Missing sound driver

Has anyone came across a sound driver for a Intel 810 mobo? I have a different identical system also running NT that states its sound card is a Crystal Audio Codec but I can’t find the drivers used to install this integrated option.
The systems are identical Gateway’s, but Gateway has been no help to me and neither has the Intel site. Intel states that the sound option is a SB and I’ve tried to install it, but each time I’ve tried, it hung the system. I’ve even tried DriverGuide but couldn’t find anything. ANY and all help will be appreciated.
