DOCUMENT:Q142563 08-AUG-2001 [winnt] TITLE :Large IDE Drive Support Using AMI Disk Extender PRODUCT :Microsoft Windows NT PROD/VER::3.1,3.11,3.5,3.51 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51 - Microsoft Windows NT Server versions 3.5, 3.51 - Microsoft Windows 95 - Microsoft Windows for Workgroups version 3.11 - Microsoft Windows versions 3.1, 3.11 ------------------------------------------------------------------------------- SUMMARY ======= Many computers cannot access more than 528 MB of data on IDE drives, which is by design. However, some third-party software programs can allow access of data beyond the 528 MB limit such as On Track Disk Manager. Some hardware manufacturers have introduced enhancements to the BIOS and the IDE controllers so that data can be virtually accessed through Logical Block Addressing (LBA). If the hardware manufacturer of your computer does not provide this feature, you may want to upgrade your BIOS to the Disk Extender. For more information, contact American Megatrends, Inc., at (800) 828-9264 or (404) 263-9381. MORE INFORMATION ================ Most large IDE drives support LBA. One of Disk Extender's preferred requirements is that the computer supports LBA for its IDE drives. If your computer does not provide this support, Disk Extender uses Block Transfer Mode for the IDE drives so that data can be accessed beyond 528 MB. Disk Extender works with any of the Microsoft operating systems and supports up to four IDE hard drives on a system. The following information lists additional features of the AMI Disk Extender: - Supports up to two IDE Controllers (primary and secondary). - Supports up to two IDE drives (master and slave) for each IDE controller, a total of four IDE drives. - Supports IDE LBA mode drives with capacities greater than 528MB. - Needs no additional support from the system BIOS. - Works with any system BIOS. - Derived from AMI BIOS. - Requires no configuration; auto detects and configures IDE drives.
