Where to find driver required during clean install

I'm trying to clean install Windows 8 Pro x64 under UEFI and RAID on a ASUS P8Z77-V Deluxe motherboard on a blank SSD. I'm installing from an OEM system builders DVD. I plan to create a RAID1 array later after successful installation of Windows.

For the installation I do the following:-

I'm using these BIOS settings:-

SATA Mode set to RAID
CSM set to Disable
Secure Boot set to Windows UEFI Mode

I press F8 and select the UEFI option on the DVD

The installation procedure then starts but after the screen where I enter the language, country etc I get a screen which says that SATA drivers cannot be found and that I should browse to their location.

I have downloaded all the drivers from the ASUS site for this board onto a USB pen drive. When I browse to this location the installation procedure says no drivers can be found there.

Please advise exactly which SATA drivers the installation procedure wants and where I can find them.

Many thanks for help.

I am not good on what you are trying to do, but check this tutorial out: SATA Driver - Load in Windows 8 Setup.

See if this helps: How to Install Windows 8 Using the "Unified Extensible Firmware Interface" (UEFI)

What type of file extension is the driver...is it zipped or in an extension that can't be read when installing from desired location. Is it the right bit type...that can play hell with it, looking for a bit type of 64 and whats on the thumb drive is 32 bit...it wont find it.

have a look at this one..
