+To write an application to floppy disk, it must first be converted to

+Here <filename>app.elf</filename> is the final linked application
+executable, in ELF format (it may not have a <filename>.elf</filename>
+extension). The file <filename>app.bin</filename> is the resulting
+pure binary file. This must be written to the floppy disk with the

+<title>GRUB Bootloader Support</title>
+<para>
+If an application is built with the GRUB startup type, it is
+configured to be loaded by the GRUB bootloader.
+</para>
+<para>
+GRUB is an open source boot loader that supports many different
+operating systems. It is available from
+<ulink
+url="http://www.gnu.org/software/grub">http://www.gnu.org/software/grub</ulink>.
+The latest version of GRUB should be downloaded from there and installed.
+In Red Hat Linux version 7.2 and later it is the default bootloader
+for Linux and therefore is already installed.
+</para>
+<para>
+To install GRUB on a floppy disk from Linux you need to execute the
+following commands:
+</para>
+<screen>
+$ <userinput>mformat a:</userinput>
+$ <userinput>mount /mnt/floppy</userinput>
+$ <userinput>grub-install --root-directory=/mnt/floppy '(fd0)'</userinput>
+Probing devices to guess BIOS drives. This may take a long time.
+Installation finished. No error reported.
+This is the contents of the device map /mnt/floppy/boot/grub/device.map.
+Check if this is correct or not. If any of the lines is incorrect,
+fix it and re-run the script `grub-install'.

+$ <userinput>umount /mnt/floppy</userinput>
+</screen>
+<para>
+The file <filename>menu.lst</filename> is an example GRUB menu
+configuration file. It contains menu items to load some of the
+standard eCos tests from floppy or from partition zero of the first
+hard disk. You should, of course, customize this file to load your own
+application. Alternatively you can use the command-line interface of
+GRUB to input commands yourself.
+</para>
+<para>
+Applications can be installed, or updated simply by copying them to
+the floppy disk at the location expected by the
+<filename>menu.lst</filename> file. For booting from floppy disks it
+is recommended that the executable be stripped of all debug and symbol
+table information before copying. This reduces the size of the file
+and can make booting faster.
+</para>
+<para>
+To install GRUB on a hard disk, refer to the GRUB documentation. Be
+warned, however, that if you get this wrong it may compromise any
+existing bootloader that exists on the hard disk and may make any
+other operating systems unbootable. Practice on floppy disks or
+sacrificial hard disks first. On machines running Red Hat Linux
+version 7.2 and later, you can just add your own menu items to the
+<filename>/boot/grub/menu.lst</filename> file that already exists.

+<title>Debugging FLOPPY and GRUB Applications</title>
+<para>
+When RedBoot loads an application it also provides debugging services
+in the form of GDB remote protocol stubs. When an application is
+loaded stand-alone from a floppy disk, or by GRUB, these services are
+not present. To allow these application to be debugged, it is possible
+to include GDB stubs into the application.
+</para>
+<para>
+To do this, set the &quot;Support for GDB stubs&quot;
+(<literal>CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS</literal>) configuration
+option. Following this any application built will allow GDB to connect
+to the debug serial port (by default serial device 0, also known as
+COM1) whenever the application takes an exception, or if a Control-C
+is typed to the debug port. Ethernet debugging is not supported.
+</para>
+<para>
+The option &quot;Enable initial breakpoint&quot;
+(<literal>CYGDBG_HAL_DEBUG_GDB_INITIAL_BREAK</literal>) causes the HAL
+to take a breakpoint immediately before calling cyg_start(). This
+gives the developer a chance to set any breakpoints or inspect the
+system state before it proceeds. The configuration sets this option by
+default if GDB stubs are included, and this is not a RedBoot build. To
+make the application execute immediately either disable this option,
+or disable <literal>CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS</literal>.
