAILER(local)
+ MAILER(smtp)
+ MAILER(uucp)
+ Cw your.alias.host.name
+ Cw youruucpnodename.UUCP
+ The <em>nodns</em> and <em>nocanonify</em> features will
+ prevent any usage of the DNS during mail delivery. The
+ <em>UUCP_RELAY</em> clause is needed for bizarre reasons,
+ don't ask. Simply put an Internet hostname there that
+ is able to handle .UUCP pseudo-domain addresses; most likely,
+ you will enter the mail relay of your ISP there.
+ <p>
+ Once you've got this, you need this file called
+ <tt>/etc/mailertable</tt>. A typical example of this
+ gender again:
+ #
+ # makemap hash /etc/mailertable.db < /etc/mailertable
+ #
+ horus.interface-business.de uucp-dom:horus
+ .interface-business.de uucp-dom:if-bus
+ interface-business.de uucp-dom:if-bus
+ .heep.sax.de smtp8:%1
+ horus.UUCP uucp-dom:horus
+ if-bus.UUCP uucp-dom:if-bus
+ . uucp-dom:sax
+ As you can see, this is part of a real-life file. The first
+ three lines handle special cases where domain-addressed mail
+ should not be sent out to the default route, but instead to
+ some UUCP neighbour in order to ``shortcut'' the delivery
+ path. The next line handles mail to the local Ethernet
+ domain that can be delivered using SMTP. Finally, the UUCP
+ neighbours are mentioned in the .UUCP pseudo-domain notation,
+ to allow for a ``uucp-neighbour!recipient'' override of the
+ default rules. The last line is always a single dot, matching
+ everything else, with UUCP delivery to a UUCP neighbour that
+ serves as your universal mail gateway to the world. All of
+ the node names behind the <tt>uucp-dom:</tt> keyword must
+ be valid UUCP neighbours, as you could verify using the
+ command <tt>uuname</tt>.
+ <p>
+ As a reminder that this file needs to be converted into a
+ DBM database file before being usable, the command line to
+ accomplish this is best placed as a comment at the top of
+ the mailertable. You always have to execute this command
+ each time you change your mailertable.
+ <p>
+ Final hint: if you are uncertain whether some particular
+ mail routing would work, remember the <tt>-bt</tt> option to
+ sendmail. It starts sendmail in <em>address test mode</em>,
+ simply enter ``0 '', followed by the address you wish to
+ test for the mail routing. The last line tells you the used
+ internal mail agent, the destination host this agent will be
+ called with, and the (possibly translated) address. Leave
+ this mode by typing Control-D.
+ j@uriah 191% sendmail -bt
+ ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
+ Enter <ruleset> <address>
