1. Installation Instructions
----------------------------
* Install from Setup Package
1. Run Setup.exe from the extracted Setup Package
   or run self-extract execution Audio_{Version}_Multi.exe
   to start Setup process.
2. In 98/ME, Setup program will prompt you to reboot system.
   After system reboot, driver installation will complete properly.
   In 2000/XP, driver installation may complete without any system reboot.

* Install from Device Manager
1. Start Control Panel's System applet, then
   select "Device Manager" tab (in 98/ME),
   or select "Hardware" tab and click on "Device Manager" button (in 2000/XP).

(If audio driver has never been installed ...)
2. In the device list,
   double click on the "PCI Multimedia Audio Device" item
   under "Other Devices" category.
3. In the Properties dialog,
   click on "Reinstall" button.

(If audio driver has already been installed ...)
2. In the device list,
   double click on the "ALi Audio Accelerator WDM Driver" item
   under "Sound, video and game controllers" category.
3. In the Properties dialog,
   select "Driver" tab and click on "Update Driver" button.

4. Follow Hardware Update Wizard (or Update Device Driver Wizard) prompt.
   Select Install from the specific location and specify the correct path.

------------------------------
2. Uninstallation Instructions
------------------------------
* Uninstall from Add/Remove Programs
(This method is recommended if driver is previously installed by Setup program.)
1. Start Add/Remove Programs from Control Panel.
2. Select "ALi Audio Accelerator WDM Driver" item.
3. Click on "Remove" button.

* Uninstall from Device Manager
1. Start Device Manager from Control Panel's System applet.
2. Right click on "ALi Audio Accelerator WDM Driver" item, then
   select "Remove" (or "Uninstall") item from the popup menu.

--------------------------
3. ALi Sound Setup Utility
--------------------------
* From Control Panel window, double chick on the "ALi Sound Setup" applet
  icon to launch this program.

* MIDI Configuration
- Click on the "Sample" tab.
- "Sample Set" and "Sample Rate": select to determine a wavetable for ALi MIDI device.
- Press [OK] button and restart Windows to make these settings take effect
  on the next Windows session.
NOTES:
- These MIDI settings are meaningful only when system uses ALi Wavetable MIDI 
  device. To use ALi Wavetable MIDI device, execute Multimedia applet
  in Control Panel window, then from the MIDI tab, select "ALi Wavetable MIDI" 
  as the MIDI output device, in stead of "Microsoft GS Wavetable SW Synth".
- The alternative of Sample Set settings, 1MB, 4MB, or 8MB, represents the size of
  various ALi wavetable sample files. The larger wavetable sample file can provide
  better quality of MIDI sound, and consume more system resources (CPU computing
  and memory usage).
  Or user can select DLS option to use the GM.dls sample file provided by Microsoft.

* CODEC Power Saving Configuration
- "Power Management" tab
- "Enable Power Management" checkbox:
	to enable or disable CODEC power saving function
- "Always"/"Only in battery power mode" combobox:
	to select the active time of CODEC power saving function
- "Turn off CODEC power after (when no sound is played)" combobox:
	to set the idle time to automatically power down CODEC (PR0:ADC, PR1:DAC)
- "Enable External Amplifier Power Down":
	to further power down CODEC (PR2:Mixer, PR7:EAPD)
- [Apply] button: to apply the new settings,
- [OK] button: to apply the the new settings and exit program
