To my knowledge, no software reads the SET GALAXY statement (except perhaps for some proprietary Aztech software). The first 3 parameters will be the same as your SET BLASTER statement. K10 is your Windows Sound System (WSS) IRQ and P530 is your WSS base port. All 16-bit Sound Galaxy sound cards …

To be honest, I'm not 100% sure, but I would assume it must be routing the MIDI data via some non standard port/address. The original Sound Blaster MIDI port specifications should be available (since this card most likely will follow that specification). However, since it's MIDI port is not MPU-401 …

Most games that supports MIDI (whether MT-32 or General MIDI), only works with the original Roland MPU-401 standard. Some older games expects a real mode MPU-401 MIDI interface, wheras all General MIDI compatible games will work with a UART mode MPU-401 MIDI interface. In the early days of sound …

I agree with dr_st 's recommendation.

vinegar + water is my preferred method as well , I wouldn't go 100% vinegar though - but that depends on how "strong" it is.

You can try to run Doom from within a Windows 3.11 command prompt. It should utilise the Windows drivers, but I've only tested this myself on a Windows 98SE installation. Otherwise, just download the updated patch for Doom (I have a suspicion that you still have version 1.2). That is probably the …

Earlier versions of Doom didn't have native AWE support. It was introduced with a later release, namely version 1.4. Just …

For AWE based sound cards, applications and games are expected to use the EMU8000 chip directly (via the default port of 620h). However, for games that didn't support the EMU8000 synthesis chip natively, Creative wrote a tsr called AWEUTIL. AWEUTIL uses Non Maskable Interrups (NMI's) to "catch" I/O …

Another thing that comes to mind is whether you're using the older 40 wire or later 80 wire ribbon cables. These drives will undoubtedly make use of the older type, but I think it most likely relates to the fact that these drives don't make use of the more modern transfer speeds (as already mention …

Try disabling the onboard IDE interface of the card and see whether the problem disappears. Chances are that you're not going to use it.

Your configuration appears to be correct. The key is to ensure that "set midi=synth:2". The rest you can leave with their default settings. 1 routes your MIDI data to the internal EMU8000 synthesizer, whereas 2 routes it to the external MIDI/joystick port. The Aweutil /em command is to enable MIDI …
