*** 34,51 ****
  To run the examples:
  
! 1. Load the RT Linux functions:
  
! ./install_realtime_base
  
! 2. Load the real-time API functions:
  
! (NOTE: This has been added to the install_realtime_base script,
! so you can skip it and go straight to step 3)
  
! /sbin/insmod rtlib/rtl_rtapi.o
! or
! /sbin/insmod rtlib/rtai_rtapi.o
  
! depending upon which version of RT Linux you have.
  
  3. Run the timer task example:
--- 34,57 ----
  To run the examples:
  
! 1. Open a shell window, and begin watching the kernel log:
  
! tail -f /var/log/messages
  
! leave this running, and go back to your original shell window
  
! 2. Load the RT Linux functions:
! Note: for this and most of the following steps you will need
! to be root.
  
! ./install_realtime_base
  
! See a number of messages pop up in the kernel log as components
! of the RTOS are installed...
! One of the last ones will be:
! 
! <date> <time> <host> kernel: RTAPI: Initing
! 
! This means that thertapi module (either rtl_rtapi.o or
! rtai_rtapi.o) is loaded.
  
  3. Run the timer task example:
***************
*** 53,68 ****
  /sbin/insmod rtlib/timertask.o
  
  Wait a few seconds, then remove the module:
  
  /sbin/rmmod timertask
  
! Look at the output in the kernel log:
  
! tail /var/log/messages
  
! Jun 18 10:50:14 rebozo kernel: timertask: started timer task 
! Jun 18 10:50:18 rebozo kernel: timer task: timer count is 3251 
  
! You'll see that 3251 calls to the task were made. 
  
  4. Run the parallel port interrupt example:
--- 59,89 ----
  /sbin/insmod rtlib/timertask.o
  
+ A few messages will pop up in the kernel log as the task
+ is created and started:
+ 
+ <date> <time> <host> kernel: RTAPI: clock_set_period ( 1000000 )
+ <date> <time> <host> kernel: RTAPI: new_task c3ee3000, count = 1
+ <date> <time> <host> kernel: RTAPI: start_task c3ee3000
+ 
+ c3ee3000 is the task handle, and will vary.
+ You'll also see a message from the timertask module...
+ 
+ <date> <time> <host> kernel: timertask init: started timer task
+ 
  Wait a few seconds, then remove the module:
  
  /sbin/rmmod timertask
  
! A couple more messages from rtapi:
  
! <date> <time> <host> kernel: RTAPI: stop_task c3ee3000
! <date> <time> <host> kernel: RTAPI: delete_task c3ee3000, count = 0
  
! And one from timertask:
  
! <date> <time> <host> kernel: timertask exit: timer count is 8174
! 
! This means that 8174 calls to the task were made. (I let it
! run for about 8 seconds.)
  
  4. Run the parallel port interrupt example:
***************
*** 74,83 ****
  
  /sbin/rmmod extint
- tail /var/log/messages
  
! Jun 18 10:52:14 rebozo kernel: extint: interrupt count is 2522 
  
! 2,522 interrupts occurred, many for a single short of pin 10 due to
! contact noise.
  
  5. Run the shared memory example:
--- 95,106 ----
  
  /sbin/rmmod extint
  
! Again, you'll get messages from RTAPI, and one from the
! extint module:
  
! <date> <time> <host> kernel: extint: interrupt count is 2522
! 
! This means 2,522 interrupts occurred, many for a single short
! of pin 10 due to contact noise.
  
