To take full advantage of 64-bit processors and operating systems, we'll need faster data throughput and Ultra320 SCSI is one of the solutions. Adaptec is looking to the future with its new Ultra320 SCSI product, which combines support for 64-bit operating systems and Adaptec's Ultra320-ready Extensible Firmware Interface (EFI) driver. The driver connects Ultra320 SCSI ASICs and host bus adapters to systems with 64-bit processors. Today's 32-bit systems use BIOS for hardware initialization, boot operations, and configuration utilities that reside in the Electrically Erasable Programmable Read Only Memory (EEPROM). Adaptec says that EFI allows these capabilities to reside not only in the EEPROM but in a hard disk, floppy drive, or CD ROM, enabling the EFI driver to be loaded from any of the devices and eliminating the need to flash a new BIOS onto the motherboard. Adaptec now offers 64-bit drivers for Ultra160 and Ultra320 SCSI.
