Centos 4.0 on SC440 SATA

[eclark]

Assuming the SC440 is the sata controller in the 2950s, Dells official 
response was "we are in the business of making hardware, not being concerned 
with actual support". The SATA module for this latest and most bleeding edge 
is megaraid_sas, which only exists in very recent versions of the 26 kernel. 
There are backported patches for it in 24, but these are _Very Specific_ to 
the linux distros Dell supports. Those can be found on their website, and 
include suse9 and rhes3/4. Specifically, the following:

  megaraid_sas-v00.00.03.01-RHEL30-GA-i686-all.tgz
megaraid_sas-v00.00.03.01-RHEL30-U3-i686-all.tgz

megaraid_sas-v00.00.03.01-RHEL40-U3-x86_64-all.tgz
megaraid_sas-v00.00.03.01-SLES9-SP1-i686-all.tgz
megaraid_sas-v00.00.03.01-SLES9-SP1-x86_64-all.tgz

megaraid_sas-v00.00.03.01-SLES9-SP2-x86_64-all.tgz
megaraid_sas-v00.00.03.01-SLES9-SP3-i686-all.tgz
megaraid_sas-v00.00.03.01-SLES9-SP3-x86_64-all.tgz

Be aware that none of these patches are portable. Any one of them requires 
massive rewriting of the module. There is a guy on the list however who has a 
rh72 backport of the module, but it also isnt mainline pluggable, and 
requires some modification to work. If you need any sort of extensive testing 
on your kernel before pushing it into production and do not run any of the 
three distros above or a 26 kernel, you are SOL.
