If you want just ATA/SATA support of single drives, that will work. The RAID functionality will never work, because it is 100% software-based (the 16-bit BIOS setup is just for boot-time). I call this "FRAID" and it is not hardware RAID (it adds *0* hardware). Any drivers will be proprietary and not open source, because they contain RAID code licensed from a 3rd party that is not GPL (and never will be, because it is the core IP of that 3rd party and the lifeblood of their business). There are independent, clean room GPL drivers (ataraid + pdcraid), but they are likely to corrupt your volume -- especially on newer FRAID BIOSes that may change the organization. -----Original Message----- From: Bogdan Nicolescu <bo2k2 at yahoo.com> Sent: May 18, 2005 3:31 PM To: CentOS mailing list <centos at centos.org> Subject: [CentOS] Installing CentOS on RAID PATA not SATA - A8V I'm trying to install CentOS 4 on an A8V on the PATA/Raid drives on the Promise controller. The Promise controller is recognized (sata_promise), but the PATA drives are not recognized. Base on this thread https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=147303 it seems that there is a patch which was merged in 2.6.11 to get pata working. Any ideas how to proceed?
