14.3.21. Kernel Configuration for PCMCIA
- Question:
- Which kernel configuration options are relevant to support PCMCIA cards under Linux?
- Answer:
- The following kernel configuration options are required to support
miscellaneous PCMCIA card types with Linux and the PCMCIA CS package:
- PCMCIA IDE cards (CF and true-IDE)
To support the IDE CardService client, the kernel has to be configured with general ATA IDE support. The MPC8xx IDE support (CONFIG_BLK_DEV_MPC8XX_IDE
flag) must be turned off. - PCMCIA modem cards
The kernel has to be configured with standard serial port support (CONFIG_SERIAL
flag). After the kernel bootup the following preparation is needed:bash# mknod /dev/ttySp0 c 240 64
This creates a new special device for the modem card; please note that/dev/ttyS0 ... S4 and TTY_MAJOR 4 are already used by the standard 8xx UART driver)./dev/ttySp0 becomes available for use as soon as the CardServices detect and initialize the PCMCIA modem card. - PCMCIA Wireless LAN cards
Enable the "Network device support" --> "Wireless LAN (non-hamradio)" --> "Wireless LAN (non-hamradio)" option in the kernel configuration (CONFIG_NET_RADIO
flag).
- PCMCIA IDE cards (CF and true-IDE)
