     The system	includes a machine-independent ISA bus subsystem and several
     machine-independent ISA device drivers.

     Attachments are machine-dependent and depend on the bus topology and ISA
     bus interface of the system.  Drivers able	to use DMA attach at isadma;
     otherwise they attach at isa.

     Note that interrupt mappings on the i386 may require that the BIOS	be
     configured	to reserve the interrupts for these devices as "Legacy ISA".
     If	such configuration is not done,	the system may use those interrupts
     for pci(4)	or isapnp(4) devices instead.

     OpenBSD provides support for the following	devices.  Note that not	all
     architectures support all devices.

   SCSI	controllers
	aic(4)	      Adaptec AIC-6260 and AIC-6360 SCSI interface

	wdc(4)	      Standard Western Digital type hard drive controllers:
		      MFM, RLL,	ESDI, and IDE/ATAPI.  See also the pciide(4)
		      device driver which is used instead on machines with PCI
		      IDE controllers.
