### SYNOPSIS

mesh* at obio? flags 0xffff scsibus* at mesh?

### DESCRIPTION

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 .

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)
