mesh —
Apple Macintosh Enhanced SCSI Hardware driver
mesh* at obio? flags 0xffff
scsibus* at mesh?
The mesh driver provides support for the SCSI host
  adapters found on most supported models with on-board SCSI. The Apple Network
  Server models use the esp(4) and
  esiop(4) devices for SCSI, not
  mesh.
Models supported by mesh are:
  - Apple PowerBook (2400, 3400, G3, and G3 Series)
- Apple PowerBook (G3 Series (bronze keyboard))
- Apple Power Macintosh/Performa (4400, 54xx, 5500, 6300/160, 6360, 6400,
      and 6500)
- Apple Power Macintosh (7300, 7500, 7600, 8500, 8600, 9500, and 9600)
- Apple Workgroup Server 8550
- Apple Power Macintosh G3 (Beige G3)
- APS Tech (M*Power 604e/200)
- Motorola StarMax (3000, 4000, 5000, and 5500)
- Power Computing (PowerBase, PowerCenter, PowerCenter Pro, PowerCurve,
      PowerTower, PowerTower Pro, and PowerWave)
- UMAX (Apus 2000, Apus 3000, C500, and C600)
- UMAX (J700, S900)
Some models have a separate SCSI bus dedicated to external devices
    using the esp(4) device. On
    these systems, the mesh SCSI bus is operated in SCSI
    ‘Fast’ mode (10 MB/s) and the external
    esp(4) bus is operated at 5
    MB/s. This applies only to the following models:
  - Apple Power Macintosh (7300, 7500, 7600, 8500, 8600, 9500, and 9600)
- Power Computing (PowerCenter, PowerCenter Pro, PowerCurve, PowerTower,
      PowerTower Pro, and PowerWave)
