On another machine, I already had performance problems with SATA controllers in IDE emulation mode (recognized as piixide), which disapeared when selecting AHCI mode in the BIOS (turning it to be recognized as ahcisata) I will report on this as soon as the server will be idle enough to be rebooted. -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz [email protected]
