如何在Linux操作系统下查看有关PC卡(pcmcia)的信息？
您可以使用以下命令：

• pccardctlPCMCIA卡控制实用程序
• lspcmcia显示扩展的PCMCIA调试信息

输入以下命令：

# pccardctl ls

或者

# lspcmcia

输出示例：

Socket 0 Bridge:   	[yenta_cardbus] 	(bus ID: 0000:03:01.0)

要查看插槽0的当前状态，请执行：

# pccardctl status 0

输出示例：

no card

要获取有关套接字0的更多信息：

# pccardctl info 0

语法如下：

pccardctl command socket

其中，命令可以是以下任意一项：

status
           Display the current socket status flags.

       config
           Display the socket configuration, including power settings, interrupt and  I/O  window
           settings, and configuration registers.  --not yet implemented

       ident
           Display  card  identification  information,  including product identification strings,
           manufacturer ID codes, and function ID codes.  Not yet implemented for cardbus  cards.
           Use lspci instead.

       info
           Much  like  the ident command, but its output is formatted as a series of Bourne-stype
           shell variable definitions for use in scripts.  Not yet implemented for cardbus cards.

       ls  Display extended debugging information about the PCMCIA sockets and devices present in
           the system.

       suspend
           Shut down and then disable power for a socket.

       resume
           Restore power to a socket, and re-configure for use.

       eject
           Notify all client drivers that this card will be ejected, then cut power to the
           socket.

       insert
           Notify all client drivers that this card has just been inserted.