  5. Run the shared memory example:
***************
*** 88,91 ****
--- 111,175 ----
  
  See the shared memory heartbeat incrementing.
+ Use crtl-C to break out of shmemusr.
+ Then remove the realtime task
+ 
+ /sbin/rmmod shmemtask
+ 
+ 6. Run the semaphore example:
+ 
+ /sbin/insmod rtlib/master.o
+ 
+ The master task will start giving the semaphore once per
+ second, printing to the log when it does.
+ 
+ /sbin/insmod rtlib/slave.o
+ 
+ The slave attempts to get the semaphore, and prints each
+ time it succeeds.  Since the master has already given the
+ semaphore several times, and it is a counting semaphore,
+ the slave will run several times in a row.  Once it catches
+ up with the master, it will run right after the master runs.
+ Stop the tasks in reverse order:
+ 
+ /sbin/rmmod slave
+ /sbin/rmmod master
+ 
+ 7. Run the FIFO example:
+ 
+ /sbin/insmod rtlib/fifotask.o
+ 
+ The realtime fifotask will begin writing strings to the
+ fifo once per second, and echoing the strings to the log
+ file.
+ 
+ bin/fifousr
+ 
+ The user mode program will read strings from the fifo and
+ and print them out.
+ 
+ Use ctrl-c to exit fifousr, and stop the task:
+ 
+ /sbin/rmmod fifotask
+ 
+ 
+ 8. More elaborate tests:
+ 
+ In theory, you should be able to run any or all of the
+ above tests at the same time, doing insmod's and rmmod's
+ in any order. (Note - the semaphore master task must
+ always be installed before and removed after the slave
+ task.)
+ 
+ 9. Shutting down.
+ 
+ To remove the rtapi and the rest of the RTOS modules:
+ 
+ ./remove_realtime_base
+ 
+ If any tasks are still running, the script should print
+ the module names and refuse to procede.  Shut down the
+ modules (rmmod) and try again.
+ 
+

\layout Title

BDI Install Guide
\layout Section

Introduction
\layout Standard

First of all, the title is a misnomer.
 BDI stands for 
\emph on 
brain dead install
\emph default 
 so you shouldn't need a guide to its installation.
 However, there are times when you want a BDI install to coexist with your
 existing GNU/Linux or Microsoft installations.
 At such times it takes a little tweaking to boot BDI smoothly.
 This document explains the procedure.
\layout Standard

Firstly, backup everything critical.
 It is extremely improbable that there will be data loss due to something
 going wrong, but still, it is preferable to err on the side of caution.
 Data will be safe, but your PC may not boot.
 This is often enough to throw people into violent fits of panic.
 I mention it here to reassure you that in case something goes wrong (unlikely),
 your data is still there :-)
\layout Standard

People will boot into their OS of choice, normally through one of the following
 four methods: LILO, Loadlin, GRUB or a third party boot loader.
 I have no experience with the last two, so we'll concentrate on the rest.
 
\layout Standard

Throughout this document I'll be assuming that you have either Microsoft
 Windows 95/98 and/or GNU/Linux already installed.
\layout Section

The BDI install
\layout Standard

Make a separate partition to install BDI on.
 It does not matter if this partition is on a separate disk, primary or
 logical.
 (If you don't know what this means, you don't need to bother with it) A
 partition size of about 2.5 GB should be safe for almost all installs.
 Now install the BDI as you would install any regular GNU/Linux distribution,
 with the exception that if you already have some version of GNU/Linux,
 you should not install LILO.
\layout Standard

IMPORTANT:
\series bold 
 DO *NOT* INSTALL LILO IF YOU ALREADY HAVE GNU/LINUX INSTALLED!!!
\layout Standard

Not installing LILO can be achieved by un-checking a box on the same screen
 where it asks you if you want to install LILO on the MBR or on another
 partition.
\layout Standard

If you have only MS Windows installed, then you should install LILO into
 the MBR.
\layout Standard

Choose your packages, setup the video and complete the installation.
\layout Section

Booting the BDI
\layout Standard

A little theory here.
\layout Standard

At this point, you have installed BDI onto your hard disk, but you lack
 the ability to boot into it.
 When your PC boots, here is what actually happens.
 A small program called the boot loader looks around for a 
\emph on 
kernel
\emph default 
.
 The kernel is the core of the operating system.
 When you say 
\begin_inset Quotes eld
\end_inset 

linux
\begin_inset Quotes erd
\end_inset 

, you are (should be) referring to this kernel.
 Now, once the boot loader chooses a kernel, it loads this into memory and
 then all kinds of interesting things happen, until you find yourself staring
 at a login screen.
 When you installed the BDI, you got a kernel which is to be used along
 with it.
 However, you have not yet told your boot-loader where this kernel is and
 how it should be loaded.
\layout Standard

The technique for instructing the various boot-loaders will now be covered.
\layout Subsection

LILO
\layout Standard

LILO stands for LInux LOader.
 The name is deceptive.
 LILO can also boot other operating systems, like MS windows.
 If you have GNU/Linux installed, you might be using LILO to boot into it,
 or your windows installation.
 The configuration file '/etc/lilo.conf' decides how LILO behaves.
 The file will have a section like
\layout LyX-Code

image=/boot/vmlinuz 
\layout LyX-Code

label=linux 
\layout LyX-Code

read-only 
\layout LyX-Code

root=/dev/hda6
\layout Standard

The image= line tells LILO where the kernel is located.
 In this case, the kernel is the file 
\begin_inset Quotes eld
\end_inset 

vmlinuz
\begin_inset Quotes erd
\end_inset 

, in the /boot directory.
 (If you check out this file, you might find that it is a link to another
 file.
 That's quite alright).
 The label= field decides what text is displayed at the LILO prompt.
 
