RedHat 9 (Linux i386) - man page for pcinitrd (redhat section 8)

PCINITRD(8)									      PCINITRD(8)

NAME
       pcinitrd - create a PCMCIA initrd ram disk image

SYNOPSIS
       pcinitrd  [-v] [-a] [--all] [-d alternate-root] [--dir=alternate-root] [-r kernel-release]
       [--release=kernel-release] [-s image-size]  [--size=image-size]	[-u]  [--update]  initrd-
       image [modules ...]

DESCRIPTION
       The  pcinitrd script creates an initrd ram disk image for booting with the root filesystem
       on a PCMCIA device.  If the target is a block special device (i.e.,  /dev/fd0),	then  the
       initrd  image is created on that device.  If the target does not already exist or if it is
       an ordinary file, then pcinitrd will create the image file using the ``loopback'' device.

       Modules are specified with paths relative to /lib/modules/[kernel-release].  The core PCM-
       CIA modules (pcmcia/pcmcia_core and pcmcia/ds) will automatically be installed in the tar-
       get image.  All other device-specific modules need to be listed on the command line, along
       with  the appropriate socket driver (pcmcia/i82365.o or pcmcia/tcic.o).	Alternatively, if
       -a is specified, then all available PCMCIA socket drivers and block device drivers will be
       included  in  the  image.   Additional  files to be copied to the initrd image may also be
       listed on the command line.   Executable  programs  will  be  installed	in  /bin,  shared
       libraries will be installed in /lib, device files will be installed in /dev, and any other
       files will be placed in /etc.

       The startup script in the resulting image, linuxrc, may need to be customized for  a  par-
       ticular	system.   It  contains the same variable definitions as the normal PCMCIA startup
       scripts (i.e., PCIC=, PCIC_OPTS=, and CORE_OPTS= variables).   The  /etc/config.opts  file
       may  also  need	to be edited.  Any changes to linuxrc or config.opts will be preserved if
       pcinitrd is executed in ``update'' mode.

       Another feature of the generated linuxrc is that if the DEBUG variable is set  to  a  non-
       blank  string  at  the  boot prompt, then cardmgr will echo all its status messages to the
       console, and after linuxrc executes, it will fire up a shell on the console.  This can  be
       helpful	for debugging initrd problems.	However, few commands are available in the normal
       initrd environment.

OPTIONS
       -v     Verbose mode.  Identify files as they are copied.

       -a, --all
	      Install all socket drivers and block-style PCMCIA device drivers, including  memory
	      card,  SCSI card, and fixed-disk drivers.  This is mainly intended for use by pack-
	      age maintainers.

       -d alternate-root, --dir=alternate-root
	      Specifies an alternate directory tree to search for  all	the  files  used  to  put
	      together	the initrd image.  This may be helpful for running pcinitrd after booting
	      from an installation or rescue diskette.

       -r kernel-release, --release=kernel-release
	      Specifies the kernel release number (i.e., 2.0.28) to use when looking for  modules
	      in /lib/modules.	The default is the release of the running kernel.

       -s image-size, --size=image-size
	      Specifies the filesystem size to create on the target file or device, in 1k blocks.
	      The default is 2400.

       -u, --update
	      Update mode: updates cardmgr and all the	kernel	modules  in  an  existing  initrd
	      image, but does not modify other files.
