6.44.5IPMB Services

The system BIOS provides real-mode calls to Read, Write, and Master Read/Write the IPMB. The Read and Write functions are used for all master/slave I2C devices on all buses.

IPMB Services have the following characteristics:

•They are 16-bit real-mode (EMM386 cannot be running).

•They can be used for all IPMB commands.

•They can be used to communicate with any I2C controller.

•If the carry flag is set, the interface has broken or timed-out.

•The caller is responsible for providing proper inputs. No sanity check is provided.

•The caller is responsible for checking completion code.
