Hi, I have a external SCSI DISK ARRAY, and I have installed RH9 at the PC with LSI SCSI now. I want to install Adaptec SCSI(ASC-29160) driver more. And then this SCSI DISK ARRAY can boot from PC with ASC-29160 at once, if the LSI SCSI is broken down. The /etc/modules.conf now is: alias eth0 e1000 alias eth1 e1000 alias scsi_hostadapter mptbase alias scsi_hostadapter1 mptscsih alias usb-controller usb-ohci How should I do and then the SCSI DISK ARRAY can boot from LSI SCSI or ASC-29160? regards, Longming 3/8
