SATA, PATA and SCSI Play Nice

I am planning on building a storage server for a Kiosk Manufacturer that wants to use it to update their kiosks.

They are planning on using an Intel Desktop board (I know, I tried to get them to use a Server Board). So here is the configuration

Intel 865PERL Motherboard

512 Meg RAM

Pentiun IV 2.8 GHz Prescott

Here is the storage they provided me

IBM 9 Gig SCSI

4 - Western Digital 250 Gig PATA, 7200 RPM, 8 Meg Cache

2 - Seagate 400 Gig SATA, 7200 RPM, NCQ Drives

The question is, how should I configure it? The SCSI drive has to be the D: Drive, as it is used for mission critical applications. So that cannot be the boot drive. My thoughs are as follows

C: - Boot Drive Primary Master

D: - SCSI

E: - Secondary Master

F: - Primary Slave

G: - Secondary Slave

H: - SATA-0

I: - SATA-1

I don't think I can get the SATA drives to boot in this configuration, so I am going to go with PATA as the boot drives.

Anyone with experience using this motherboard and SATA drives? I am just concerned that the SATA will conflict with the SCSI if I set it to boot.
