If you guys are interesting on the new folder structure under \DrvDsk, you could reference the article Microsoft announce for Server2003 http://www.microsoft.com/whdc/device/storage/F6dirs.mspx It says about the Server2003 will load txtsetup.oem from proper subfolder as first priority instead of root directory, as the \i386, \amd64 or \ia64 folders is present. The benifits of it is to help user not to see many driver items in F6 installation. By following the new instruction, the RAID driver could be placed at different folders for different processor architectures. But the previous OS, including XP, can't recognize the fixed folder name. So, Windows NT4, 2000 and XP will parse the txtsetup.oem at root.That's why XP and previous OS still see 3 items as well. Only Server2003 will search txtsetup form the i386 and amd64 subfolders. If the boot CD is amd64 platform (SRV2003SP1 or XP-x64), it should only parse the txtsetup.oem from \amd64 subfolder and only one item is shown up. In the readme file, it also says that user should copy all files under DrvDisk folder. The driver disk VIA ComboRAID 4.30C provides should be the first fully compatible with the new driver disk structure I never saw.
