I am not sure if this chipset is supported, we support the YMF754, the
B version is just a variant. Try going into the systems BIOS and turning
OFF plug and play aware OS and see if that helps. What version of the OS
are you running?
Thanks

Hi E.
Thanks,yes,that’s the problem,after I change the BIOS setting,everything
gets ok,thank you a lot.but can you tell me,as to an OS,what’s the different
mean between the non-pnp and pnp in the bios?
