This one from NewEgg: SNT SNT-SATA1842B 4 x 2.5" HDD in 1 x 5.25" bay SAS / SATA 2.5" Hot Swap Backplane RAID cage http://www.newegg.com/Product/Product.aspx?Item=N82E16817993017 It takes up a single 5.25" bay, has a 4-pin molex power connector, and holds 4 2.5" SATA drives, with front panel access. I have two Seagate 180GB (ST9160827AS) drives (RAID1) and a Hitachi 120GB (HTS54161) drive (backup disk). The 4th bay is presently empty. (my Motherboard is this: ASRock K10N78 AM2+/AM2 NVIDIA GeForce 8200 ATX AMD Motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E16813157159 I have a Semperon 1-core processor and 2gig of RAM. ) Just set the BIOS to 'AHCI' mode, added irqpoll to the kernel params (needed to get the kernel to properly talk to the controller), and it just works, both CentOS 4.8 (32-bit [inherited from my previous PIII system]) and CentOS 5.x (64-bit xen). > > - KB > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- Get the Deepwoods Software FireFox Toolbar!
