DESCRIPTION
NetBSD provides machine-independent bus support and drivers for PCMCIA (Personal Computer Memory Card International Association) a.k.a. PC Card, CardBus devices.
HARDWARE
NetBSD includes the following machine-independent PCMCIA drivers, sorted by function and driver name: Serial interfaces and modems com 8250/16450/16550-compatible PCMCIA serial cards and modems. Network interfaces an Aironet 4500/4800 and Cisco 340 series 802.11 controller. awi 802.11 controller based on the AMD PCnetMobile chipset. cnw Netwave AirSurfer Wireless LAN interface. ep 3Com 3c589 EtherLink III Ethernet card. mbe Ethernet card based on the Fujitsu MB86960A/MB86965A chipset. mhzc Megahertz Ethernet/Modem combo cards ne NE2000 compatible cards. ray Raytheon Raylink and WebGear Aviator2.4 802.11 controller. sm Megahertz Ethernet card. wi Lucent WaveLAN/IEEE and PRISM-II based 802.11 controller. xi Xircom CreditCard Ethernet SCSI controllers aic Adaptec APA-1460 SCSI controller card. esp NCR 53C9x, Emulex ESP406, and Qlogic FAS408 SCSI con- trollers. spc Fujitsu MB87030/MB89352 SCSI controllers.

HISTORY
The pcmcia driver appeared in NetBSD 1.3.
BUGS
IO space conflicts NetBSD probes the PCMCIA IO bus width and uses that information to decide where to map PCMCIA IO space. For 10-bit wide cards, 0x300-0x3ff is used. For 12-bit wide cards, 0x400-0x4ff is used. Neither choice is perfect. In the 12-bit case, 0x400 appears to work in substantially more devices than 0x300. In the event that PCMCIA devices are mapped in 0x400-0x4ff and appear to be nonfunctional, remapping to 0x300-0x3ff may be appropriate; consult options PCIC_ISA_ALLOC_IOBASE and options PCIC_ISA_ALLOC_IOSIZE in options(4). Example: # Avoid PCMCIA bus space conflicts with the default IO space # allocation on 12-bit wide busses (base 0x300 size 0xff). options PCIC_ISA_ALLOC_IOBASE=0x300 options PCIC_ISA_ALLOC_IOSIZE=0x0ff Interrupt conflicts NetBSD attempts to probe for available interrupts to assign to PCMCIA devices. In some cases, it is not possible to detect all interrupts in use; in such cases, use of options PCIC_ISA_INTR_ALLOC_MASK may be neces- sary. See options(4). Unconfigured devices During autoconfiguration, if a message is displayed saying that your card is "not configured" it indicates that there isn't support for your card compiled into the kernel. To fix this problem, it may simply be a matter of adding the manufacturer and product IDs to the PCMCIA database or adding a front-end attachment to an existing driver. In the latter case, it is normally always necessary to get a dump of the CIS table from the card. You can do this by adding options PCMCIACISDEBUG and options PCMCIADEBUG into your kernel config file. Additionally, you will have to patch the kernel to enable run-time debugging. This can be done in the source by changing the variables pcmcia_debug and pcmciacis_debug to 0xff. Alternatively, you can patch the same variables at run-time using ddb(4). For most drivers you should also consider enabling any driver- specific debugging options. NetBSD 9.0 January 3, 2009 NetBSD 9.0
