Porting ZT 5550 HA Applications to
PICMG 2.12 F
The PICMG 2.12 base API (described in Chapter 6) and IPMI replace the functionality of the Host
Controller API used with the ZT 5550 system master board. This appendix provides information
for porting applications that were written for the ZT 5550 to a PICMG 2.12 based system. The
following table summarizes the changes in the functionality.
