[. . . ] 0662a10. txt 3 1/2-INCH 1 GB LOW PROFILE AT DISK DRIVE 0662 MODEL A10 ______________ AN OEM OFFERING FROM IBM The award-winning IBM 0662 disk drive is now available to users with AT-based systems. [. . . ] When attached to a Local Bus (VESA or PCI), data rates to 13 MB/sec are supported, making the Model A10 an excellent choice for high-performance workstation applications. Using the Duplex Mode, the 0662 Model A10 is downward compatible with existing AT BIOS systems that cannot address greater than 526 MB. In this mode, the system addresses the drive as if it were two 500 MB drives No additional device drivers are required.
