many games readme's will come with sample config.sys files dependinging on what type of memory the need

remember run memaker.exe if you have it

Some games may need the soundcard to emulate a Sound Blaster if they don't recognize the Yamaha.

I think the yamaha does emulate a soundblaster

Yes indeed, check out Yamaha's legacy driver support including DOS mode:

CLICKY!!!

It's a YMF719, which is a rebranded YMF715, which is described as
"Controller+Codec, SB/SBPro/SB16/MPU-401 compatible, PnP, IDE, Integr. OPL3, adds power management and 3D sound."

Right now I'm having problems with it, though, as it is making sound via OPL3 in Windows, but non-MIDI sound will not play. I've had this problem since I installed the wrong drivers and uninstalled them. I'm going to try a reinstall of the default Windows drivers.

It may need a TSR for the sounds to work properly, like my old SB32 PnP did.

Filipetolhuizen was right. I fixed my problem (sound card was loose and dusty), installed the W98 driver pack (which included the TSR for DOS), and now my sound works. Also, Davros' suggested CONFIG.SYS and AUTOEXEC.BAT settings work great. Thank you so much.

Now all I need are game recommendations. I've already installed Strike Commander, Jazz Jackrabbit, Tyrian 2000, Epic Pinball, and Zone 66.

Celeron 300, anything around the level of unreal should run ok, look for games released 1999 or earlier
as for dos games doom, descent, duke3d, wing commander, system shock, crusader, syndicate, beneath a steel sky (free at gog http://www.gog.com/en/gamecard/beneath_a_steel_sky)

that should keep you going for a bit
