AlphaServer 800 Service Guide
Variable Attributes Description
ew*0_mode
(continued)
fastfd—Sets the default device to fast full duplex
100BaseT.
full—Set the default device to full duplex twisted
pair.
twisted-pair— Sets the default device to 10Base-
T (twisted-pair).
ew*0_protocols NV Determines which network protocols are enabled
for booting and other functions.
mop—Sets the network protocol to MOP: the
setting typically used for systems using the
OpenVMS operating system.
bootp—Sets the network protocol to bootp: the
setting typically used for systems using the
DIGITAL UNIX operating system.
bootp,mop—When the settings are used in a list,
the mop protocol is attempted first, followed by
bootp.
os_type NV Sets the default operating system.
vms or unix—Sets system to boot the SRM
firmware.
nt—Sets system to boot the AlphaBIOS
firmware.
pci_parity NV Disable or enable parity checking on the PCI bus.
On—PCI parity enabled.
Off—PCI parity disabled (default value).
Some PCI devices do not implement PCI parity
checking, and some have a parity-generating
scheme in which the parity is sometimes incorrect
or is not fully compliant with the PCI
specification. In such cases, the device functions
properly so long as parity is not checked.
pk*0_fast NV Enables fast SCSI devices on a SCSI controller to
perform in standard or fast mode.
0—Sets the default speed for devices on the
controller to standard SCSI.
