I have to admit that it was new to me that liion cells tend to leak, too. Haven't had any issues with them on mainboards so far. But for some reason, in these modules or seems to be not uncommon. Have checked my modules as well. Most were ok but the one in my Roland RA50 was start leaking, too. ( …

OptI 930 has integrated opl3 clone (OptiFM). You are probably thinking of the 931 model. Most OPTi 930 cards that I've come across use 1:1 OPL3 copies, which sound identical to the real thing. Additional info can be found here: http://www.os2museum.com/wp/opl3-copies/ Assuming that website is …

A Pentium class Socket 7 system will do fine. Every late DOS game will run fine on it. Every early and speed sensitive dos game will also work using setmul and/or slow down the system using an old isa vga card and/or underclocking the cpu. Other pros are: PnP Bios so easy setup of pnp isa soundcards …

OptI 930 has integrated opl3 clone (OptiFM). But some cards with Dream wavetable also use the Dream FM-emulation (Terratec Maestro 32/96 as an example). You then will notice it because Dream-FM sounds different to opl3. The Dream 9233 is a solid wavetable with good rolandish sound, nothing wrong …

If external cache is enabled but the system instable, try to add 1 waitstates at cache read cycle waitstates (and write as well). This can help if you have slow cache modules. Also try CLK2/4 for 8mhz ISA Bus Speed. Everything above that might overclock anything ISA related which also can lead to …

I would recommend a non-pnp / jumper controlled card for a 486 system. So the ES688 (dedicated OPL3) or ES1688 (ESFM) would be good choice if available. Why shouldn't I use PnP on mobo with PnP capable BIOS? If you have a pnp bios, pnp card is fine. ES1868f is fenerally good quality, easy setup and …

Yes - For me I prefere VXD drivers over WDM in case of legacy support. (I think of ALS4000 or ESS Solo-1 but I'm pretty sure this belongs to others as well) So If DOS gaming in Windows 9x is important for you, choose older VXD drivers instead.
