NAME

adp − low-level module for Adaptec 7870/7871/7872/7880/7881/7882-based SCSI controllers

SYNOPSIS

adp@reg

AVAILABILITY

x86

DESCRIPTION

The adp module provides low-level interface routines between the common disk/tape I/O system and SCSI (Small Computer System Interface) controllers based on the Adaptec AIC-7870P and AIC-7880P SCSI chips. These controllers include the Adaptec 2940, 2940W, 2940U, 2940UW, 3940, and 3940W, as well as motherboards with embedded AIC-7870P and AIC-7880P SCSI chips.

The adp module can be configured for disk and streaming tape support for one or more host adapter boards, each of which must be the sole initiator on a SCSI bus. Auto-configuration code determines if the adapter is present at the configured address and what types of devices are attached to the adapter.

The device address, reg, is derived from bits 3-7 of the PCI device number.
