57.Pp 58.Cd "# hp300" 59.Cd "isa* at isabr?" 60.Pp 61.Cd "# loongson" 62.Cd "isa* at glxpcib?" 63.Sh DESCRIPTION 64The system includes a machine-independent ISA bus subsystem 65and several machine-independent ISA device drivers. 66.Pp 67Attachments are machine-dependent and depend on the bus topology and 68ISA bus interface of the system. 69Drivers able to use DMA attach at 70.Nm isadma ; 71otherwise they attach at 72.Nm isa . 73.Pp 74Note that interrupt mappings on the i386 may require that the BIOS 75be configured to reserve the interrupts for these devices as "Legacy ISA". 76If such configuration is not done, the system may use those interrupts 77for 78.Xr pci 4 79or 80.Xr isapnp 4 81devices instead. 82.Pp 83.Ox 84provides support for the following devices. 85Note that not
