but was wondering if I could use my Soundblaster 2 (which has the CMS chips in it) for GameBlaster sound at the same time?

The PSU I will be using won't have a -5v rail. I know this causes issues when using the SB2.0 for soundblaster sound, but does it also cause issues when using CMS sound?

I'd expect lack of -5V to be a problem for you. A lot of early sound card pre-amps like a double ended supply.

Aside from the -5V issue: certainly.

Just be sure to set them on different resources. The SB2.0 with CMS is from a time when more titles required default settings, so I'd do the most compatible ones there and fit the AWE32 around it:

SB2.0:
A220 I7 D1 T3
AEW32:
A240 I5 D3 (or 0) T6 H5 (or 6 or whatever) P330 E620

Is true the Sb 2.0 dont likes fast cpu as P1MMX?

I know that some SB Pro routines don’t like fast CPU’s, even on a SB16. Sometimes you need to disable the L1 cache to get it to work. Also some OPL3 software doesn’t like fast CPU’s.

You absolutely need -5V for CMS on an SB 2.0. There are adapter cables that can generate it when going from ATX to AT, but I can't find anything on ATX to ATX. It is a very simple circuit with an LM 7905 Voltage Regulator, so if you really want to do it this way, you could make one yourself.

CPU speed will likely also be an issue with the card.

old ATX supplies with -5 aren't exactly hard to find...

What about 388h ?
Which of the cards is going to handle that?

Both, actually. When a program writes to 388h (OPL2/OPL3), they will both output FM Music simultaneously regardless of other settings, as long as there aren't any other conflicts. Freaking laptop keyboard.
