AMPLIFIER TIER SETTING UPDATES ============================== Purpose of updates: ------------------- In order for the Bose Sound system on your computer to work properly, the BIOS setting for the Amplifier card must match the card which is actually installed in the machine. NOTE: The setting will match unless the system board has been replaced. Warnings: * This update CANNOT be run from within Windows. Running this update from within Windows, will SEVERELY damage the system BIOS and require the system board to be replaced. * Care must be taken to make certain that the BIOS setting matches the actual Amplifier card installed. The sound system will not function properly with incorrect setting. How to apply: 1) Determine the type of Amplifier installed: * Look at the back of the computer, where the purple speaker connector from the monitor is plugged in. * If there is ONE (1) purple connector, then the Amplifier is a "TIER-1" type card. * If there are TWO (2) connectors, one purple and one pink (for the base module), then the card is a "TIER-2". 2) Determine the system BIOS setting for the card: * Download "CKTIER.EXE" from the Aptiva E-Support website. * Run the CKTIER program either by double-clicking the icon for CKTIER.EXE where you just downloaded to, or by typing CKTIER.EXE at a command prompt. * If the type of card installed, matches the type listed in step (2) above, NO ACTION IS NEEDED. 3) If you do NOT have a model 2116(MM55) or 2128 (MM75) monitor connected to the system, you MUST set the BIOS to a "TIER-0" setting. To do this, reboot from the Diagnostic & Utility CD and press "0" (Zero) to exit the menu. At the DOS prompt, run ' G:\DISK\CRYSTAL\CLYDE\RCAND15\INSTALL\DISK0\TIER0.BAT'. NOTE: These systems were designed for use with the MM55 and MM75 monitors ONLY. Using a different monitor with this system will cause various sound and functionality problems. 4) If the type of card installed DOES NOT MATCH the type listed in step (2) above, then you must run the appropriate update to correct the error. 5) If you have a "TIER-1" type card installed, reboot from the Diagnostic & Utility CD and press "0" (Zero) to exit the menu. At the DOS prompt, run: 'G:\DISK\CRYSTAL\CLYDE\RCAND15\INSTALL\DISK0\TIER1.BAT' 6) If you have a "TIER-2" type card installed, reboot from the Diagnostic & Utility CD and press "0" (Zero) to exit the menu. At the DOS prompt, run: 'G:\DISK\CRYSTAL\CLYDE\RCAND15\INSTALL\DISK0\TIER2.BAT' 7) Restart the computer and repeat step #2 to make certain the setting now matches the card type installed.
