Configuring Your System
3–19
Table 3–9: SRM Environment Variables (continued)
Variable Description
ewa0_protocols Determines the Ethernet protocol , which can be either MOP or
BOOTP. MOP is the default.
kbd_hardware_type Selects the type of keyboard on your system. Possible values are
LK411 or PCXAL. PCXAL is the default.
language The language environment variable associates language n to the
system (where n is the number of the language shown below). You
can have the system prompt you for the language using the
following command:
>>>set language 0
and then
>>>init.
Select the desired language. Type
>>>init
again,
then power cycle the system.
os_type Identifies the operating system being used on the system. Values
of OpenVMS, OSF, UNIX, or VMS cause the SRM console to
load.
pka0_fast A value of 0 sets the SCSI mode to slow (5 MB/sec); a value of 1
sets the SCSI mode to fast (10 MB/sec). Digital UNIX operating
system users also must edit the configuration file and rebuild the
kernel.
pci_parity This variable controls PCI parity checking at the PCI bridge chip.
Parity checking is performed if on, disabled if off, and dependent
on the SCSI controller revision if sniff. Default is off.
Certain PCI adapters have been known to generate bad parity on
the PCI under certain loading conditions, which results in system
errors.
Ensure that your specific PCI configuration will operate correctly
prior to turning on parity checking.
tga_sync_green This variable is used to control the composite video signal for
monitors on the ZLXp controller that cannot detect the presence of
composite video or v/h signals. The possible values are:
1 – composite video for first ZLXp.
2 – composite video for the second ZLXp.
3 – composite video for the first and second ZLXp.
Adding ISA Bus Devices
ISA Configuration Utility
ISA devices cannot be probed for configuration information by the Digital UNIX or
OpenVMS operating system. Therefore, you must enter ISA option information manually
using the ISA configuration utility. Run this utility before installing a new ISA option
