Previously a4091.device would only report a generic sense error when there's a disk detected but the disk is not done spinning up. This made it hard to properly handle the slow/fast spinup DIP switch of the A4091. This change detects ASC = 0x04 / ASCQ = 0x01 and reports it as "ERROR_NOT_READY".

|
* the following:
|
|
* XS_NOERROR, // 0 there is no error, (sense is invalid)
|
|
* XS_SENSE, // 1 Check the returned sense for the error
|
|
* XS_SHORTSENSE, // 2 Check the ATAPI sense for the error
|
|
* XS_DRIVER_STUFFUP, // 3 Driver failed to perform operation
|
|
* XS_RESOURCE_SHORTAGE, // 4 adapter resource shortage
|
|
* XS_SELTIMEOUT, // 5 The device timed out.. turned off?
|
|
* XS_TIMEOUT, // 6 The Timeout reported was caught by SW
|
|
* XS_BUSY, // 7 The device busy, try again later?
|
|
* XS_RESET, // 8 bus was reset; possible retry command
|
|
* XS_REQUEUE // 9 requeue this command
|
|
* The above should be modified to use values compatible with AmigaOS
|

* DoIO() error codes.
