Retro Sound – Diamond Technology DT0398

Last Updated on 13 April 2026 by Suffocation

Herausgekommen um 1998 mit PCI Schnittstelle , kommt diese Karte eher gewöhnlich daher. Sie besitzt einen Forte Media FM801 Soundchip. Für diesen gibt es sogar noch einen DOS Treiber mal schauen ob er auch mit diese Karte funktioniert.

Driver

I found the drivers with the Vogons:

Vogonen – Driver Download

Archive.org - Driver CD

Win 9x/NT/2000/Dos

fm801-nov2000Download

Two

Use the Install.exe from the package above. The settings will be queried and the driver and configuration will be stored on C:. A corresponding entry will be made in the Autoexec.bat. I have moved the files to a driver directory on my system. The path of your own machine must be adjusted accordingly.

The card works well for me in DOS, I tested it with Monkey Island 1, Doom I and Duke Nukem 3D. The test machine was a Pentium I 200 MMX with a 2MB ATI MACH 4 graphics card.

ACHTUNG das Installationskript ist nicht ganz Fehlerfrei es ändert „goto %CONFIG%“ in „goto CONFIG“

Sound problems

Windows no sound in DOS mode

  • Install/start DOS driver
  • Install SB16 Emulation

No music

  • Check settings, is the address correct?

No TFX sound

  • Check settings, SIMM, Address, IRQ, DMA...

IRQ Busy

  • BIOS IRQ Search Reset
  • Assign IRQ in BIOS
  • Use another slot (usually means another IRQ too)
  • Reserve IRQ for ISA (it will then not be available for PCI)

IRQ nicht für Dos geeignet

  • Reserve IRQ for ISA (it will then not be available for PCI)
  • See IRQ Occupied

Choppy sound with interruptions

This can happen if the IRQ is doubly assigned. For this, please look at the solutions for „IRQ Occupied“.
