+comment "Bus Support"
+
+config DIO
+ bool "DIO bus support"
+ depends on HP300
+ default y
+ help
+ Say Y here to enable support for the "DIO" expansion bus used in
+ HP300 machines. If you are using such a system you almost certainly
+ want this.
+
+config NUBUS
+ bool
+ depends on MAC
+ default y
+
+config ZORRO
+ bool "Amiga Zorro (AutoConfig) bus support"
+ depends on AMIGA
+ help
+ This enables support for the Zorro bus in the Amiga. If you have
+ expansion cards in your Amiga that conform to the Amiga
+ AutoConfig(tm) specification, say Y, otherwise N. Note that even
+ expansion cards that do not fit in the Zorro slots but fit in e.g.
+ the CPU slot may fall in this category, so you have to say Y to let
+ Linux use these.
+
+config AMIGA_PCMCIA
+ bool "Amiga 1200/600 PCMCIA support"
+ depends on AMIGA
+ help
+ Include support in the kernel for pcmcia on Amiga 1200 and Amiga
+ 600. If you intend to use pcmcia cards say Y; otherwise say N.
+
+config ISA
+ bool
+ depends on Q40 || AMIGA_PCMCIA
+ default y
+ help
+ Find out whether you have ISA slots on your motherboard. ISA is the
+ name of a bus system, i.e. the way the CPU talks to the other stuff
+ inside your box. Other bus systems are PCI, EISA, MicroChannel
+ (MCA) or VESA. ISA is an older system, now being displaced by PCI;
+ newer boards don't support it. If you have ISA, say Y, otherwise N.
+
+config ATARI_ROM_ISA
+ bool "Atari ROM port ISA adapter support"
+ depends on ATARI
+ help
+ This option enables support for the ROM port ISA adapter used to
+ operate ISA cards on Atari. Only 8 bit cards are supported, and
+ no interrupt lines are connected.
+ The only driver currently using this adapter is the EtherNEC
+ driver for RTL8019AS based NE2000 compatible network cards.
