# HELP USING THIS .CFG FILE
#   #    a single hash symbol comments out a line - these lines contain help or information - the # symbol should not be removed
#   ###  three hash symbols means you can uncomment and use these lines - they contain example grub4dos commands which can be used to change the E2B settings
#
#   e.g.
#       #  Auto menu      - this line should not be changed - do not delete the # symbol
#       ###set DEFM_MNU=0 - this line can be uncommented by deleting the ### symbols and then changed by the user if required

# If you wish, you can delete any whole line beginning with # or ### to make the file smaller and more legible

#       SUB-MENU HEADINGS are in the STRINGS.TXT language files (for different languages)
#       Menu entries and E2B phrases are also in each STRINGS.TXT file
#       DO NOT EDIT THE \_ISO\e2b\grub\ENG\STRINGS.TXT file - copy it to \_ISO\e2b\grub\FRED\STRINGS.TXT and use 'set LANG=FRED' in this file to use it

#  ------ USE ALTERNATE CFG FILE FOR 800x600 ----
# if you use 1024x768 (GMODE=1024), you can use the two lines below to use an alternate 800x600 MyE2B800.cfg config file if 1024x768 is not supported by the computer
###debug 1 ;; vbeprobe > (md)0x220+5 ;; debug 0
###cat --locate=1024x768x24 (md)0x220+5 > nul || /_ISO/MyE2B800.cfg && goto :EOF

#  ----- GRAPHICS MODE AND WALLPAPER -----
# set graphics mode - use 640 or 800 (recommended) or 1024 - or specify full mode - e.g. 800 600 24
# 800x600x24 is required for the default E2B background bitmap  - you can define exact size - e.g. GMODE=800 600  or  GMODE=800 -1 24:32 (800 by *anything* with 24 or 32-bit colour)
set GMODE=800

# set the WALLPAPER BACKGROUND
# The size of your background bmp must match the GMODE setting (e.g. use 1024x768 bitmap and set GMODE=1024)
# Change the path and filename below if you wish - .bmp and .bmp.gz supported (.bmp can be compressed using LZMA_Encode). grub4dos 0.4.6a also supports .jpg files.
set MYWBMP=/_ISO/mybackground.bmp

# If GMODE is set to a number (e.g. 800 or 1024 for graphics mode), then we can fill the screen with a single colour instead of using a bitmap
# This is quicker than loading a bitmap file - the colour value must begin with 0x (zero x) and must be in RGB format 0xrrggbb
###set MYWBMP=0xff0033

#    --------- MAIN MENU HEADING -----
# start the heading with \x20 if you need leading spaces.
# special variables can be used. %B64% is CPU type + Memory size - e.g. [486MB 64-bit];  %VER% is E2B version - e.g. 1.65. Use %@date% or %day%-%month%-%year% for date
# %@DATE%,%@TIME%,%day%,%month%,%year%,%VER%,%B64%,%SIZE_E2B%,%SIZE_HD1%,%^LANG%,%MEMSIZE%,%BITNESS%
# \xhh can be used for any ASCII character, \Xhhhh can be used for any Unicode character (e.g. \X00DC for Ü). \n can be used to start a new line. 

set HEADING=\x20 EASY2BOOT - MAIN MENU  (%VER%) %B64%

# Heading position is set by HEADPOS + HPAD - all menu headings are affected (must be 4 decimal numbers)
# set start position of HEADING using HEADPOS=YYXX  - default position = HEADPOS=0000 = top-left, 0200 = 3rd line down - should always end in 00 if you use CENTREHD=1
set HEADPOS=0000
# HPAD sets space padding (alignment) before all menu headings - NORMALLY, NO NEED TO CHANGE THIS!
# this is usually automatically calculated by E2B from the rstart value (\x20 is same as one space character)
###set HPAD=\x20              \x20

# ----- CENTRE ALL MENU HEADINGS -----
# CENTREHD=xx causes the menu headings to be centred inside xx characters - e.g. if CENTREHD=60 then middle will be at (HPAD)+30
# If CENTREHD=1 then the menuw value (see below) is used to calculate the centre position - Use CENTREHD=1 for normal auto-centred headings
# To centre all headings across an 800 pixel display (i.e. not centred on menu width) use  CENTREHD=98, HEADPOS=0000, HPAD=\x20
### set CENTREHD=1

# ----- HEADING COLOUR -------
# HCOLOUR sets the colour of the HEADING text 
# HCOLOUR=ABCD specifies the text colour  [BLINK|BRIGHT_F|BACKGROUND|FOREGROUND]
# A=0-1  1=BLINK text (does not work under VM or in graphics mode) - i.e. only works if GFX=none is used.
# B=0-1  1=BRIGHT_F sets bright value for foreground text
# C=0-7   =BACKGROUND colour - transparent if graphics mode so has no effect!
# D=0-7   =FOREGROUND menu text colour
# Colours parameters are: 0=black/grey 1=blue, 2=green, 3=cyan, 4=red, 5=pink, 6=yellow/brown, 7=grey/white.
# You can instead specify a hex RRGGBB colour for FCOLOUR and HCOLOUR - e.g. set HCOLOUR=0x00FFFF (does not work if in text mode GFX=none)
# e.g. 0133 is non-blinking bright cyan text (on a dark cyan background if not in graphics mode) - if a wallpaper is used (graphics mode) it becomes _1_3 = bright-cyan, because background value is ignored.
set HCOLOUR=0103

