This is not correct. Kernel 2.4.5-ac13 and later have a driver to support the Fasttrak raid system. I wish Promise was more helpful during the development of this driver, as it is currently developed fully independent and without any help / support or even acknowledgement of Promise. As a result, not yet all RAID modes and configurations are fully supported. Greetings, Arjan van de Ven
