Drv[45] Ctrl[1C] Lang[eng]
Drv[45] Ctrl[1D] Lang[eng]
This listing shows which driver controls which device (controller). This information describes
a SCSI interface because the values shown for
Ctrl
—
17
and
18
are the controller handles
for the SCSI interface two channels (from the information displayed by the
devtree
command).
NOTE:
The EFI driver handle values change on every boot.
TIP:
From the
drvcfg
command, record these two pieces of information for each channel
of each SCSI interface for parameters to be changed:
•
Drv
(the EFI driver handle)
•
Ctrl
(the controller handle)

At the EFI Shell prompt, enter:
Shell> drvcfg -s drvr_handle cntrl_handle
where
•

The handle of the driver that controls the channel with the SCSI ID you
want to display or change
•
cntrl_handle

to display or change
For channel A of this SCSI interface, enter:
Shell> drvcfg -s 45 18
The EFI SCSI Setup Utility starts and its main menu appears, showing a list of all the EFI
