About the boot.cfg File
The boot loader configuration file boot.cfg specifies the kernel, the kernel options, and the boot modules
that the mboot.c32 or mboot.efi boot loader uses in an ESXi installation.
The boot.cfg file is provided in the ESXi installer. You can modify the kernelopt line of the boot.cfg
file to specify the location of an installation script or to pass other boot options.
The boot.cfg file has the following syntax:
# boot.cfg -- mboot configuration file
#
# Any line preceded with '#' is a comment.
title=STRING
prefix=DIRPATH
kernel=FILEPATH
kernelopt=STRING
modules=FILEPATH1 --- FILEPATH2... --- FILEPATHn
# Any other line must remain unchanged.
The commands in boot.cfg configure the boot loader.
