Hey guys,
I honestly need some help understanding IRQ's and resource conflicts.
I have an old Toshiba 440CDT Laptop. After some blood, sweat and tears upgrading to the latest bios (it has no floppy drive, just CD-ROM). She works great now ....except for the audio.
So let me explain... I initially wanted to run Win98 SE, but when it came to sound... every time i booted up into windows, it would lock up. I tried several different drivers, IRQ settings in BIOS, but no luck. Safe Mode actually worked fine however, because there were no sound drivers loaded I'm guessing?
So I reformatted for the 20 billionth time, and now I'm having better luck with Windows 95 OSR2.5.
When i first install windows 95, everything works fine.. hell it even has sound! but in device manager, there's no mention of Yamaha OPL3 at all. Just "generic sound synth, MPU-401, and Windows Sound system". So at this point, the sound works fine with the stock windows drivers, however, there's exclamation marks next to almost everything under sound, and no mention of Yamaha OPL3.
So I start installing the latest Yamaha Win95 drivers from Toshiba's website, and things do work AT FIRST. After installing the drivers, I now have the proper devices installed it seems, listed as "SB Pro", "Windows Sound System", and "Yamaha OPL3-SAx Sound System"... and ALL sounds are working great. CD-Audio plays, Windows wave sounds, it's all PERFECT...
BUT....when you click the details in the device manager, Almost every sound device has SEVERAL resource conflicts between them. Once I start playing with IRQ's, DMA access, and I/O addresses, things start going to shit. I'm now at the point where sound doesn't work at all, so I'm reloading Win95 OSR2 once again from scratch. 😲
