This chip isnt bad at all. I do have a Vectra VEi8 HP MITAC OEM board as well. It should work with the drivers I have attached below. It will also install a TSR for Soundblaster compatibility in the autoexec.bat (cw*audio.com).
In addition to that I have also added an additional Crystal Soundfont
additional Crystal SoundFont (This can be installed after the driver below, and iirc gives you an additional soundbank as well as the ways and means to switch them)
The attachment wko2z1en.zip is no longer available
The driver for W9x (This should be installed first)
The attachment wko1x1en.zip is no longer available
You only have a single option in the BIOS iirc, and that is to enable/disable the integrated audio.
