I am testing a CT2800. This one has an IDE connector. (I've seen other models marked CT2800 without the IDE interface.)
I run diagnose.exe in pure DOS, everything works. I install the card inside Windows 98, everything works.
However, if I run a DOS game in pure DOS, I get problems. There seems to be a DMA conflict somewhere. I suspect it's to do with onboard IDE. I cannot find a jumper on the sound card to disable the IDE. I was hoping to find a jumper labelled IDEEN, which does appear on the CT2801, whose purpose is to disable the IDE port.
I am now thinking - perhaps I need to run a software utility, to disable the IDE "in EEPROM mode?", so that I then don't run in to any DMA conflicts with my DOS games.
Any clues please? I know there's one or two CT2800 users out there, I can see you! 😉
Thanks! 😀
