Express5800/R120h-1E, R120h-2E Maintenance Guide
Description
Use this option to let the Shell discover its startup
script URL using DHCP. This option is available
only if the 'HTTP Support' policy is not set to
'Disabled' and Auto-Start Script Location is set to
'Network Location', or 'Auto'. When set to 'Enabled',
the Shell sends DHCP requests with the DHCP
User Class option set to the string 'UEFIShell'. The
DHCP server must be configured to provide
HTTP/HTTPS or FTP URLs when this DHCP User
Class string is present in the DHCP request. The
User Class option is Option 77 when using DHCP
over IPv4, and Option 15 when using DHCP over
IPv6. URLs in HTTP/HTTPS must use either an
IPv4 or IPv6 server address, or a host name. FTP
formats are accepted using either an IPv4 server
address or a host name. The URL provided by the
DHCP server should match the 'HTTP Support'
policy. When 'HTTP Support' policy is set to 'Auto',
any HTTP/HTTPS or FTP URL provided by the
DHCP server is used. When policy is set to 'HTTPS
only', only HTTPS URLs are used, and other URLs
are ignored. When policy is set to 'HTTP only', only
HTTP or FTP URLs are used, and other URLs are
ignored. When policy is set to 'Disabled', the Shell
does not send any DHCP request.
Use this option to configure a network URL to a
UEFI Shell startup script. This option is available
and used only when the Auto-Start Script Location
is set to 'Network Location', or 'Auto', and the Shell
Auto-Start Script discovery using DHCP is set to
'Disabled'. URLs in HTTP/HTTPS are accepted
using either an IPv4 or IPv6 server address, or
using a host name. FTP formats are accepted
using either an IPv4 server address or a host
name. For example, the URLs can be in any of the
following formats: http://192.168.0.1/file/file.nsh,
http://example.com/file/file.nsh,
https://example.com/file/file.nsh,
http://[1234::1000]/file.nsh.
The file must end with an .nsh extension. When
configured, the Embedded UEFI Shell attempts to
load and execute the startup script from the
network location pointed to by this URL. When a
HTTPS URL is configured, you must enroll the
respective HTTPS server's TLS certificate under
Server Security > TLS(HTTPS) Options.
