166CHAPTER 6Analyzing HardwareSummaryThis chapter was all about hardware. It described how to list the devices detected by RedHat Enterprise Linux with lspci and lsusb, detect hardware with Kudzu and ddcprobe,retrieve information from the BIOS, and list the currently configured and loaded kernelmodules. It also provided information about the recently developed Hardware AbstractionLayer (HAL).Without hardware, a computer system could not exist. But, without an operating systemsuch as Red Hat Enterprise Linux to interact with the hardware and allow the hardware tointeract with each other, the hardware would be useless.
