CONFIGURATION FILE PROCESSING

     When booting, the system first loads the boot manager for processing
sections and some commands like VIDEOMODE etc. The boot manager tries to
recognize all the sections in a configuration file and, if it finds
selectable sections, displays the list of these sections with a prompt to
select one of them for booting. This boot menu can contain up to ten
selectable sections to be user-selected. The sections COMMENT, PTSDOS,
COMMON, BOOTMGR and sections with names beginning with '$' can not be
selected from a boot manager prompt, but they can be enforced by FORCE
command. The boot menu doesn't appear, if there are none of the selectable
sections. Mode of operation of the Boot Manager can be defined with the
following commands in the BOOTMGR section:

AUTOCHECK = <ON>|<OFF> ;
     By default, AutoCheck = Off. When "ON", boot manager will use the
     user's input prerecorded into a file or CMOS memory, instead of a
     dialogue.

STORAGE = <FILE>|<CMOS> ;
     By default, Storage = FILE.  At the first call or on pressing <Esc>
     during booting, Boot manager will display a prompt for user selection.
     If a user presses '1','2',...,'0', the choise will be realized but not
     saved for further bootings.  If any of the above keys is pressed in
     combination with 'Alt', then the Boot Manager will ask the permission
     to process each line of the configuration file (See TRACE command).
     If the user inputs 'F1' - 'F10', the boot manager will save the number
     either in a file or in CMOS, depending on STORAGE.

FILENAME = [drive:][path]filename
     Specifies the filename for storing users input. By default,
     FILENAME = AUTOBOOT.SYS

CMOSADDR = <CMOS register address in decimal format>
     Specifies CMOS register for storing users input.  By default,
     CMOSADDR = 52

FORCE  = <section name>[,<section name>[, ... ]]
     Specifies a section or a list of sections, equivalent to those named
     "COMMON".

IGNORE = <section name>[,<section name>[, ... ]]
     Specifies a section or a list of sections which are to be ignored by
     the system.

COLOR  = <cc | < BLACK..WHITE [,BLACK..WHITE]>>
         [on]
         [ bb | BLACK..WHITE [,BLACK..WHITE] ]
     colors -
     BLACK,BLUE,GREEN,CYAN,RED,MAGENTA,BROWN,LIGHTGRAY
     DARKGRAY,LIGHTBLUE,LIGHTGREEN,LIGHTCYAN,LIGHTRED
     LIGHTMAGENTA,YELLOW,WHITE
     Where, cc - foreground color, bb - background color.
     Specifies boot manager prompt color.

DEFAULT = <section name>

TIMEOUT = <period in seconds>
     By default, TIMEOUT = 5 (sec). DEFAULT specifies a user selection 'by
     default'. TIMEOUT gives a time delay before the section is selected
     according to the DEFAULT command.

     Surely enough, the system will immediately make the right choice if the
     AUTOCHECK=YES and correct user information does exist. However, if such
     information does not exist or for any reasons (for instance, due to any
     modification in CPNFIG.xxx file) is unacceptable, then a standard
     prompt shall be given by the system, where the default selection will
     be marked with '+'. If no measures are taken after the TIMEOUT period
     or if you press [Enter], the system will load the marked section, but
     this choice will not be saved for further booting.

     By entering the global trace mode (processing each line of the
     configuration file after pressing Alt-1..9  in the BootMgr prompt) it
     is possible, by pressing  Alt-Y or Alt-N to answer all the prompts
     related to the global trace mode (no effect on the TRACE command
     itself).

     If in the [BOOTMGR] section it is specified:

         storage=FILE
         autocheck=YES

then the date of CONFIG.xxx creation will be stored together with
information on the selected section. So, after any modification of the file,
the system will consider the section selection information as incorrect and
will assume that it should be rewritten.
