-SB100 device driver
-===================
-
-sb1000 is a module network device driver for the General Instrument (also known
-as NextLevel) SURFboard1000 internal cable modem board.  This is an ISA card
-which is used by a number of cable TV companies to provide cable modem access.
-It's a one-way downstream-only cable modem, meaning that your upstream net link
-is provided by your regular phone modem.
-
-This driver was written by Franco Venturi <fventuri@mediaone.net>.  He deserves
-a great deal of thanks for this wonderful piece of code!
-
-Needed tools
-============
-
-Support for this device is now a part of the standard Linux kernel.  The
-driver source code file is drivers/net/sb1000.c.  In addition to this
-you will need:
-
-1. The "cmconfig" program.  This is a utility which supplements "ifconfig"
-   to configure the cable modem and network interface (usually called "cm0");
-
-2. Several PPP scripts which live in /etc/ppp to make connecting via your
-   cable modem easy.
-
-   These utilities can be obtained from:
-
-      http://www.jacksonville.net/~fventuri/
-
-   in Franco's original source code distribution .tar.gz file.  Support for
-   the sb1000 driver can be found at:
-
-      - http://web.archive.org/web/%2E/http://home.adelphia.net/~siglercm/sb1000.html
-      - http://web.archive.org/web/%2E/http://linuxpower.cx/~cable/
-
-   along with these utilities.
-
-3. The standard isapnp tools.  These are necessary to configure your SB1000
-   card at boot time (or afterwards by hand) since it's a PnP card.
-
-   If you don't have these installed as a standard part of your Linux
-   distribution, you can find them at:
-
-      http://www.roestock.demon.co.uk/isapnptools/
-
-   or check your Linux distribution binary CD or their web site.  For help with
-   isapnp, pnpdump, or /etc/isapnp.conf, go to:
-
-      http://www.roestock.demon.co.uk/isapnptools/isapnpfaq.html
-
-Using the driver
-================
-
-To make the SB1000 card work, follow these steps:
-
-1. Run ``make config``, or ``make menuconfig``, or ``make xconfig``, whichever
-   you prefer, in the top kernel tree directory to set up your kernel
-   configuration.  Make sure to say "Y" to "Prompt for development drivers"
-   and to say "M" to the sb1000 driver.  Also say "Y" or "M" to all the standard
-   networking questions to get TCP/IP and PPP networking support.
-
-2. **BEFORE** you build the kernel, edit drivers/net/sb1000.c.  Make sure
-   to redefine the value of READ_DATA_PORT to match the I/O address used
-   by isapnp to access your PnP cards.  This is the value of READPORT in
-   /etc/isapnp.conf or given by the output of pnpdump.
-
-3. Build and install the kernel and modules as usual.
-
-4. Boot your new kernel following the usual procedures.
-
-5. Set up to configure the new SB1000 PnP card by capturing the output
-   of "pnpdump" to a file and editing this file to set the correct I/O ports,
-   IRQ, and DMA settings for all your PnP cards.  Make sure none of the settings
-   conflict with one another.  Then test this configuration by running the
-   "isapnp" command with your new config file as the input.  Check for
-   errors and fix as necessary.  (As an aside, I use I/O ports 0x110 and
-   0x310 and IRQ 11 for my SB1000 card and these work well for me.  YMMV.)
-   Then save the finished config file as /etc/isapnp.conf for proper
-   configuration on subsequent reboots.
-
-6. Download the original file sb1000-1.1.2.tar.gz from Franco's site or one of
-   the others referenced above.  As root, unpack it into a temporary directory
-   and do a ``make cmconfig`` and then ``install -c cmconfig /usr/local/sbin``.
-   Don't do ``make install`` because it expects to find all the utilities built
-   and ready for installation, not just cmconfig.
-
-7. As root, copy all the files under the ppp/ subdirectory in Franco's
-   tar file into /etc/ppp, being careful not to overwrite any files that are
-   already in there.  Then modify ppp@gi-on to set the correct login name,
-   phone number, and frequency for the cable modem.  Also edit pap-secrets
-   to specify your login name and password and any site-specific information
-   you need.
-
-8. Be sure to modify /etc/ppp/firewall to use ipchains instead of
-   the older ipfwadm commands from the 2.0.x kernels.  There's a neat utility to
-   convert ipfwadm commands to ipchains commands:
-
-	http://users.dhp.com/~whisper/ipfwadm2ipchains/
-
-   You may also wish to modify the firewall script to implement a different
-   firewalling scheme.
-
-9. Start the PPP connection via the script /etc/ppp/ppp@gi-on.  You must be
-   root to do this.  It's better to use a utility like sudo to execute
-   frequently used commands like this with root permissions if possible.  If you
-   connect successfully the cable modem interface will come up and you'll see a
-   driver message like this at the console::
-
-	 cm0: sb1000 at (0x110,0x310), csn 1, S/N 0x2a0d16d8, IRQ 11.
