!BAT
:: GRUB4DOS batch script. See Tutorial at www.rmprepusb.com  Tutorial #96
:: Uses: Adds all *.iso file contents to make a single menu
::
:: %1 = .automenu
:: %2 = An optional \grub\xxx.HDR file can be included to contain default menu settings (color etc.)

:: This script used the default image file path as %2 variable - e.g. Vista == /%grub%/Vista.hdr

:: A menu file is generated in memory by this code for all ISO files in the /%2 folder and below
:: Run this grub4dos batch file using the following 2 lines

:: Example:
:: \grub\VistaMn.g4b .automenu Vista    - uses /%grub%/Vista.hdr (if exists) and looks in /_ISO/WINDOWS/Vista folder for ISOs
:: Configfile (md)0x3000+0x50
::
:: This script requires GRUB4DOS 2010-12-14 or later.

:: If ELBACKUP=YES then a copy of the generated menu will be written to
