Intel® Application Accelerator
Information on using hard drives larger than 137GB (48-bit LBA)
You can use the Intel® Application Accelerator to access the full capacity of hard drives that are larger than 137GB on supported Intel® chipsets with a supported operating system. The Intel Application Accelerator supports hard drives that are greater than 137GB -- which is also referred to as 48-bit logical block addressing (LBA).
Windows* XP, Windows 2000, Windows Me, Windows 98 SE, Windows 98, and Windows NT* 4.0 do not provide native support for hard drives that are larger than 137GB. 48-bit LBA support can be added with Windows* XP Service Pack 1* and Windows* 2000 Service Pack 4*. Please contact Microsoft* for additional information. In order to enable hard drives larger than 137GB, you will need to install the Intel Application Accelerator or install a 3rd party 48-bit LBA controller card.
