Install Windows on a Computer with ICH9R RAID

This solves the problem where the Windows installation will say “Cannot find IAstor.sys” during the file copy process (but sees the hard drive partitions initially). 
 If you already made a floppy with drivers using utility: 
 1. Create folder $ OEM $ on a floppy with drivers. 
 2. Create folder TEXTMODE in folder $ OEM $, so structure will look like $ OEM $\ TEXTMODE 
 3. Copy files (not move, but copy!) 
 
 iaahci.cat 	 iaahci.inf 	 iastor.cat 	 iastor.inf 	 iastor.sys 	 txtsetup.oem 
 
 to the folder TEXTMODE . 
 Now Windows Setup will find all files fine.
