I've got Gigabyte 8-IRXP mobo with two 60GB maxtor HDDs in mirror I started the installation process of rh7.3 with the "expert" option, and I was prompted to insert driver disk. That's ok, because i've got one ;-). http://tw.giga-byte.com/support/d_other.htm#promise276 After install everything was fine. RAID0 with DMA. And my /boot is also there, because I dont have other drive to boot from ;-) I am 90% sure that this driver should work for other brands, not only Gigabyte. Worth trying. And all this on the 2.4.18-3 kernel which ships with rh7.3 The problem is when upgrade to newer kernel. I don't know how to make it load the modules for RAID. The driver itself has instalation script, but this means that you must have a running box, booted from other drive. So if someone knows how to add the working modules from the old kernel to the new one, let me know thanks
