I just upgraded my Dell XPS 410 system. I have been using the onboard RAID controller, but just configured two new 1Tb drives as a RAID1. The system runs through the Dell bios, and loads the SATA AHCI bios. The screen displays all of the SATA devices, and then hangs for a couple of minutes. It then displays the RAID volume and included devices. Then it loads Win7x64. Everything is working fine. Is there anything I can do to speed up the boot process? Can I disable the AHCI in the system bios? I have the Intel storage manager loaded in Windows7, and it works as designed. Will it stop working if I disable the AHCI in the bios? What to do?
