USB devices can also be installed in Windows

The WinXP pro full name, Windows XP 64bit Edition, is a Microsoft operating system designed specifically for Opteron/athlon 64 and Intel EM64T. It can meet the future needs of massive memory and floating-point performance applications, with faster code execution efficiencies. In the face of the new operating system, I as a user, also in the excitement of anticipation, with a trace of worry, with some doubt ... After getting WinXP RC2, with my most concerned about the issue of a trial.

Activation technology We're already familiar with it.

Complete the online registration on the http://www.microsoft.com/china/windowsxp/64bit/evaluation/default.mspx webpage, fill in the correct email address, So Microsoft will send you a copy containing WinXP Pro RC2 download Address of the mail, by mail instructions download ISO. Remember to put the inside of the installation serial number with notes down, will be used later. Must be activated to use 360 days, otherwise only 14 days of time.


32-bit core "broken"?

Install WinXP Pro RC2, which first detects if the CPU meets the requirements. When a 32-bit CPU is detected, it "ruthlessly" rejects the installation and cannot be installed in virtual machine software such as VMware. It seems that Microsoft has not considered the 64-bit WinXP to be compatible with the 32-bit CPU, that is to say, the vast majority of computers are and WinXP 64 "missed."

How is the installation different?

The ISO image will be downloaded, restart the system with CD-ROM boot into the installation interface, WinXP Pro RC2 Installation interface and installation process with the 32-bit version of the WinXP very similar. When installing SATA drives under WinXP Pro RC2, it is necessary to note that SATA drives are installed under 32-bit WinXP and some motherboards need to load the SATA drivers that shipped with the disk, as well as under WinXP Pro RC2. The author is using the VIA kt800+sata hard drive, so first login to VIAA official website download the corresponding 64-bit driver (via_hyperionpro64_v099.zip file), After decompression, copy all the files in the Hyperionpro64-099viaraiddrvdisk directory to the floppy disk. When installing WinXP Pro RC2, when the screen prompts "press F6 if you need to install a third party SCSI or RAID driver ..." click "F6" button, press "S" key to insert the floppy disk just made to load drive Move the program, in a moment, SATA hard drive can be successfully found. After the file copy is complete, the Installation wizard prompts for the serial number, and then fills in the serial number that was previously copied from the pen.

Coexist with 32-bit WinXP?

The author's PC is configured to AMD64 3200+,WINXP Pro RC2 The entire installation process lasts about 40 minutes, slightly slower than the 32-bit version of WinXP. The installer is very intelligent, it allows the original operating system to coexist with the computer, such as the author C disk originally had a 32-bit WINXP,WINXP Pro RC2 was successfully installed on another hard drive, and in the boot to add a "Windows XP x64 Edition" Options.
How does the hardware fit into the 64-bit system?

WinXP Pro RC2 is a 64-bit operating system, the current 32-bit hardware driver can not work under it, the good news is that Microsoft has built most of the mainstream hardware in the system 64-bit driver, like the author's MSI MS-6072 motherboard integrated sound card and network card, FX5900 graphics and so on are able to drive normally. Of course, there are exceptions, the author of the day-sensitive TV card in the Device Manager is only shown as unknown multimedia equipment, currently no 64-bit driver, therefore can not be used. In short, WinXP Pro RC2 hardware overall compatibility and 32-bit WinXP similar, as long as not too alternative hardware can achieve the most basic functions.

To play the full performance of the hardware device, relying entirely on the operating system's own hardware driver is not enough, such as to let the author's FX5900 graphics card in the game (such as DOOM3, Half Life 2, etc.) fluent running (the default driver does not contain the DOOM3 and other games required for the OpenGL1.4), it is necessary to install Nvidia provided 64-bit driver, to the official web site download after installation.

Small knowledge: Athlon 64 and Intel EM64T implement 64-bit technology

AMD64 has chosen to develop a 64-bit processor technology that is backward-compatible 32-bit, known as x86-64. The x86-64 implementation is to add support for a 32-bit processor based on a 64-bit processor, which is the finished product of the AMD64 processor we already know, including Athlon 64 and Athlon FX. The Intel 64-bit processor technology adds extended support for 64bit based on the current IA-32 architecture processor. Soon, we can see the civilian level of the Intel 64-bit processor in kind.
