- * Amiga specific bits in the battery-backedup ram.

- * Bits 0 to 31, inclusive

- (*
- * AMIGA_AMNESIA
- *
- * The battery-backedup memory has had a memory loss.
- * This bit is used as a flag that the user should be
- * notified that all battery-backed bit have been
- * reset and that some attention is required. Zero
- * indicates that a memory loss has occured.

-
- (*
- * SCSI_TIMEOUT
- *
- * adjusts the timeout value for SCSI device selection. A
- * value of 0 will produce short timeouts (128 ms) while a
- * value of 1 produces long timeouts (2 sec). This is used
- * for SeaCrate drives (and some Maxtors apparently) that
- * don`t respond to selection until they are fully spun up
- * and intialised.
- *)

-
- (*
- * SCSI_LUNS
- *
- * Determines if the controller attempts to access logical
- * units above 0 at any given SCSI address. This prevents
- * problems with drives that respond to ALL LUN addresses
- * (instead of only 0 like they should). Default value is
- * 0 meaning don't support LUNs.

- * SHARED_AMNESIA
- *
- * The battery-backedup memory has had a memory loss.
- * This bit is used as a flag that the user should be

- * indicates that a memory loss has occured.

- (*
- * SCSI_HOST_ID
- *
- * a 3 bit field (0-7) that is stored in complemented form

-
- (*
- * SCSI_SYNC_XFER
- *
- * determines if the driver should initiate synchronous
- * transfer requests or leave it to the drive to send the
- * first request. This supports drives that crash or
- * otherwise get confused when presented with a sync xfer
- * message. Default=0=sync xfer not initiated.

- (*
- * See Amix documentation for these bit definitions
- *

-
- (*
- * SCSI_FAST_SYNC
- *
- * determines if the driver should initiate fast synchronous
- * transfer requests (>5MB/s) instead of older <=5MB/s requests.
- * Note that this has no effect if synchronous transfers are not
- * negotiated by either side.
- * Default=0=fast sync xfer used.

-
- (*
- * SCSI_TAG_QUEUES
- *
- * determines if the driver should use SCSI-2 tagged queuing
- * which allows the drive to accept and reorder multiple read
- * and write requests.
- * Default=0=tagged queuing NOT enabled
- *)
-
- scsiTagQueuesAddr * = 70;
