First, I wouldn't install windows to the SATA drives. The install becomes unstable, especially the boot sector. If you still want to install windows to the SATA drives and have them as the C: drive, there are a couple of options. You hit on the first which is to remove the other drives, temporarily. The other option is to use an interesting Windows Bug. If you enter the bios, and go to the Standard BIOS Options menu, and set the hard drives to NONE. Important, do NOT disable the Onboard IDE connectors from the Integrated Peripherials. Reboot the comptuer and boot the Windows XP CD, press F6 to load the SATA Drivers. When the setup menu boots, it will still display the IDE drives. Partition the SATA Drive, and ignore the fact that that it might not be the C: drive. Then Reboot the computer. After you boot Windows CD with the SATA Drivers again, the SATA Drive will be the C: Drive. This is due to the fact that Windows will scan for BIOS drives, and load those drives after the "SCSI" Drivers.
