TP General - OS/2 ESS Audio Address does not change after Initialize
Applicable to: World-Wide
This document only applies to systems that have the ESS Audio chip.
SYMPTOM:
The IO Port address for the ESS Audio Chip does not change at the Thinkpad Utility screen under OS/2 after CMOS Initialized
CONFIGURATION:
Any ThinkPad using the ESS audio device running OS/2 Warp.
SOLUTION:
To reset Audio I/O setting to 220, just initializing CMOS is not sufficient. This is due to Audio driver's design. The ESS driver does not get I/O address value from CMOS directly but uses the parameter in CONFIG.SYS.
ex.) ES1688DD.SYS /B:240 /D:1 /I:5 /M330,5 /N:ES16881 $
The Thinkpad Utility in OS/2 displays this CONFIG.SYS setting because audio driver actually uses this value. Of course, if some value is selected in utility it sets the value to both CMOS and CONFIG.SYS.
When you want to reset Audio setting, as a first step, initialize CMOS, then as a second step modify the CONFIG.SYS statement shown above.
1)Initialize CMOS <-- CMOS is reset to 220
2)Open Audio advenced dialog
3)Press OK <-- CMOS and CONFIG.SYS is updated
4)Reboot
To set Audio address to 240,
1)Open Audio advanced dialog
2)Select 240 I/O and press OK
