Parameter
[Auto] Use this option to set the preference for Pre-Boot
IPv4 Network. If configured for Auto, all the network
IPv6 operations initiated in the pre boot environment occur
over IPv4 or IPv6. The order of the existing network
boot devices is not modified in the UEFI Boot Order list.
New network boot devices are added to the end of the
list using the default policy of the System BIOS. If
configured for IPv4, all the network operations initiated
in the pre boot environment only occur over IPv4. All
existing IPv6 network boot devices are removed in the
UEFI Boot Order. No new IPv6 network boot devices
are added to the list. If configured for IPv6, all the
network operations initiated in the pre boot environment
only occur over IPv6. All existing IPv4 network boot
devices in the UEFI Boot Order are removed. No new
IPv4 network boot devices are added to the list.
[Auto] Use this option to control the IPv6 DHCP Unique
DUID-LLT Identifier (DUID). If configured for Auto, the DUID is set
using the Universal Unique Identifier (UUID) of the
server, or using the DUID-LLT method if the server
UUID is not available. If configured for DUID-LLT, the
DUID is set based on the Link-layer Address Plus Time
[DUID-LLT] method.
[Enable] Use this option to configure the Network Boot Retry
Disabled Support. When enabled, the system BIOS attempts to
boot the network device up to the number of times
configured in the Network Boot Retry Count option
before attempting to boot the next network device. This
setting only takes effect when attempting to boot a
network device from the F12 function key and one-time
boot options.
0-X Use this option to control the number of times the
[20] system BIOS attempts to boot a network device.
