Linux下即插即用设备的安装
Linux下即插即用设备的安装,Linux下即插即用设备的安装
现在,大多数发行套件中都有isapnptools。如果你的套件中有,安装它即可。如果你的发行套件中没有它,到http://www.roestock.demon.co.uk/isapnptools/ 去下载一份,解压后把isapnp 和 pnpdump 拷贝到目录 /sbin中即可。
下面就是实战阶段了。需要准备的就是把你所有要装的即插即用设备全部装好,以ROOT身份登陆。然后运行以下命令/sbin/pnpdump /etc/isapnp.conf,这会把你机器上所有的即插即用设备信息写入文件/etc/isapnp.conf中,下面是我的机器上的/etc/isapnp.conf文件的一部分:

我的系统中共有三个即插即用设备,分别是NE2000兼容网卡,Yamaha OPL~SA2声卡和一个USR 56K modem。由于文件太长,我略去了声卡和modem部分。
接下来就是为每个设备分配所需资源。有许多方法可以实现。第一种,也是最简单的方法就是,如果你在同一台机器上也装了WIN95或WIN98,通过控制面板的系统的属性页,可以看到在WINDOWS系统下各即插即用设备的资源,记下用到Linux即可。如果你的机器中没有其它的操作系统,采用第二种方法。即手动分配资源,只要各设备资源不发生冲突就行。手动分配资源以前,最好先看一下已经使用的中断列表、I/O列列表,它们分别位于/proc/interrupts、/proc/ioports、/proc/dma。一旦你确定了各设备使用的资源,就可以分配了。
选择分配给每个设备的资源非常简单。你只要去掉你的设备所需资源前的注释号即可。描述资源的行很容易找到,因为它们总是以INT, IO或 DMA开头。在这些行之前是
