	Some commands may not be available.  Use the '?' command to list
	most available commands.

################################################################################

################################################################################
# Tautoboot DBoot after a delay

################################################################################
# Tboot DBoot immediately

	boot [<kernelname>] [-<arg> ...]

	Boot the system.  If arguments are specified, they are added to the
	arguments for the kernel.  If <kernelname> is specified, and a kernel
	has not already been loaded, it will be booted instead of the default
	kernel.

		echo Current device is $currdev

	will print the current device.

################################################################################
# Tframebuffer DManage framebuffer setup

	framebuffer on | off | get | list [depth] | set <display or mode number>

	Switch framebuffer mode on or off, get current mode, list available
	modes or set mode by using either display resolution or framebuffer
	mode number. If the system does not provide display resolution via

################################################################################
# Tls DList files

	ls [-l] [<path>]

	Displays a listing of files in the directory <path>, or the root

	remaining files will not be shown.

################################################################################
# Tpnpscan DScan for PnP devices

	pnpscan [-v]

	Scan for Plug-and-Play devices.  This command is normally automatically
	run as part of the boot process, in order to dynamically load modules
	required for system operation.

	process and escape to the loader prompt.

################################################################################
# Tset Sbootfile DSet the default boot file set

	set bootfile=<filename>[;<filename>...]

	Sets the default set of kernel boot filename(s). It may be overridden
	by setting the bootfile variable to a semicolon-separated list of
