NAME

pcscsi − low-level module for the AMD PCscsi, PCscsi II, and PCnet-SCSI  PCI-to-SCSI bus adapters

SYNOPSIS

pcscsi@ioaddr,0

AVAILABILITY

x86

DESCRIPTION

The pcscsi module provides low-level interface routines between the common disk/tape I/O subsystem and the Am53C974 (PCscsi), Am53C974A (PCscsi II), and Am79C974 (PCnet-SCSI) Small Computer System Interface (SCSI) controllers. 

The pcscsi module can be configured for disk and streaming tape support for one host bus adapter device. Each host bus adapter device must be the sole initiator on a SCSI bus. Auto configuration code determines if the adapter is present on the PCI bus, what its configuration is, and what types of devices are attached to it. 

As these are PCI devices, any configuration is done through the PCI BIOS.  Generally these settings can be accessed through a CMOS utility. 

CONFIGURATION

The driver attempts to initialize itself in accordance with the configuration the PCI BIOS assigned to the chip. 

While there is information found in the configuration file, pcscsi.conf, this information is used only by the I/O subsystem.  There are no user-configurable options. 

FILES

/kernel/drv/pcscsi.conf configuration file for the pcscsi driver.
