The problem is expected to be fixed in an updated version of Lindenhurst arriving in the fourth quarter of 2004, sources said. Meanwhile, customers thinking of buying the new servers--the first with Intel chips that support 64-bit extensions--will be able to use the older PCI-X input-output slots or use adapters that have been certified not to be affected by the glitch. Intel declined to comment on unannounced products or the Lindenhurst glitch. However, a source familiar with the company's plans said Intel expects to publish the problem in an erratum notice Monday. The problem is the latest black eye for the chipmaker. Thursday, Intel confirmed its flagship 3.6GHz Pentium 4 processors are in short supply and its 4GHz sequel won't arrive in 2004 as earlier planned. And earlier this year, Intel delayed its "Dothan" chip for mobile computers and, later, the Alviso chipset. Intel also has to recall some Grantsdale chipsets for desktop computers with multimedia capabilities.
