CONFIGURATION
9.1.8.
BERR# Driving Policy for Target Bus Errors
A Pentium Pro processor bus agent can be enabled to drive the BERR# signal if the addressed
(target) bus agent detects an error. After active RESET#, BERR# signal driving is disabled on
target bus errors. It may be enabled under software control. The Pentium Pro processor does not
drive BERR# on target detected bus errors. The Pentium Pro processor does support observation
and machine check entrance.
9.1.9.
Bus Error Driving Policy for Initiator Internal Errors
On internal errors, a Pentium Pro processor bus agent can be enabled to drive the BERR# signal.
After active RESET#, BERR# signal driving is disabled on internal errors. It may be enabled
under software control.
9.1.10. BERR# Observation Policy
The BERR# input receiver is enabled if A9# is observed active on the active-to-inactive transi-
tion of RESET#. The Pentium Pro processor does not support this configuration option.
9.1.11. BINIT# Driving Policy
On bus protocol violations, a Pentium Pro processor bus agent can be enabled to drive the
BINIT# signal. After active RESET#, BINIT# signal driving is disabled. It may be enabled un-
der software control. The Pentium Pro processor relies on BINIT# driving to be enabled during
normal operation.
9.1.12. BINIT# Observation Policy
The BINIT# input receiver is enabled for bus initialization control if A10# is observed active on
the active-to-inactive transition of RESET#. The Pentium Pro processor relies on BINIT# obser-
vation being enabled during normal operation.
9.1.13. In-order Queue Pipelining
Pentium Pro processor bus agents are configured to an In-order Queue depth of one if A7# is
observed active on RESET#. Otherwise it defaults to an In-order Queue depth of eight. This
function cannot be controlled by software.