# --- FOOTER HELP TEXT TO DISPLAY AT BOTTOM OF SCREEN ---
# HBTM = Bottom HELPTEXT POSITION YYXX - for 640x480 use HBTM=2802 - for 800x600 use HBTM=3502  (Note: HPAD is NOT used to pad out the HELPTEXT). For GFX=none use HBTM=2400 or set >24 for off-screen.
set HBTM=3502

# Colour of HELPTEXT (see HCOLOUR above for meaning)
set FCOLOUR=0103

# use \x20 for no text at the bottom of the menus - e.g. set HELPTEXT=\x20   (%^LANG% will display the current language); use %@date% or %day%-%month%-%year% for date
set HELPTEXT=HDD0 [F7]   Back [F8]   Reboot [F9]   Power Off [F10]  (%^LANG%)


# -------- MENU COLOURS -------
# Colour pairs are Text/Background - i.e cyan/blue = cyan text on blue background (background colour used only if 8-bit colours used)
# Must use black if a transparent background is required for menu highlight background - e.g. highlight=red/black
# Valid 8-bit colours are: black, blue, green, cyan, red, magenta, brown, light-gray, dark-gray, light-blue, light-green, light-cyan, light-red, light-magenta, yellow and white.
#  normal    = normal menu text
#  highlight = highlighted menu text when a menu entry is selected
#  helptext  = the colour of the title help text shown just below the menu box
#  standard  = the console background and text colours (e.g. when listing files)
#  border    = the colour of the border of the menu box
#
# For GFX Boot menu, only color standard=xxxx/yyyy is valid (suggest use black background - e.g. color standard=cyan/black)
#
# -------- 8-BIT MENU COLOURS -------
color normal=light-cyan/black highlight=red/black helptext=yellow/black standard=light-cyan/black border=light-gray/black
#
# -------- 24-BIT MENU COLOURS -------
# You can instead set a 24-bit full colour value using 0xRRGGBB, the value must be larger than 0xFF to work correctly however
# in graphics mode (e.g. 800x600) only highlight colour can have a background colour - all others have transparent background colour
# the background colour will be set to black (transparent in graphics mode menus) if value is in range of 0x100 to 0xFFFFFF (not case sensitive)
#          0xRRGGBB         0xRRGGBB        0xRRGGBB  - See http://www.rapidtables.com/web/color/RGB_Color.htm
# e.g. Red=0xFF0000   Green=0x00FF00   Blue=0x0001FF  (value must be larger than FF so use 01FF!), Yellow=0xFFFF00, White=0xffffff, Brown=0x994c00
#
# Examples:
### color helptext=0xFFFFFF
### color standard=0x994c00
### color border=0xFF0000
### color normal=0x777700
### color highlight=0xFFFF00 ;; # yellow + background will be transparent
# highlight colour can also have a background colour
### color highlight=0x0022222200FFFF00  ;; # yellow + background will be 222222 (v. dark grey/black)
# If using pure blue color (0xff or less) use  color --64bit, (grub4dos 2019-06 or later) e.g.
### color --64bit normal=0x0000FF

# ----- MENU POSITION ---
# n = unchanged  (if wdspace or lnspace is not n then screen is cleared) - default for wdspace and lnspace is 0 or n
# if using GFX=none for text mode and CENTREHD=1, set menuw=78 and rstart=2 to get centred menu headings, max lines = 25, so change nomitems and topstart
# Note: The grub4dos menu system allows 4 lines of menu help text + 1 line for it's own messages (e.g. default timeout)
# Therefore you need to leave space for 5 free lines of text under the menu (e.g. if tophelp=26, then lines 26,27,28,29 & 30 are used for help text)
# 800x600 = 100 characters (0-99) by 37 lines (0-36),  1024x768 = 128 characters (0-127) by 48 lines (0-47)
# You can increase line separation using (for example) lnspace=8. Note that you will need to reduce topstart and noitems too
# rstart should be 2 or greater, do not use 0 or 1 or you may see offset text
# space between characters (best to leave this alone!)
###set wdspace=n
# space between lines (best to leave this alone of maybe use 2) - this affects number of lines per screen
###set lnspace=n

# ---- MENU NUMBERING ----
# E.g. The user can type '23' to select item 23 in the menu and so it is useful to have the menu item numbers displayed on the menu.
# Auto-numbering is enabled by default (AUTONUM=0x2001).  AUTONUM=CCMM where CC is the marker/arrow character (byte) and MM is 00 (off), 01 (number bootable entries) or 02 (number all entries) 
# Use AUTONUM=0x2000 to turn auto-numbering off, 0x2001 sets numbering on with a space after number (default), 0x2d01 autonumber with hyphen after number, 0x1a01 arrow, 0x3a01 colon, 0x0701 dot
