Adaptec Inc, Milpitas, California is claiming to be first company to market SCSI software compatible with Microsoft’s layered device driver architecture for OS/2, and the company also introduced its Advanced SCSI Programming Interface/2 software for OS/2: ASPI/2 and LADDR form a bus-independent SCSI software architecture with built-in support for up to seven SCSI hard disks, and several options for other peripherals; ASW-1420 1.21, which provides SCSI disk support and an ASPI/2 layer that interfaces with a range of LADDR device modules, works with Adaptec’s AHA-154X – AT to SCSI – and AHA-1640 – Micro Channel to SCSI – host adaptors; the device modules provide support for other peripherals including SCSI tape, write-once optical disks, CD-ROM, digital audio tape, and printer; typical applications for the software are file servers and multi-user systems; the company says that faster system performance is achieved through the ASW-1420 1.21’s support of multitasking input-output which overlaps input-output requests to peripherals, and bus mastering, to reduce the processor’s involvement in the accessing of information.
