Techniques of retrieving bios data from BMC
In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system includes a BMC. The BMC receives, through a management platform on the BMC, a first part of initialization data from an initialization component of a host of the BMC. The BMC also receives an indication of a location at an initialization storage device of the host. The BMC then obtains access to the initialization storage device. The BMC reads a second part of the initialization data from the location of the initialization storage device.

13. The computer system of claim 8 , wherein the computer system further includes the host, including:
a second memory; and
second at least one processor coupled to the second memory and configured to:
generate, at the initialization component of the host, the initialization data;
write the second part at the location of the initialization storage device;
send the first part to the BMC; and
send the indication.
14. The computer system of claim 13 , wherein the second at least one processor is further configured to:
load the initialization component from the initialization storage device; and
allocate, by the initialization component, a storage space in the initialization storage device for storing the second part, wherein the location is associated with the storage space.
