I tried everything but it hangs in the middle of the installation(RPMS) Redhat 6.2 & 7.1 Promise drivers are Bad!
They must be having problems with them. I just checked their website and this is posted on there Linux page: [08-31-01] The RedHat drivers have been temporarily removed. Please check back in a few days.
What is the exact model you have? I believe Roswell beta 2 (current beta for RH 7.2) includes drivers for more of the promise cards.
