	Fixed timing race condition with removable media (lost IORequest if
the timing is just wrong).

	When removable media does a not-ready to ready transition, assume
insertion even if no insertion error code is returned.  (Fixes initial
insertion on drives like the Toshiba 3301.)

	Make sure changes to sync negotiation are flushed to memory when
doing a renegotiate if a target is too slow.

	Unknown command error is now IOERR_NOCMD instead of -1.

	Avoids sending Mode Sense commands to WORM devices (locks up the
Pioneer CDROM-writer).  Might cause problems with other worms...

	Never attempts to use vectored interrupts, since there's a bug in
the hardware.

	Should work under V37 in an A3000.
