If you only work under WIN95/98, it is not necessary to switch off the PnP-OS. Only under DOS you need it, because else you get an errormessage from the EWSINIT (this do you need for the DOS-Initialization).

No, you don't need special drivers.

Please read the article in the Master Class section about this.

In short: the VXD contains all the functions of the EWS synthesizer and the DRV is the interface between the VXD, the operating system and the hardware.

If you are using a motherboard with the BX chipset you cannot use IRQ 9 for ISA cards and thus the EWS64. Assign a different available IRQ to the synthesizer.

I have upgraded to a newer driver version but the firmware is still the old one.

The EWSINIT initialization program is loading an old firmware version from the EWS64 directory under DOS. To update this file simply copy the EWS64_OS.BIN file from your Windows directory to your EWS64
directory.

You can solve this problem by renaming the RMM.PDR file in the \Windows\System\IOSUBSYS subdirectory to RMM.BAK. You can use Windows Explorer to do this. The Windows Protection Fault will generally no longer occur.

It is possible that REMOVE64.EXE did not completely delete all entries, meaning that there were errors
during the installation.

The best thing to do now is the following:

• In the AUTOEXEC.BAT file delete the line containing EWSINIT.EXE.
• Delete the entire EWS64S directory. (Remember to back-up your personal mixer settings first)
• Now open Windows Explorer. There is an option called 'View' on the menu. Click this option and
  select 'Options'.
• Enable the 'Show all files' option if it was disabled. Press OK to confirm.
• Now double-click your Windows directory. You will see all the subdirectories, one of which is called INF.
• If there is a subdirectory called 'Other' in the INF directory, skip step a)
  
  a) In the INF directory there are files that begin with OEM (oem0..., oem1..., oem2..., etc.). Delete these files.
  b) In the OTHER directory you will find a file called TerraTecEWS64.INF. Delete this file.
• Now start the REMOVE64.EXE program (in the Driver\Remove directory) from your 2.x driver CD.
• When you reboot Windows 95/98, a new installation of the drivers will be offered to you because the
  system does not recognize the sound card anymore. Follow the instructions which will then be displayed.
• Then start the Setup program in your APPLICATIONS directory.

The EWS64 resources may not be modified in the Device Manager. The resources can be modified using the EWSMIXER.EXE program under DOS (not a DOS window). This program can also be started directly from the EWS64 ControlPanel. Just select the 'SETUP' button.
Take note of free and reserved resources (IRQs, DMA channels and I/O ports) before making any changes.
