How does the hardware fit into a 64-bit system? WinXP 64 Pro RC2 is a 64-bit operating system. The commonly used 32-bit hardware drivers can't work under it. Fortunately, Microsoft has built 64-bit drivers for most mainstream hardware in the system, like the author. The sound card and network card integrated with the MSI MS-6072 motherboard and the FX5900 graphics card can be driven normally. Of course, there are exceptions. The author's Tianmin TV card is only displayed as an unknown multimedia device in the device manager. Currently, there is no 64-bit driver, so it cannot be used.

It is necessary to install the 64-bit driver provided by nVIDIA and install it on the official website. Tip: Athlon 64 and Intel EM64T implement 64-bit technology AMD64 chose to develop 32-bit 64-bit processor technology, called x86-64. The way x86-64 is implemented is to add support for 32-bit processors based on 64-bit processors. The finished product is the AMD64 processor we are familiar with, including Athlon 64 and Athlon FX. Intel 64-bit processor technology adds support for 64-bit extensions based on current IA-32 architecture processors. Soon, we can see the civilian-class Intel 64-bit processor in kind.
