Reconfiguring Hardware with kudzu When you add or
Reconfiguring Hardware with kudzu When you add or remove hardware from your computer and reboot Red Hat Linux, a window appears during the reboot process advising that hardware has either been added or removed and asking if you want to reconfigure it. The program that detects and reconfigures your hardware is called kudzu. The kudzu program is a hardware autodetection and configuration tool that runs automatically at boot time. If you like, you can also start kudzu while Red Hat Linux is running. In either case, here is what kudzu does: 1. It checks the hardware connected to your computer. 2. It compares the hardware it finds to the database of hardware information stored in the /etc/sysconfig/hwconf file. 3. It prompts you to change your system configuration, based on new or removed hardware that was detected. The following is a list of hardware that kudzu can detect (according to the kudzu README file), followed by a description of what kudzu does to configure the device. Other devices may be detected as well (such as USB devices). Network devices Adds an Ethernet interface alias (eth0, eth1, etc.) if necessary and either migrates the old device configuration or creates a new one. SCSI Adds an alias for scsi_hostadapter. Video card Runs the Xconfigurator command to configure the video card. Sound card Runs the sndconfig command to configure and test the sound card. Mouse Links the new mouse device to /dev/mouse and runs the mouseconfig command to configure and test the mouse. Modem Links the new modem device to /dev/modem. CD-ROM Links the CD-ROM device to /dev/cdrom. Scanner Links the new scanner device to /dev/scanner. Keyboard Runs the kbdconfig command to reconfigure the keyboard. Also, if you are using a serial console, it makes sure /etc/inittab and /etc/securetty are configured to be used by a serial console.
