The following per ‐ adapter parameters in Table 20 are used to control the
configurable parameters for the Boot ROM driver when running prior to the
operating system booting.
Table 20: Sfboot Per ‐ adapter Parameters
Parameter Description
link ‐ speed=auto|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 its link partner. On 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.

linkup ‐ delay=

<delay time in seconds>
Specifies the delay (in seconds) the adapter defers its first
connection attempt after booting, allowing time for the
network to come up following a power failure or other
restart. This can be used to wait for spanning tree protocol
on a connected switch to unblock the switch port after the
physical network link is established. The default is 5
seconds.
banner ‐ delay=

<delay time in seconds>
Specifies the wait period for
Ctrl ‐ B
to be pressed to enter
adapter configuration tool.
<delay time in seconds>
= 0 ‐ 256
bootskip ‐ delay=

<delay time in seconds>
Specifies the time allowed for
Esc
to be pressed to skip
adapter booting.
<delay time in seconds>
= 0 ‐ 256
boot ‐ type=pxe|disabled
Sets the adapter boot type – effective on next boot.
pxe
– PXE (Preboot eXecution Environment) booting
disabled
– Disable adapter booting
