SATA driver problem

Recommended by Wim's BIOS...

I am trying to install SATA WD 160gb hard drive on ASUS P4S800D-X motherboard.
When installing Windows i get a messaage"set up did not find any hard disk drives installed in your computer".
When i plug both my SATA and IDE drives it reads IDE as promary,cant locate the SATA drive at start up window.
When I loaded Windows off IDE drive to format the SATA 160gb drive and has someting like 149GB,i can download files onto it but will not start up when booting up computer.
Tryed running programs to install the drive but nothing worked for me. No longer have the motherboard CD. Searched web all over and didnt find the right answer for me. Tryed F6 + floppy+software at Windows instalation and didnt fix my problem. What can I do to finally have the SATA drive installed on my computer?

Do this with the IDE harddisk NOT installed and see if you can get that to work. If you can it is a matter of chaning the boot prioroty in the bios making the SATA controller the first boot controller.

the size of 149GB is btw. correct for a 160GB hdd because the manufacturers use 2^30 (binary) to calculate a GB and all others use 10^9 (decimal) for GB (like 1kg is 1000g, not 1024g). thus a simple factor can be used to determine the 'real' GB size of a drive...f = 10^9/2^30 ~= 0.9313
real size would be: real size=f*advertised size

okay, back to your problem: windows needs drivers to use the onboard sata controller. they can be injected directly into the windows install cd (tricky) or you can load them from disk during the install with the F6-key option.
download the drivers here, decompress them on your harddisk, go into the floppyimage dir, go into the dir that fits your southbridge chip (that would be '964_180' in your case i assume) and copy the contents on an empty disk. just connect a cd-rom, your sata hdd and a floppy, boot windows install from the cd, hit F6 and place the disk into the drive. the drivers get loaded automagically and you can continue to install windows. be sure to set the hdd in the bios as boot drive afterwards!
