First off Welcome to the forums
The drivers for the iHAS324-98 B is included in Windows 7 no need to install drivers
unless you are talking about drivers for a add on SATA PCI / PCIE card then you will
need to install the drivers for the card for it to work correctly.
Could it be the motherboard chip-set drivers you are asking about we need a little bit
more info to be able to help you out.
