controller found on many old world Apple Power Macintosh systems and
clones.
Machines supported by the mesh driver include:
- Power Macintosh 7600, 8500, 9500 and 9600.
DEVICE FLAGS
The mesh driver supports the following flags.
Bits 0-7: Disable disconnect/reselect for the corresponding SCSI ID
number.
Bits 8-15: Disable synchronous negotiation for the corresponding
SCSI ID number.
Disconnect/reselect should be enabled for tape devices, or SCSI bus
performance may be degraded.
