57.Pp 58.Cd "# hp300" 59.Cd "isa* at isabr?" 60.Sh DESCRIPTION 61The system includes a machine-independent ISA bus subsystem 62and several machine-independent ISA device drivers. 63.Pp 64Attachments are machine-dependent and depend on the bus topology and 65ISA bus interface of the system. 66Drivers able to use DMA attach at 67.Nm isadma ; 68otherwise they attach at 69.Nm isa . 70.Pp 71Note that interrupt mappings on the i386 may require that the BIOS 72be configured to reserve the interrupts for these devices as "Legacy ISA". 73If such configuration is not done, the system may use those interrupts 74for 75.Xr pci 4 76or 77.Xr isapnp 4 78devices instead. 79.Pp 80.Ox 81provides support for the following devices. 82Note that not all architectures support all devices. 83.Ss SCSI
