Corrective Action / Resolution
Intel Server Board SE7221BK1-E system BIOS will be updated to properly indicate the following information screens
augment memory configuration characteristics for the Intel Server Board SE7221BK1-E and Intel Server Platform
SR1425BK1-E customers.
– Total physical memory populated in the system
– Total memory dedicated to motherboard resources
– Total memory reported as available to the operating system
This information will align to the INT15h E820h standard that BIOS uses to communicate memory usage to the
operating system. This BIOS feature will clarify the memory subsystem support and usage for the end user.
