Installing the UltraSound Extreme into a PC running Windows NT v4.0
- Make sure that NT is running reliably on your computer.
- Shut down your computer and install the Ultrasound Extreme into an empty ISA slot on your motherboard; restart your computer.
- Once the computer is up and NT is running, insert the NT CD-ROM; close the AutoPlay menu if it opens.
- To install the drivers for the Extreme, select START/SETTINGS/CONTROL PANELS and double-click on the MULTIMEDIA icon.
- Select the DEVICES tab.
- Double-click on AUDIO DEVICES and make sure no devices of this class are already installed; if one exists it must be removed before continuing. Once you've checked this, "OK" the screen away.
- Select ADD and choose UNLISTED OR UPDATED DRIVER.
- Browse the NT CD; start at the root level and go to DRVLIB\AUDIO\ESS\i386; click on OK; verify the path is correct and click OK; check that the driver listed is ESS688\ESS1688\ESS1788 AudioDrive; click on OK.
- The "ESS Base I/O Address" and the "ES16(7)88 Configuration" settings (IRQ, DMA, MPU401) can be accepted or changed at your discretion; make changes if desired and click on CONTINUE to go to the next option. Note that the ADVANCED tab will allow you to adjust the DMA buffer size if needed.
- When finished click on OK, then select RESTART NOW. Once your PC has rebooted into NT you should have audio; if not, work on the assumption that the drivers are installed and working and investigate other areas of audio failure such as speaker connection, Volume Control settings, etc.
