IPMI Block Transfer Interface Registers
The host can access the IPMC via the two Block Transfer (BT) Interfaces 0 and1. Both are
fully compliant to the IPMI specification V1.5. Each BT interface provides the following
registers.

Buffer Register
This register provides access to an IPMC−to−Host and Host−to−IPMC buffer. The buffer
has a size of 64 bytes and contains command streams between host and IPMC.

Ethernet Switch Management Registers
The following registers consitute an Ethernet management interface accessible by the
host. The registers allow to configure and control the operation of the on−board Ethernet
switch. The Ethernet management interface conforms to the IEEE 802.3 management draft
standard. The base address of these registers is 0x150.
