IDG News Service - Microsoft Corp. executives urged hardware makers yesterday to build drivers for the upcoming 64-bit releases of Windows, lest the adoption of 64-bit computing be held back by hardware incompatibilities.
The software maker announced at its annual Windows Hardware Engineering Conference (WinHEC) that it will deliver versions of Windows XP and Windows Server 2003 for 64-Bit Extended Systems in the fourth quarter. Previously, the company had only said it would ship the software in the second half of the year.
Makers of hardware such as network interface cards, modems, graphics cards, printers and scanners have to develop 64-bit drivers for their products to work with the operating systems, Microsoft said.
In separate speeches at WinHEC in Seattle, Microsoft Chairman and Chief Software Architect Bill Gates and Group Vice President Jim Allchin called on the audience of hardware makers to develop drivers for the 64-bit operating systems.
"There's a real call to action from us here. Let's make sure the device drivers are not a gating factor for people moving to 64-bit," Gates said.
"The app compatibility is good; the OS support is comprehensive. What's the one thing we need? 64-bit drivers. You guys have got to do the 64-bit drivers," Allchin said.
The 64-bit system processes more data per clock cycle, allows greater access to memory and speeds numeric calculations. Microsoft has worked with processor maker Advanced Micro Devices Inc. to develop the 64-bit operating systems for its Athlon and Opteron chips. Athlon is meant for use in desktop computers and Opteron for server systems; 64-bit operating systems have been available on the competing Unix platform for years.
Microsoft expects significant adoption of 64-bit systems, and by the end of 2005, all of the processors sold by AMD and the majority of processors sold by Intel Corp. will support 64-bit computing, Gates predicted. On the server, 64-bit will be common within the next couple of years, and desktop users will want to reap the benefits of the capabilities, he said. Intel earlier this year followed rival AMD in announcing a processor with 64-bit extensions technology.
Tim Wright, director of strategic marketing at Sunnyvale, Calif.-based AMD, agreed with Gates' prediction. "By the end of 2005, all we will be shipping is AMD 64," he said.
One key benefit of 64-bit extension technology and Microsoft's 64-bit operating systems is that applications written for 32-bit computers will still work with processors that can run 64-bit software. However, that isn't true for device drivers, said Tom Phillips, general manager of Microsoft's hardware experience group.
