64-bit Win XP 7 issues I care about

WinXP 64 Pro full name Windows XP 64bit Edition, Microsoft's operating system designed specifically for Opteron/Athlon 64 and Intel EM64T. It can meet the needs of future massive memory and floating point performance applications, with faster code execution efficiency. In the face of the new operating system, as a user, I was also excited about the expectation, with a little worry, with some questions... After getting WinXP 64 RC2, I took a lot of questions that I care most about. try out.

Remember to take the installation serial number inside and use it later. Must be activated to use 360 days, otherwise there is only a 14-day period.

32 Wei core "broken"?

install WinXP 64 Pro RC2, it first detects whether the CPU meets the requirements. When a 32-bit CPU is detected, it "relentlessly" refuses to install and cannot be installed in virtual machine software such as VMWare. It seems that Microsoft has not considered 64-bit WinXP to be compatible with 32-bit CPUs. That is to say, most of the current computers are "out of the box" with WinXP 64.

What is the difference between installations?

downloaded ISO image dials, reboot the system with the CD boot installation interface, WinXP 64 Pro RC2 installation interface and the installation process is very similar to the 32-bit version of WinXP. When installing SATA hard disk under WinXP 64 Pro RC2, you need to pay attention to it. When installing SATA hard disk under 32-bit WinXP, some motherboards need to load the SATA driver that comes with the disk. This is also true under WinXP 64 Pro RC2. I used the VIA KT800+SATA hard drive, so first log in to the VIaA official website to download the corresponding 64-bit driver (VIA_HyperionPro64_V099.zip file). After decompressing, copy all the files in the HyperionPro64-099VIARaidDrvDisk directory to the floppy disk. When installing WinXP 64 Pro RC2, when the screen prompts "Press F6 if you need to install a third party SCSI or RAID driver...", press the "F6" button, press the "S" button to insert the floppy disk you just made to load the driver. The program, in a short while, SATA hard drive can be found. After the file copy is complete, the installation wizard will prompt you to enter the serial number, then fill in the serial number previously copied with the pen.

Coexisting with 32-bit WinXP? I

PC configuration to AMD64 3200 +, WinXP 64 Pro RC2 entire installation process lasted about 40 minutes, is slightly slower compared to the 32-bit version WinXP. The installer is very smart, it allows the original operating system in the computer to coexist with it. For example, the original C drive has a 32-bit WinXP, WinXP 64 Pro RC2 is successfully installed on another hard drive, and is added to the boot entry. A "Windows XP x64 Edition" option. How to adapt the hardware

64-bit system?

WinXP 64 Pro RC2 is a 64-bit Caozuoxitong, the commonly used 32-bit drivers for hardware does not work properly under it, fortunately Microsoft has built most of the mainstream hardware in the system 64 Drivers, such as the author's MSI MS-6072 motherboard integrated sound card and network card, FX5900 graphics card, etc. 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. In short, the overall compatibility of WinXP 64 Pro RC2 hardware is similar to that of 32-bit WinXP, as long as it is not too different hardware can achieve the most basic functions.

to full performance hardware, entirely dependent Caozuojitong comes with hardware drivers is not enough, for example, to make the author of FX5900 graphics card in the game (such as DOOM3, Half-Life 2, etc.) Smooth operation (the default driver does not include OpenGL1.4 required for games such as DOOM3), you must install the 64-bit driver provided by nVIDIA, and download it after downloading from the official website.

Tips: Athlon 64 and Intel EM64T achieve 64-bit

AMD64 technology to the development of selected backward compatible with 32-bit 64-bit processor technology < Br>, called x86-64. The x86-64 implementation is based on the addition of support for 32-bit processors on a 64-bit processor. The finished product of this technology is the familiar AMD64 processor, including Athlon 64 and Athlon FX. . Intel 64-bit processor technology
is based on the current IA-32 architecture processor has added 64bit extension support. Soon, we can see the civilian-class Intel 64-bit processor in kind.

Can a 32-bit program run?

This is indeed a worthy concern, if 32-bit programs can not be compatible with 64-bit system, then all of a sudden so much software to achieve 64-bit upgrade, too difficult. In WinXP 64 Pro, Microsoft provides a subsystem called WOW64 (Windows-32-on-Windows-64), which provides an analog environment for existing 32-bit applications, making most 32-bit applications unnecessary. The changes run smoothly on the 64-bit version of Windows. In order to explain the problem more intuitively, the author randomly tested several commonly used 32-bit applications and games, and the compatibility is shown in Table 1.

commonly used 32-bit applications through the WOW64 subsystem run well, and the performance loss is very small, especially for mainstream games currently support very very satisfied. Everyone notices that any application software related to virtual devices, such as Alcohol, daemon, etc., is refused to install. It seems that if you want to continue to use the virtual drive in WinXP 64 Pro, you only have to wait for the new 64-bit version. Realplayer 10 Simplified Chinese version will refuse to install under WinXP 64 Pro RC2, but you can use Storm Video
5.0 instead. Although the Chinese input method 4.2 can run smoothly, it can't input Chinese in pure 64-bit application software such as IE for 64bit, and Microsoft's own "Microsoft Smart Pinyin" can.

Careful users may also find this phenomenon when installing the application software. By default, the 32-bit application software is installed in the "Program Files (x86)" directory, and the 64-bit application software is installed in the "Program". Files directory. Open the Task Manager and you will see a number of programs with the (*32) flag in the process list. These are the flags used by the system to distinguish between 32-bit applications.

Since WinXP64 is still in the testing stage, there is no 64-bit anti-virus software installed yet. I have tried the 32-bit version of "Rising 2005" anti-virus software. I am very lucky, whether it is Rising real-time monitoring. Still anti-virus, the operation is normal. This can be used for the time being before the 64-bit Rising stand-alone version has not come out (it is reported that Rising and Jinshan will soon launch 64-bit anti-virus software).

64-bit What are the advantages?

can be seen from Table 1, although the 64-bit WinXP system 32 are preferably compatible with the program, but this does not reflect the advantages of 64-bit system, but also from the 3DMark
In terms of test scores, the performance is very low. Isn't the 64-bit system better, but worse? Actually, this is because the current 64-bit applications are still very few, and the method of testing the performance of 64-bit systems is different from that of 32-bit systems, so there will be no rise and fall. However, Sciencemark.org has now launched ScIEnceMark 2 specifically for 64-bit Windows. It takes advantage of the 64-bit system to get a more accurate system score. This version already supports Pentium 4 EM64T and AMD 64-bit processors. Interested friends can download it at http://www.scIEncemark.org

Is there any change in the Internet?

The author uses ADSL fixed IP Internet access, in WinXP 64 Pro RC2 can be directly configured according to the 32-bit WinXP Internet settings, in the "Control Panel" /"Network and Internet Connections" /"Network Connections" configuration Open the connection properties and fill in the IP, gateway, mask, DNS and other parameters provided by the telecom. The tools for browsing the web can choose IE6 or a third-party browser (such as Firefox) that comes with the system. It should be noted that since IE6 for 64-bit is still a beta version, there are fewer plug-ins for it (including the Flash
plug-in), so it may not be able to browse Flash and online video playback in IE6 for 64-bit version. Wait, the LAN settings and the 32-bit WinXP settings are the same, so I won't go into details here. According to the author's test, WinXP 64 Pro RC2 and 32-bit WinXP SP2 peer-to-peer network interconnection and shared Internet access are normal.
