NAME

     btxld -- link editor for BTX clients

SYNOPSIS

     btxld [-qv] [-b file] [-E address] [-e address] [-f format] [-l file] [-o filename] [-P page] [-W page] file

DESCRIPTION

     The btxld utility binds the specified client executable together with a BTX loader program and the BTX kernel, and creates a composite object
     file suitable for loading during the boot process.

     The options are:

     -q      Quiet: inhibit warnings.

     -v      Verbose: display information about the files processed.

     -b file
	     Specify the BTX kernel to be bound with the client.

     -E address
	     Set the client entry point.

     -e address
	     Set the BTX loader entry point.

     -f format
	     Specify the output format, where format is one of 'bin', 'aout', or 'elf'.

     -l file
	     Specify the BTX loader to be bound with the client.

     -o filename
	     Name the output file.  The default is ``a.out''.

     -P page
	     Specify the first page of the client's segment to be marked 'present', where page may be 0 or 1.

     -W page
	     Specify the first page of the client's segment to be marked 'writable', where page may be 0, and should not exceed the number of
	     pages occupied by the combined .text and .data segments of the client image.

EXIT STATUS

     The btxld utility exits 0 on success, and >0 if an error occurs.

BOOT.CONFIG(5)						      BSD File Formats Manual						    BOOT.CONFIG(5)

NAME

     boot.config -- Configuration file for the boot blocks

DESCRIPTION

     The boot.config file contains options for the FreeBSD boot block code.

     When the FreeBSD boot loader runs, it searches the ``a'' slice of the boot partition for a boot.config file (as a result, slices which are
     missing an ``a'' partition require user intervention during the boot process).  If the boot.config file is found, its contents are used as
     the default configuration options for the boot block code and are echoed to the system console.

     A valid format of this file is to put BIOS drive number, a controller type, a unit number, a partition, a kernel file name, and any other
     valid boot(8) option on a single line, as it is done at the ``boot:'' prompt.

     The options related to the boot image selection described below and all the other options available for boot.config are documented in detail
     in the boot(8) manual page.

FILES

     /boot.config  parameters for the boot blocks (optional)

EXAMPLES

     The command:

	   # echo "-P" > /boot.config

     will activate the serial console of FreeBSD.

     The command:

	   # echo "1:ad(1,a)/boot/loader" > /boot.config

     will instruct the second stage of boot(8) on the first disk to boot with the third boot(8) stage from the second disk.

     The command:

	   # echo "1:ad(1,a)/boot/loader -P" > /boot.config

     will do both of the above.
