and edit the script to change settings that are unique for each host.

USB flash drive

CDROM

You can start an installation or upgrade script by typing boot command-line options at the boot command

line.

At boot time you might need to specify options to access the kickstart file. You can enter boot options by

pressing Shift+O in the boot loader. For a PXE boot installation, you can pass options through the

kernelopts line of the boot.cfg file. See “About the boot.cfg File,” on page 125 and “PXE Booting the ESXi

Installer,” on page 91.

A ks=... option must be given, to specify the location of the installation script. Otherwise, a scripted

installation or upgrade will not start. If ks=... is omitted, the text installer will proceed.

Supported boot options are listed in “Boot Options,” on page 116.

IMPORTANT After you upgrade or migrate your host to ESXi 5.0, you cannot roll back to your version 4.x

ESX or ESXi software. Back up your host before you perform an upgrade or migration, so that, if the

upgrade or migration fails, you can restore your 4.x host.
