Here are the instructions.
Download the newest Vortex2 drivers into a file on your hard drive, you can name the file Vortex2. These can be found at
http://www.vortexofsound.com/drivers/drivers.htm Vortex 2 (AU8830 reference) Windows 95/98 (ME uses the 9x kernel as well).
Unzip the file you downloaded into the new folder you created.
Locate and open the file called au30mmed.inf in that folder. Remove the semi-colon in front of the "HKR,Config,DisableBusDetection,1,1" line in the [AspenOverides.Addreg] section:. The correction should then look like this:
[AspenOverides.Addreg]
; virtual devices
;HKR,Config,DisableJoystick,1,1
;HKR,Config,DisableMPU401,1,1
HKR,Config,DisableDOSModemPort,1,1
HKR,Config,DisableSBFM,1,1
HKR,Config,DisableRealModeLegacySBFM,1,1
HKR,Config,DisableRealModeLegacySBFMUsingREM,1,1
HKR,Config,DisableSBFMIRQLevel,1,1
HKR,Config,DisableSBFMIRQSharing,1,1
HKR,Config,DisableBusDetection,1,1 <--------------------That is the line to edit!!!! NO Semi-colon!!
; a3d
;HKR,Config,EnableA3DReserve,1,1
;HKR,Config,NumHost3DBuffers,1,6
HKR,Config,Reserve2DSRC,1,8
close out and when prompted to save the changes say yes and you are all done.
Remove the card from device manager. Restart your computer and get into Bios. In Bios set the “PNP OS” option to “NO” so that the card is configured before Windows starts. Also in bios, get to PCI EXCLUSIONS and exclude IRQ 5 from the resource table. Save your bios settings and exit setup.
When windows starts it will detect the card and ask fro the driver disk. Direct it to the new file you have just created. DO NOT insert your original driver disk! If promted to insert the Windows CD, do so.
Your card is now set up, but the IRQ for Soundblaster emulation may be shared with something it shouldn’t be, usually your parallel port. Go into your C drive through My Computer, right click on the Autoexec.bat file, scroll down and click on EDIT.
The line should read “SET BLASTER = A240 I5 D1 T4”. The I5 is the IRQ for Soundblaster emulation. Since you have IRQ5 reserved in bios, it is not being used for any other devices. This line in Autoexec enables SB emulation, so make sure it is set to 5 as above. If you had to change it, save the changes and reboot to get this setting.
