# DESCRIPTION

The `esp` driver provides support for the NCR 53C90, 53C94 and 53C96; Emulex ESP100, ESP100A, ESP200 and ESP406; and Qlogic FAS216 and FAS408 SCSI controller chips found in a wide variety of systems and peripheral boards. This includes the Qlogic ISA and VLB SCSI host adapters, and the Sun Fast SCSI buffered Ethernet for Sbus (FSBE/S, X1053A, Sun part # 501-2015).

For Qlogic PCI SCSI host adapters, use the isp(4) device.

# CONFIGURATION

The `esp` driver supports the following flags for use in config(1) files:

bits 0-7:
  disable disconnect/reselect for the corresponding SCSI target
bits 8-15:
  disable synchronous negotiation for the corresponding SCSI target
bits 16-23:
  disable tagged queuing for the corresponding SCSI target

"Target" is synonymous with SCSI ID number.

Note that SCSI tape drives should be allowed to perform disconnect/reselect or performance will suffer.
