|If the sound adapter is built into the mboard, the correct sound software and associated software download is on the ECS web site in the downloads for your specific mboard model, if it's a retail mboard model.|
If it's a OEM only mboard model - made only for brand name systems builders and there is no retail model that is the same on the ECS web site - then you need to get the correct sound software download from the brand name system's web site in the downloads for the specific brand name system model.
You must load the main chipset drivers for the mboard.
Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.
