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 tar- get 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/rese- lect or performance will suffer.
