5.5) 53c7xx=
Syntax: 53c7xx=<sub-options...>
These options affect the A4000T, A4091, WarpEngine, Blizzard 603e+,
and GForce 040/060 SCSI controllers on the Amiga, as well as the
builtin MVME 16x SCSI controller.
The <sub-options> is a comma-separated list of the sub-options listed
5.5.1) nosync
Syntax: nosync:0
Disables sync negotiation for all devices. Any value after the
colon is acceptable (and has the same effect).
5.5.2) noasync
5.5.3) nodisconnect
Syntax: nodisconnect:0
Disables SCSI disconnects. Any value after the colon is acceptable
(and has the same effect).
5.5.4) validids
Syntax: validids:0xNN
Specify which SCSI ids the driver should pay attention to. This is
a bitmask (i.e. to only pay attention to ID#4, you'd use 0x10).
Default is 0x7f (devices 0-6).
5.5.5) opthi
5.5.6) optlo
Syntax: opthi:M,optlo:N
Specify options for "hostdata->options". The acceptable definitions
are listed in drivers/scsi/53c7xx.h; the 32 high bits should be in
opthi and the 32 low bits in optlo. They must be specified in the
order opthi=M,optlo=N.
5.5.7) next
No argument. Used to separate blocks of keywords when there's more
than one 53c7xx host adapter in the system.

Use the following options to disable options in the SCSI driver.
Using amiboot for example.....
To disable Synchronous Negotiation....
amiboot -k kernel 53c7xx=nosync:0
To disable Disconnection....
amiboot -k kernel 53c7xx=nodisconnect:0
To disable certain SCSI devices...
amiboot -k kernel 53c7xx=validids:0x3F
this allows only device ID's 0,1,2,3,4 and 5 for linux to handle.
(this is a bitmasked field - i.e. each bit represents a SCSI ID)
These commands work on a per controller basis and use the option 'next' to
move to the next controller in the system.
amiboot -k kernel 53c7xx=nodisconnect:0,next,nosync:0
this uses No Disconnection on the first controller and Asynchronous
SCSI on the second controller.
Known Issues:
Two devices are known not to function with the default settings of using
synchronous SCSI. These are the Archive Viper 150 Tape Drive and the
SyQuest SQ555 removeable hard drive. When using these devices on a controller
use the 'nosync:0' option.
Please try these options and post any problems/successes to me.
