resides on the CD in the CD-ROM drive. Each CDROM is
mounted and checked until the file that matches the path is
found.

custom installation or upgrade script, you must use uppercase
characters to provide the path of the script, for example,
ks=cdrom:/KS_CUST.CFG.
ks=file://path
Performs a scripted installation with the script at path.
ks=protocol://serverpath
Performs a scripted installation with a script located on the
network at the given URL. protocol can be http, https, ftp, or
nfs. An example using nfs protocol is
ks=nfs://host/porturl-path. The format of an NFS URL is
specified in RFC 2224.
ks=usb

About Installation and Upgrade Scripts
The installation/upgrade script is a text file, for example ks.cfg, that contains supported commands.
The command section of the script contains the ESXi installation options. This section is required and
must appear first in the script.
