5CV(10.1)							     5CV(10.1)

NAME
       5cv, mkppcimage, sqz - convert kernel executable to boot format

SYNOPSIS
       5cv [ -Dn ] [ -Hn ] [ -s ] executable outfile

       mkppcimage [ -l loadaddr ] executable outfile

       sqz [ -w ] [ -t ] executable

DESCRIPTION
       These   commands	  convert   a  kernel  executable  in  Inferno/Plan  9
       a.out(10.5) format into another format used by  a  third	 party's  boot
       loader.	 Most convert the input executable and write the new format to
       outfile.

       5cv converts an ARM executable into one of several alternative formats.
       The output format is controlled by the -H option:

       -H1     AIF for RISCOS.

       -H2     Plan 9.

       -H3     Boot for NetBSD.

       -H4     Headerless,  stripped, and padded to 2K in length. Used for the
	       ROM resident serial bootstrap loader in a Cirrus EP72xx.

       -H5     Headerless, and stripped, for general use.

       -H6     EPOC IMG format. Not a complete	conversion,  currently	suffi‐
	       cient  for  use	with some NT based downloaders which autosense
	       the file type by the "EP" signature, and then ignore  the  con‐
	       tents of the header.

       The other options are:

       -s     Strip symbol table.

       -Dn    Enables debug output.

       Mkppcimage  converts a PowerPC or ARM executable to a boot image format
       used by PPCBOOT and UBOOT.  The output file has a  PPCBOOT  image  with
       one  component labelled as an `OS kernel' for the appropriate architec‐
       ture, containing the a.out(10.6) header, text and initialised data, all
       uncompressed.   Symbols	are not included.  By default the load address
       is deduced from the executable's entry  point;  the  -l	option	allows
       loadaddr	 to be set explicitly, with the number in C syntax (decimal by
       default).  Other attributes are deduced from the executable.

       Sqz squeezes (compresses) the given ARM or PowerPC executable  using  a
       method  that  achieves  respectable  compression for executables but is
       much faster to decompress than (say) gzip's.  By default, both the pro‐
       gram text and initialised data are compressed; the -t option causes sqz
       to compress only the program text, leaving the data as-is.  By default,
       sqz  prints compression statistics on its standard error output; the -w
       option causes it also to write the compressed file on its standard out‐
       put.  Either the bootstrap that loads it must decompress the result, or
       a small uncompressed stub must also be  loaded  that  decompresses  the
       remainder.
