Yes the CPU installed is 64bit but the chipset present in the
notebook are not of 64bit still many of the chipset designer haven't
degines their chipset which support 64bit Operating system. The chipset
for about is Graphic card, Sound Card, Wired and Wireless network card,
also motherboard buses should have the feature that it should support
the 64 bit data transfer rate. I'm sorry to inform you that due the
various reasons I have mentioned above the drivers are unavailable for
the 64 bit Edition of Windows because the drivers for the chipset has
not been developed for Graphics, Modem and other chipset.
