Parameter Description
Boot from URL X
HTTP/HTTPS URL
Use this option to configure a network URL to a
bootable ISO or EFI file. URLs in HTTP/HTTPS are
accepted using either an IPv4 or IPv6 server
address, or using a host name. For example, the
URLs can be in any of the following formats:
http://192.168.0.1/file/image.iso,
http://example.com/file/image.efi,
https://example.com/file/image.efi,
http://[1234::1000]/image.iso.
When configured, this URL is listed as a boot
option in the UEFI boot menu. Selecting this boot
option downloads the file to the system memory,
and configures the system to attempt to boot from
it. There is no specific ordering on this option. It can
be independently ordered in the boot menu.
This setting requires configuring the 'Pre-Boot
Network Interface' option if you want to access the
URL location through a specific network interface.
When a HTTPS URL is configured, this setting
requires enrolling the respective TLS certificate of
the HTTPS server under Server Security > TLS
(HTTPS) Options.
This is only applicable in UEFI Mode.
Note: Booting from an ISO file can involve only
booting a preliminary OS environment image, such
as WinPE or a mini Linux, or a complete OS install
image if the OS supports the HTTP Boot feature
(Old OS versions may not support this). Please
check your OS documentation for the HTTP Boot
feature support.
