Abstract

A controller initializing device and method is configured to initialize controllers. When a device is powered on, a basic input and output system of the device initializes a first chip of the device. The basic input and output system starts a power on self test and initializes a first controller of the device. The basic input and output system outputs a trigger signal when the power on self test of the basic input and output system ends. A baseboard management controller of the device accesses the first controller when the baseboard management receives the trigger signal.

First claim

What is claimed is:

1. A controller initializing device comprising:
a first chip programmed to include a basic input and output system;
a second chip coupled to the first chip;
a first controller coupled to the first chip; and
a baseboard management controller coupled to the first chip and the first controller, the baseboard management controller configured such that in event the controller initializing device is powered on, the basic input and output system initializes the second chip, the basic input and output system starts a power on self test and initializes the first controller, the basic input and output system outputs a trigger signal when the power on self test of the basic input and output system ends, the baseboard management controller accesses the first controller when the baseboard management controller receives the trigger signal.

2. The controller initializing device as claim 1 , wherein the controller initializing device is a server.

3. The controller initializing device as claim 2 , wherein the second chip is a central processing unit.

4. The controller initializing device as claim 1 , wherein the first controller is a temperature sensor.

5. The controller initializing device as claim 1 , further comprising a second controller, wherein the second controller is coupled to the first chip and the baseboard management controller, the basic input and output system starts the power on self test and initializes the second controller, the basic input and output system outputs the trigger signal in event the power on self test of the basic input and output system ends, the baseboard management controller accesses the second controller when the baseboard management controller receives the trigger signal.

6. The controller initializing device as claim 5 , wherein the second controller is a speed sensor.

7. A controller initializing method, comprising:
predefining a powered on mode of a controller initializing device;
initializing a chip of the controller initializing device corresponding to the powered on mode by a basic input and output system;
starting a power on self test and initializing controllers by the basic input and output system;
ending the power on self test and outputting a trigger signal to a baseboard management controller of the controller initializing device;
accessing the controllers by the baseboard management controller.
