I found what I was looking for: a Sound Blaster Live! value. CT4780. Even has drivers for Win98SE! And also, I don't need the RAM anymore - - I don't trust 98SE with more than 1 GB, even though it is patched. 1 GB runs Lubuntu fine. I run 98SE for my old games and Windows applications. I use Lubuntu for internet capability - - XP will run, and rather well at that - - but it doesn't have a lot of life left, and with a GeForce2 MX Windows 7 is out of the question.
Well 98SE was short-lived. I liked its raw speed, but XP is infinitely more useful.
In any case, I'd like the extra RAM but it's no requirement. Also, it can be PC2700 as well - DDR-333 that is (I've always been a little lysdexic regarding translating different notations). I figured out that it runs it at 333 anyway.
