boot-
image=<all|optionrom|uefi|di
sabled>
Specifies which boot firmware images are served-up
to the BIOS during start-up. This parameter can not
be used if the
/Adapter

link-
speed=<auto|40g|10g|1g|100m>
Specifies the network link speed of the adapter used
by the Boot ROM the default is
auto.
On the
10GBASE-T adapters “auto” instructs the adapter to
negotiate the highest speed supported in common
with it’s link partner . On QSFP+, SFP+ adapters,
“auto” instructs the adapter to use the highest link
speed supported by the inserted SFP+ module. On
10GBASE-T and SFP+ adapters, any other value
specified will fix the link at that speed, regardless of
the capabilities of the link partner, which may result
in an inability to establish the link
