If you have the cd then you have the documentation and the drivers for linux. However there are Red Hat drivers on the website but I did not see any source packages for it.The controller can run under MS-DOS or any DOS-compatible operating system using the standard AT BIOS INT 13h hard disk drive interface. To use the controller with other operating systems, you must install software drivers. Driver files for supported operating systems are available on the Universal Driver Suite CD that accompanied your MegaRAID controller.
You might have to look again or try somewhere else.
You might be able to change the RPM to another compatible format but this is not going to be to easy nor is it guaranteed to work.
Any one else ?
