Enter the show envar command to display EV settings.
The commands set os_type openvms or set os_type unix selects the corre-
sponding operating system (OpenVMS or UNIX) and the corresponding SRM
console. The command set os_type nt selects the AlphaBIOS console and Windows
NT becomes the default operating system. The os_type EV takes effect only after a
subsequent reset or power-up.
The ew*0_mode environment variable is used to set an Ethernet controller to run
an AUI, ThinWire, or twisted-pair Ethernet network. For example, issuing a set
ew*0 bnc selects the ThinWire device type.
Entering set pk*0_fast enables fast SCSI mode. Other possible pk*0 EVs
include pk*0_host_id, which specifies the default value for a controller host bus
node ID, and pk*0_soft_term, which enables or disables SCSI terminators on
systems that use the QLogic ISP1020 SCSI controller.
Use the command set bootdef_dev to set the name of the device on which the
system software has been loaded.
When you issue a set boot_osflags, you pass information to the boot command.
For example, entering set boot_osflags a loads the operating software from the
specified boot device (autoboot), and boots to multiuser mode when the operating
system is DIGITAL UNIX. Refer to your operating system documentation for more
information on os_flags definitions.
Issue a set console graphics command to set the console mode to graphics. The
other option is serial. This console EV takes effect only after a subsequent reset or
power-up.
For more information on environment variables, see the System Drawer User's
Guide.
