|That system appears to be at least 10 yrs old. I can't imagine that it will run XP very well unless you have at least 512MB RAM & a *real* video card (not onboard graphics).|
According to IBM/Lenovo, the audio chip is the ESS Solo-1 but there were many different versions. You should open the case & find the exact audio chip model number...for example ES1869.
Did you check to see if there's a generic XP driver that you can use? If the card isn't auto-detected, will will have to force it by going to Control Panel > Add Hardware.
- Let the Wizard run, then select "yes, I have connected the hardware" & click Next
- Scroll to the very bottom & select "Add a new hardware device", then click Next
- Select "Install manually from list", then click Next
- Select "Show all devices", then click Next
- On the left side, scroll down & select ESS Technology, then scroll down the right side to see if your audio chip is listed. If it is, select it & click Next.
If it's not listed, you're gonna have to do some googling to see if you can find a compatible driver. If you can't find an XP driver, a Win2000 driver *should* work.
