cardbus, cardslot, cbb -- CardBus driver SYNOPSIS
cbb* at pci? dev? function ? cardslot* at cbb? cardbus* at cardslot? pcmcia* at cardslot? XX* at cardbus? function ? DESCRIPTION
NetBSD provides machine-independent bus support and drivers for CardBus devices. The cbb device represents the CardBus controller. Each controller has a number of slots, represented by the cardslot devices. A slot can have either a CardBus card or a PCMCIA card, which are attached with the cardbus or pcmcia devices, respectively. SUPPORTED DEVICES
NetBSD includes the following machine-independent CardBus drivers, sorted by function and driver name: Network interfaces ath Atheros 5210/5211/5212 802.11 atw ADMtek ADM8211 (802.11) ex 3Com 3c575TX and 3c575BTX fxp Intel i8255x ral Ralink Technology RT25x0 (802.11) rtk Realtek 8129/8139 rtw Realtek 8180L (802.11) tlp DECchip 21143 Serial interfaces com Modems and serial cards SCSI controllers adv AdvanSys 1200[A,B], 9xx[U,UA] ahc Adaptec ADP-1480 njs Workbit NinjaSCSI-32 USB controllers ehci Enhanced Host Controller (2.0) ohci Open Host Controller uhci Universal Host Controller IEEE1394 controllers fwohci OHCI controller Disk and tape controllers siisata Silicon Image SATA-II controllers. DIAGNOSTICS
cbb devices may not be properly handled by the system BIOS on i386-family systems. If, on an i386-family system, the cbb driver reports cbb0: NOT USED because of unconfigured interrupt then enabling options PCI_ADDR_FIXUP options PCI_BUS_FIXUP options PCI_INTR_FIXUP or (if ACPI is in use) options PCI_INTR_FIXUP_DISABLED in the kernel configuration might be of use.

The cardbus driver appeared in NetBSD 1.5. BUGS
Memory space conflicts NetBSD maps memory on Cardbus and PCMCIA cards in order to access the cards (including reading CIS tuples on PCMCIA cards) and access the devices using the RBUS abstraction. When the mapping does not work, PCMCIA cards are typically ignored on insert, and Cardbus cards are rec- ognized but nonfunctional. On i386, the kernel has a heuristic to choose a memory address for mapping, defaulting to 1 GB, but choosing 0.5 GB on machines with less than 192 MB RAM and 2 GB on machines with more than 1 GB of RAM. The intent is to use an address that is larger than available RAM, but low enough to work; some systems seem to have trouble with addresses requiring more than 20 address lines. On i386, the following kernel configuration line disables the heuristics and forces Cardbus memory space to be mapped at 512M; this value makes Card- bus support (including PCMCIA attachment under a cbb) work on some notebook models, including the IBM Thinkpad 600E (2645-4AU) and the Compaq ARMADA M700: options RBUS_MIN_START="0x20000000" BSD

isapnp -- introduction to ISA Plug-and-Play support SYNOPSIS
isapnp0 at isa? An isapnp bus can be configured for each supported ISA bus. DESCRIPTION
NetBSD provides machine-independent bus support and drivers for ISA Plug-and-Play (isapnp) autoconfiguration of PnP-compatible devices on an ISA bus. SUPPORTED DEVICES
NetBSD includes machine-independent ISAPNP drivers, sorted by function and driver name: SCSI interfaces aha Adaptec AHA-154[02] SCSI interfaces. aic Adaptec AHA-1520B SCSI interfaces. Disk controllers wdc Standard IDE and ATAPI drive controller. Serial and parallel interfaces com 8250/16450/16550-compatible ISA PnP serial cards and internal modems. Network interfaces an Aironet 4500/4800 and Cisco 340 series 802.11 interfaces. ep 3Com 3c509B EtherLink III Ethernet interface. le PCnet-PnP Ethernet interfaces based on the successor to the AMD LANCE chip. ne NE2000-compatible Ethernet interfaces. tr TROPIC based token ring interfaces. Sound cards ess ESS Technology derived PnP sound cards and devices. guspnp Gravis Ultrasound PnP sound cards. sb SoundBlaster, SoundBlaster 16, and SoundBlaster Pro sound cards. wss Windows Sound System compatible cards, e.g., most of the cards with Crystal Semiconductor chips. ym Yamaha OPL3-SAx sound cards. Miscellaneous devices pcic PCI PCMCIA controllers, including the Cirrus Logic GD6729. ISA Plug-and-Play devices also have alternate ISA drivers with static ISA IO address configuration. These are listed in isa(4). The isapnp bus ignores devices that have already been found and configured as isa(4) devices. The isapnp bus is only effective on machines which lack a PnP BIOS, or on which the PnP BIOS has been disabled. The manual pages for each individual isapnp driver also list the supported front-ends for other buses. SEE ALSO