\begin_inset Quotes eld
\end_inset 

read-only
\begin_inset Quotes erd
\end_inset 

 means that the / partition should initially be loaded in read-only mode.
 We need not go into the reason for this, but it is essential.
 The root= line specifies the root (/) partition which the kernel should
 work with.
 There can be a number of sections like this, one for each kernel you have.
\layout Standard

Can you now guess how to make the BDI work with LILO? Its simple.
\layout Standard

You need to tell LILO where the BDI kernel is.
 So get a copy of the BDI kernel and copy it some place where LILO can find
 it.
 For example, copy it into the /boot directory of your current GNU/Linux
 installation.
 To do this, you'll have to access the partition where BDI is installed,
 grab its kernel from there, and copy it to /boot.
 Lets assume that BDI is installed on /dev/hda7.
 So
\layout LyX-Code

# mkdir /bdi
\layout LyX-Code

# mount /dev/hda7 /bdi
\layout LyX-Code

# cp -v /bdi/boot/vmlinuz-x.x.xxx-xxx /boot/bdi
\layout LyX-Code

# umount /bdi
\layout LyX-Code

# rmdir /bdi
\layout Standard

Here, vmlinuz-x.x.xxx-xxx is the file to which /bdi/boot/vmlinuz points to.
 For example, in BDI-2.18, it is vmlinuz-2.2.18-rtl3.0.
 The file /boot/bdi is your required kernel, and its root partition is /dev/hda7.
 Now add a section like the one below into your /etc/lilo.conf (back it up
 first)
\layout LyX-Code

image=/boot/bdi 
\layout LyX-Code

label=BDI
\layout LyX-Code

read-only 
\layout LyX-Code

root=/dev/hda7
\layout Standard

Now, you have to make LILO read the configuration file and understand the
 new settings.
 So run the command
\layout LyX-Code

# /sbin/lilo -v
\layout Standard

The next time you boot, you'll see a label 
\begin_inset Quotes eld
\end_inset 

BDI
\begin_inset Quotes erd
\end_inset 

.
 Hitting it will take you to the BDI.
\layout Subsection

Loadlin
\layout Standard

Loadlin is a DOS based program that is used to boot the linux kernel.
 If you are using Loadlin, you must be already proficient in its use.
 Simply copy the BDI kernel into your DOS dir, and use a command like 
\layout LyX-Code

loadlin bdi root=/dev/hda7
\layout Section

If something goes wrong
\layout Standard

Ok.
 Something happened and the system won't boot anymore.
 It happens to all of us.
 The important thing is not to panic.
 Go get a coffee or take a walk.
 Come back when you are calm once again :-)
\layout Standard

If you only had windows previously, then use its boot disk (you have one,
 don't you?) or boot from the Windows CD and at the command prompt type
 
\layout LyX-Code

c:> fdisk /mbr
\layout Standard

This will return things to their normal state.
\layout Standard

Or, you might have GNU/Linux previously installed, and now LILO fails to
 boot into any OS.
\layout Standard

In this case, boot into the first install CD (or the BDI CD) and go into
 rescue mode when you reach a prompt.
 Booting into rescue mode is pretty simple.
 Instructions are given on the screen.
 Most of the times, it is simply a matter of typing
\layout LyX-Code

linux rescue
\layout Standard

at the prompt.
\layout Standard

Once into rescue mode, you'll land up at a shell.
 Mount your original GNU/Linux / partition, chroot to it, replace the lilo.conf
 with your back up version and rerun LILO.
\layout LyX-Code

# mkdir /foo
\layout LyX-Code

# mount /dev/hda6 /foo
\layout LyX-Code

# chroot /foo
\layout LyX-Code

# mv -v /backup/of/lilo.conf /etc/lilo.conf
\layout LyX-Code

# /sbin/lilo -v
\layout LyX-Code

# <press ctrl+D>
\layout LyX-Code

# reboot
\layout Standard

This will restore LILO to its original state.
 Read this document once again, determine what went wrong, and try again.
