Available BOOT commands:
? -or- help -- Display this message
boot [<filename>] -- Load and run specified program; default is BOOTPROG
dir [<dev>] -- List all files in /stand directory; default device is BOOTDEV
logo -- Display the logo image until a key is pressed
logo off -- Don't display logo
show [-a | <param>] -- Show boot parameter values
-a -- Show all boot parameters, even messages
<param> -- Show only the specified boot parameter
<param>=<value> -- Set the value of a boot parameter
<param>+=<value> -- Append the value to a boot parameter, inserting a comma
Parameters that are recognized by BOOT:
ALIGN=<num> -- Alignment requirement for FILES images
AUTOBOOT=yes|no|<num> -- Minimum time (sec) to wait while loading BOOTPROG
BLM=<filename>{,<filename>} -- Bootstrap Loadable Modules loaded into BOOT
BOOTDEV=<dev> -- Device BOOTPROG is loaded from
BOOTMSG1=<text> -- Message displayed when starting to boot
BOOTMSG2=<text> -- Message displayed when entering interactive mode
BOOTMSG3=<text> -- String displayed at beginning of command line
BOOTMSG4=<text> -- String displayed when waiting to display more
BOOTPROG=<filename> -- Filename of kernel or other program to load and run
CONSOLE=<dev> -- Device used by BOOT and BOOTPROG for console I/O
FILES=[<name>:]<filename>{,<filename>} -- Files to load and pass to BOOTPROG
PARAMS=<filename> -- Load another boot parameter file
MEMADJUST=[+|-]<range>{,(+|-)<range>} -- Memory overrides
TIMEOUT=<num> -- Execute "boot" command after <num> seconds if no input
READ-ONLY parameters that are generated by BOOT:
BOOTCONS=<num>,<num> -- Console I/O routines for BOOTPROG to use
BOOTSTAMP=<string> -- Media stamp from boot device (BOOTDEV)
BUSTYPES=<string>{,<string>} -- I/O bus type name(s)
KSYM=<num>,<num>,<num>,<num>,<num>,<num> -- BOOTPROG symbol table information
MEMORY=<range>[:<use>]{,<range>[:<use>]} -- Lists available and in-use memory
STARTDEV=<dev> -- Device the bootstrap itself is loaded from
USERPARAMS=<name>{,<name>} -- Names of user-modified parameters
Any <filename> may be preceded by a <dev> to override the default device.
Default device for BLM is STARTDEV; default for all others is BOOTDEV.
Standard devices for all <dev> except in the CONSOLE parameter are:
fd(<unit>)
- Floppy disk, drive #<unit> (only zero, for now)
hd(<unit>[,<partition>])
- Hard disk, drive #<unit> (from zero), partition #<partition>
- <partition> may also be specified as an OS type name, one of:
UNIX, XENIX, DOS (DOS_12 or DOS_16 or DOS_32 or DOS_EXT), NT, OS2
- if <partition> is omitted, default is "UNIX"
If a boot device is specified without a filename, the "boot" command will
perform a "raw boot" of the specified device. For example, use "b hd(0,dos)"
to boot DOS or Windows from the first hard drive.
For MEMADJUST and MEMORY, <range> is:
<low_address>-<high_address>
Addresses are in decimal, and may be specified in bytes, or suffixed with
"K" to indicate kilobytes (1024 bytes), "M" for megabytes, or "G" for
gigabytes. Addresses may not exceed 4G.
For MEMADJUST, each range preceded by a "+" is added to the known ranges
so far; each range preceded by a "-" is subtracted. Ranges are applied in
left-to-right order. If the first range has neither a "+" nor a "-", all
known ranges are discarded and replaced by this range. In general, memory
that is already in use is never discarded.
