Configuring and Using Virtual Media

Overview

The Virtual Media feature provides the managed system with a virtual floppy diskette drive and a virtual CD drive, which can use standard media from anywhere on the network. (Figure 7-1 shows the overall architecture of virtual media.) With this feature, administrators can remotely boot their managed systems, install applications, update drivers, or even install new operating systems remotely from the virtual CD/floppy diskette drives.
