- depends on ATARI && BROKEN
- ---help---
- 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.

- If you have a ACSI device that supports more than one LUN (Logical
- Unit Number), e.g. a CD jukebox, you should say Y here so that all
- will be found by the ACSI driver. An ACSI device with multiple LUNs
- acts logically like multiple ACSI devices. The vast majority of ACSI
- devices have only one LUN, and so most people can say N here and
- should in fact do so, because it is safer.

- If you have an Atari SLM laser printer, say Y to include support for
- it in the kernel. Otherwise, say N. This driver is also available as
- a module ( = code which can be inserted in and removed from the
- running kernel whenever you want). The module will be called
- acsi_slm. Be warned: the driver needs much ST-RAM and can cause
- problems due to that fact!
