AIX uses the configuration manager to configure devices, however, if the device does not exist, it will never be configured. You can install additional device software by running "cfgmgr" and tell it where the additional device software is located. On an AIX installation CD, the device software is located in the following directory:
/usr/sys/inst.images
Below is an illustration for installing a 100 MB Ethernet card:
If you purchase a 100 MB Ethernet card after installing AIX, and you knew the device software for the Ethernet card is on the AIX installation CD in the /usr/sys/inst.images, run this command to automatically install the device software.
1. Create a CD-ROM file system with /mnt as the mount directory: "smitty cdrfs" will take you to the correct menu
2. Place the AIX installation CD in the CD-ROM drive and type "mount /dev/cd0"
3. Type "cfgmgr -i /mnt/usr/sys/inst.images", or if you want to see what cfgmgr is doing.type "cfgmgr -vi /mnt/usr/sys/inst.images"
When cfgmgr polls the bus where the 100 MB Ethernet card resides, and was able to correctly identify it, cfgmgr will attempt to install the correct driver through an installp installation.
