Writing and reading via the RF interface requires a portable hand held reader or door reader. Software residing in the hand held reader and portal gate controller are required to support the RF interface. Access to the EAI area data from the system side is provided by the DMI browser provided with the software. When data is written to the EIA through the SMBus it is done either dynamically or statically and depends on the data. Dynamic update of some of the data is done either by the system BIOS or by the AssetCare software each time it is loaded by obtaining the information directly from the device or operating system. Other types of information must by entered and updated by a system administrator or other authorized person. All data entered into the EAI area must be associated with one of the device types defined in Figure 22. Although every device entered must use one of the device types defined, the inclusion of a specific entity in the EAI area is optional. However, to get maximum utility from the EAI hardware, the data should be as complete and accurate as possible. Chapter 6. IBM System Management Tools 33
