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!)
to the folder TEXTMODE.
Now Windows Setup will find all files fine.
