70 Appendix BCMOS Central Management: Extracting CMOS Settings to the File Serverfor DistributionCAUTION: It is recommended to initially complete these procedures on a file serverdesignated to test the success of your CMOS central management settings/process.While the central configuration method can be used to enforce your CMOS settings ina production environment, be aware that any thin client that logs into the file serverthat contains the cmos.ini and its extract and restore commands will be subject tothose commands (CMOS overwrites).CMOS central management allows ThinOS administrators to easily manage CMOSsettings for large deployments of thin clients using central configurationmethodologies. This case example uses C10 BIOS version 1.0B_SPC001-0407. However,you can use these instructions for other supported BIOS versions.Step 1: Prepare a Reference Device containing BIOS version 1.0B_SPC001-0407 or later1. On the thin client you want to use as a Reference Device (the reference device willbe the golden image you will use to distribute to other thin clients), enter the BIOSSetup Utility (during boot, press and hold the Delete key, enter the passwordFireport—this is case sensitive—and press Enter) and configure the CMOS settingsyou want (supported CMOS settings include: AutoPower, BootOrder, P-key setting,BiosPassword—and for C10 BIOS version 1.0B_SPC001-0407 or later theWakeOnLAN setting).2. Save your CMOS settings before exiting the utility.3. Shut down the thin client.Step 2: Prepare a File Server containing a CMOS INI File1. On your file server, create a cmos.ini file and place it in the wnos directory/folderunder the file server ini directory (be sure the wnos directory on the file server hasupload privilege).2. In the cmos.ini file, write the following line:Device=cmos Action=extractStep 3: Reboot the Reference Device to the File Server containing the CMOS INI File1. On the thin client you want to use as a Reference Device, start the thin client.2. In the Login dialog box, enter the credentials you need to access the cmos.ini file.3. After login, you can open the event log (System Information icon > SystemInformation dialog box > Event Log tab) to view a CMOS: extract toC10_cmos.1.0B_SPC001 event. This means that the CMOS central management file(containing the CMOS settings from your Reference Device) is now copied to thewnos directory/folder on the file server. As this is a C10 BIOS version1.0B_SPC001-0407 example, the CMOS central management file name would beC10_cmos.1.0B_SPC001. These CMOS settings are now ready for distribution toother thin clients.Step 4: Prepare the File Server containing the CMOS INI File for Distribution1. On your file server that contains the cmos.ini file for distribution, write the followingline in the cmos.ini file:Device=cmos Action=restore2. Save the file.