-	 sb1000.c:v1.1.2 6/01/98 (fventuri@mediaone.net)
-
-   The "ifconfig" command should show two new interfaces, ppp0 and cm0.
-
-   The command "cmconfig cm0" will give you information about the cable modem
-   interface.
-
-10. Try pinging a site via ``ping -c 5 www.yahoo.com``, for example.  You should
-    see packets received.
-
-11. If you can't get site names (like www.yahoo.com) to resolve into
-    IP addresses (like 204.71.200.67), be sure your /etc/resolv.conf file
-    has no syntax errors and has the right nameserver IP addresses in it.
-    If this doesn't help, try something like ``ping -c 5 204.71.200.67`` to
-    see if the networking is running but the DNS resolution is where the
-    problem lies.
-
-12. If you still have problems, go to the support web sites mentioned above
-    and read the information and documentation there.
-
-Common problems
-===============
-
-1. Packets go out on the ppp0 interface but don't come back on the cm0
-   interface.  It looks like I'm connected but I can't even ping any
-   numerical IP addresses.  (This happens predominantly on Debian systems due
-   to a default boot-time configuration script.)
-
-Solution
-   As root ``echo 0 > /proc/sys/net/ipv4/conf/cm0/rp_filter`` so it
-   can share the same IP address as the ppp0 interface.  Note that this
-   command should probably be added to the /etc/ppp/cablemodem script
-   *right*between* the "/sbin/ifconfig" and "/sbin/cmconfig" commands.
-   You may need to do this to /proc/sys/net/ipv4/conf/ppp0/rp_filter as well.
-   If you do this to /proc/sys/net/ipv4/conf/default/rp_filter on each reboot
-   (in rc.local or some such) then any interfaces can share the same IP
-   addresses.
-
-2. I get "unresolved symbol" error messages on executing ``insmod sb1000.o``.
-
-Solution
-   You probably have a non-matching kernel source tree and
-   /usr/include/linux and /usr/include/asm header files.  Make sure you
-   install the correct versions of the header files in these two directories.
-   Then rebuild and reinstall the kernel.
-
-3. When isapnp runs it reports an error, and my SB1000 card isn't working.
-
-Solution
-   There's a problem with later versions of isapnp using the "(CHECK)"
-   option in the lines that allocate the two I/O addresses for the SB1000 card.
-   This first popped up on RH 6.0.  Delete "(CHECK)" for the SB1000 I/O addresses.
-   Make sure they don't conflict with any other pieces of hardware first!  Then
-   rerun isapnp and go from there.
-
-4. I can't execute the /etc/ppp/ppp@gi-on file.
-
-Solution
-   As root do ``chmod ug+x /etc/ppp/ppp@gi-on``.
-
-5. The firewall script isn't working (with 2.2.x and higher kernels).
-
-Solution
-   Use the ipfwadm2ipchains script referenced above to convert the
-   /etc/ppp/firewall script from the deprecated ipfwadm commands to ipchains.
-
-6. I'm getting *tons* of firewall deny messages in the /var/kern.log,
-   /var/messages, and/or /var/syslog files, and they're filling up my /var
-   partition!!!
-
-Solution
-   First, tell your ISP that you're receiving DoS (Denial of Service)
-   and/or portscanning (UDP connection attempts) attacks!  Look over the deny
-   messages to figure out what the attack is and where it's coming from.  Next,
-   edit /etc/ppp/cablemodem and make sure the ",nobroadcast" option is turned on
-   to the "cmconfig" command (uncomment that line).  If you're not receiving these
-   denied packets on your broadcast interface (IP address xxx.yyy.zzz.255
-   typically), then someone is attacking your machine in particular.  Be careful
-   out there....
-
-7. Everything seems to work fine but my computer locks up after a while
-   (and typically during a lengthy download through the cable modem)!
-
-Solution
-   You may need to add a short delay in the driver to 'slow down' the
-   SURFboard because your PC might not be able to keep up with the transfer rate
-   of the SB1000. To do this, it's probably best to download Franco's
-   sb1000-1.1.2.tar.gz archive and build and install sb1000.o manually.  You'll
-   want to edit the 'Makefile' and look for the 'SB1000_DELAY'
-   define.  Uncomment those 'CFLAGS' lines (and comment out the default ones)
-   and try setting the delay to something like 60 microseconds with:
-   '-DSB1000_DELAY=60'.  Then do ``make`` and as root ``make install`` and try
-   it out.  If it still doesn't work or you like playing with the driver, you may
-   try other numbers.  Remember though that the higher the delay, the slower the
-   driver (which slows down the rest of the PC too when it is actively
-   used). Thanks to Ed Daiga for this tip!
-
-Credits
-=======
-
-This README came from Franco Venturi's original README file which is
-still supplied with his driver .tar.gz archive.  I and all other sb1000 users
-owe Franco a tremendous "Thank you!"  Additional thanks goes to Carl Patten
-and Ralph Bonnell who are now managing the Linux SB1000 web site, and to
-the SB1000 users who reported and helped debug the common problems listed
-above.
