Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

README for WarpEngine/A4000T/A4091 SCSI kernels.
|
|
|
|
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.
|
|
|
|
e.g.
|
|
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.
