A
2.4.35 CSCONFV—CAPTURED SYSTEM CONFIGURATION VALUES REGISTER
Address Offset:
B4–B5h
Default:
XXh (X=Captured During hard reset)
Attribute:
Read Only
The register reports how the system is set up for certain functions. The values in this register are captured on
the rising edge of RESET#.
7
In-Order Queue Depth 1 Select. 1=Depth of 8. 0=Depth of 1. The value in this bit is driven on
A7#. Pentium Pro processors use an in-order queue depth of 8 if this bit is 1.
6
1M Power-on Reset Vector Select. 1=1 Mbyte. 0=4 Gbyte. The value in this bit is driven on A6#.
Pentium Pro processors use the 1 Mbyte reset vector if this bit is 1.
5
FRC Mode Enable. 1=Enable. 0=Disable. The value in this bit is driven on A5#. Pentium Pro
processors enter FRC enabled mode if this bit is 1.

Description
For the 82454GX, see the EXERRCMD Register (offset C0–C3h) for additional details.
Caution: Programming the corresponding output enable bit in the EXERRCMD Register must be
consistent with the value in this bit captured from the host bus. Otherwise, incorrect system
operations will result.
