Important notice on installing Windows ® XP 32-bit version
If you install Windows ® XP 32-bit version Operating System (OS), the limitation
of this OS version is that it may reserve a certain amount of memory space for
system devices. We recommend that you install less than 3 GB system memory
if you would like to work under Windows ® XP 32-bit version OS. The excess
memory installation will not cause any usage problem, but it will not give users
the benefit of manipulating this excess memory space.
