NAME adp − low-level module for Adaptec 7870/7871/7872 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 andSCSI (Small Computer System Interface) controllers based on the Adap-

tec AIC-7870, AIC-7871, andAIC7872 SCSI chip. These controllers include the Adaptec 2940

and 2940W, and 3940 and 3940W, as well as motherboards with an embedded AIC-7870,

AIC-7871, and AIC-7872 SCSI chip.

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.

FILES /kernel/drv/adp.conf conﬁguration ﬁle for the adp driver. There are no user-
