Introduction to EISA bus machine-independent drivers and
  support
options EISAVERBOSE
Machine-dependent; depends on the bus topology and EISA bus
    interface of your system. Typical EISA buses are either connected directly
    to the main system bus, or via an PCI to EISA bridge. See the
    intro(4) documentation for your
    system for details.
NetBSD includes a machine-independent EISA bus subsystem
  and several machine-independent EISA device drivers.
Your system may support additional EISA devices. Drivers for EISA
    devices not listed here are machine-dependent. Consult your system's
    intro(4) for additional
    information.
NetBSD includes machine-independent EISA drivers, sorted
  by device type and driver name:
  - cac(4)
- Compaq array controllers.
- mlx(4)
- Mylex DAC960 and DEC SWXCR RAID controllers.
 
  - ahb(4)
- Adaptec 174x SCSI interfaces.
- ahc(4)
- Adaptec AIC 7770, 274x, and 284x SCSI interfaces.
- bha(4)
- BusLogic BT-74x SCSI interfaces.
- dpt(4)
- DPT SmartCache/SmartRAID III and IV SCSI interfaces.
- uha(4)
- Ultrastor 24f SCSI interfaces.
 
  - ep(4)
- 3Com 3c579 and 3c592 10Mbit Ethernet, and 3c597 10/100Mbit Ethernet
      interfaces.
- le(4)
- Digital DE422 Ethernet interfaces.
- tlp(4)
- Digital DE425 Ethernet interfaces.
 
Note that most or all EISA devices also have PCI or ISA
    equivalents. These are listed in
    pci(4),
    isa(4), or
    isapnp(4), respectively. The
    manual pages for each individual driver also lists the supported bus
    variants.
The machine-independent EISA subsystem appeared in NetBSD
  1.2.
