SCSI Host Adapter Detection

I have this problem. During the installation of Mandrake 8.0, it could not detect my AVA-1502 adapter on my system. So after the installation, I have to use 'modprobe aha152x aha152x=0x140,10,7," to have it detected. So now, in order to use my CDRW connected to the SCSI adapter, I have to issue the 'modprobe' command as root.
Need help to config my system so that it will automatic activate the SCSI card and CDRW during bootup. Which file should I edit and what to add? Please help. Thanks

add about the same thing to

/etc/modules.conf

look at the way it is done in there, and you will figure it out pretty quick
