Compaq AlphaServer ES45 1B User Manual

5-68 ES45 Owner's Guide
5.14.19 pci_parity
The pci_parity environment variable disables or enables parity check-
ing on the PCI bus.
Some PCI devices do not implement PCI parity checking, and some have a par-
ity-generating scheme in which the parity is sometimes incorrect or is not fully
compliant with the PCI specification. A side effect of this behavior is that super-
fluous PCI parity errors are reported by the host PCI bridge. In such cases, the
device can be used as long as parity is not checked.
CAUTION: Disabling PCI parity checking on this system is not recommended
or supported.
Syntax
set pci_parity value
The options for value are:
on (default)
Enables PCI parity checking.
off
Disables PCI parity checking.
Example
P00>>> show pci_parity
pci parity on
