What soundcard do I have?

I am attempting to re-install W98 on a Hitachi Deskview all-in-one PC. I know that the PC has some kind of ESS Audio chip in it but I don’t know what version. Hitachi tech support said the PC was a custom job built for a private company and they don’t have any records on it. (That’s how I got it. The private company distributed them to doctors for internet access then proceeded to go belly-up. I bought the orphan from a doctor friend who can’t use it.)

Any software out there that can tell me what specific sound chip is in this thing?
