In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This enables support for the Atari ACSI interface. The driver
supports hard disks and CD-ROMs, which have 512-byte sectors, or can
be switched to that mode. Due to the ACSI command format, only disks
up to 1 GB are supported. Special support for certain ACSI to SCSI
adapters, which could relax that, isn't included yet. The ACSI
driver is also the basis for certain other drivers for devices
attached to the ACSI bus: Atari SLM laser printer, BioNet-100
Ethernet, and PAMsNet Ethernet. If you want to use one of these
devices, you need ACSI support, too.

To compile this driver as a module, choose M here: the
module will be called acsi.
