Opening Ports in XP Service Pack 2

If you're getting ready to update to the Windows XP Service Pack 2, Microsoft has just released a guide on application compatibility. If you're concerned about which applications you might have problems with, it's worth a look. For most home users, installing and running with Windows XP Service Pack 2 is not a problem. However, some Internet applications may need specific ports opened in the new Windows Firewall. Last week we showed how to tell the firewall about new applications, but sometimes you also need to specify additional ports. In our example here, we are going to open ports for...

What is XP 64 Bit Edition?

Microsoft is making a version of this operating system for those running x86-64 processors. Currently, that means anyone running the AMD Athlon64/FX/Opteron (hence the "extended" wording in the name). The short version of the name implies the likes of the 386 moving x86 to 32bit from 16bit, and the first 8086 used in the original IBM PCs extending the original architecture from 8bit to 16bit. AMD increased the size of the registers, added a few instructions, and kept its binary compatibility with all previous x86 programs. The real XP 64 Bit Edition is meant for Intel's Itanium, running the IA-64...

Windows XP 64-bit, a virtual minefield?

Granted, you’ll have to give it to Microsoft for often being overly optimistic about their accomplishments. As honestly what other company would be pitching a product that’s been delayed by almost two years and features nothing new but for 64-bit support like it is a quantum leap from the 32-bit version of Windows XP? In truth the 64-bit version of Windows XP is far from that, at best it is a Windows kernel with 64-bit extensions that works on a handful of systems with a very specific hardware configuration, or to be specific on hardware that has working 64-bit drivers....

Windows XP X64 goes gold

MICROSOFT HAS released the final version of Windows XP 64 to manufacturing, meaning that those with machines that have 64-32 bit processors in from AMD and latterly Intel can now see what the extra addressing brings to the party. No doubt people can also look forward to future service pack releases from Microsoft, but we mustn't be too churlish about this, even though the OS is long delayed. Only the most absurdly cynical would suggest that it's been delayed because Intel was hurriedly racing to catch up and make its chips similar enough to AMD64 processors to run the OS....

Application Problems in Windows XP SP2

Now that Windows XP Service Pack 2 (SP2) is available at Windows Update for online update of both the XP Home Edition and XP Professional Edition platforms, you need to be prepared for the changes you’ll see as a result of the security controls XP SP2 installs and activates by default. A query of Microsoft's XP SP2 Knowledgebase articles posted during the past 2 weeks turned up a laundry list of installation and device-related bugs, information about the affects of the now disabled Alerter and Messenger services, problems related to the enabled firewall, third-party network backup, and other application problems....

Athlon 64 and Windows XP 64 Bit Edition - This is the Beta

For the past week, I've been running Windows XP 64 Bit. This version is still a beta version of the OS. In other words, should you try this for yourself, don’t expect full functionality. What this 64-bit operating system does allow is the running of 64-bit programs. Unfortunately, at this point I have none of those. (If you have one, and can spare a license...) Let's begin with the hardware: the Athlon64/FX/Opteron has the ability to run in three modes. The first is "Legacy," which almost everyone is using right now. That's where you have a 32-bit O/S, and 32-bit...

Windows XP 64-Bit Edition

This is preview software. In other words, there are still a lot of kinks to work out, and very little driver support. ATi has stated their unwillingness to make special drivers for an operating system that is not final, and other hardware vendors have also been slow on the uptake. I can't really say I blame them--by the time this operating system goes "gold", they will have spent a lot of time creating drivers and support for very few users. The only thing to be gained is experience compiling for this modified kernel. Thankfully though, VIA, Silicon Image and...
