Are you running the latest chipset drivers?

If not, install the Intel Software Chipset Utility, then the Ultra ATA Storage Driver, and last ... the Intel Application Accelerator.
Reboot between each driver installation.
I know that your drives are not ATA/100 ... but the Application Accelerator won't install on the system unless it detects the Ultra ATA Storage Driver.
