About the Product Capacity Representation
Standard
About Memory Capacity Representation
The memory capacity reported in the Chrome OS is less than the
actual capacity of memory.
This is because BIOS or a video adapter uses a portion of memory
or claims it for further use.
(E.g. For 1GB(=1,024MB) memory installed, OS(Windows, Chrome,
etc.) may report the capacity as 1,022MB or less)
