Appendix C • 69
• Block Transfer (BT) – Zircon CP’s BT interface provides 128-byte
(each) Host-to-BMC and BMC-to-Host FIFOs. The interface provides
the three-register set specified in the IPMI specification – BT_CTRL,
HOST2BMC/BMC2HOST, and BT_INTMASK. As in the KCS interfaces,
each register’s system address is programmable. The FIFOs remain
IPMI v1.1 compliant while providing an operational extension to the
specification for queued operation. More than one, or even two
messages may be queued in the FIFOs at a time, thus reducing
system overhead and lost processing power.

C.1.3 Serial EEPROMs
The cPCI-6765 provides two serial EEPROMs to store the SEL and FRU
information. Each SEL record uses 16 bytes so there are 500 records for
SEL storage. The slave address for SEL is 0xAC. FRU is used to store the
VPD data. The slave address for FRU is 0xAE.
C.1.4 Supported IPMI functions
QLogic provides a firmware suite supporting the Intelligent Platform
Management Interface (IPMI) specification v 1.0, including the Intelligent
Platform Management Bus (IPMB). The following IPMI commands are
implemented. These commands may be used by a host device drivers
and/or application software to communicate with Zircon and/or sensors
and other management controllers in the system. Refer to the IPMI v1.0
specification for a complete description of these commands.
