Please, where can I find updated drivers for A50M Hudson M1 chipset with Windows Server 2008 R2? I mean chipset drivers  (SATA and so), not only graphic drivers.

Motherboard: ASRock E350M1/USB3

I tried 12-8_vista_win7_win8_32-64_sb.exe downloaded from AMD Chipset Driver page but it works in Windows 7 and not in Windows Server 2008 R2

Thank You

I have never had a problem installing the AMD drivers for Windows 7 on Server 2008R2.  But they are hard to find on AMD's site, aren't they.

What I have been doing is select AMD 9-Series Chipsets, and Windows 7 - 64 bit.  This gives me http://support.amd.com/us/gpudownload/windows/Pages/raid_windows.aspx#2.  Yes, it is the same sb driver as yours.

I just (re)installed the driver from the 12.8 package.  It was at .\Packages\Drivers\SBDrv\hseries\AHCI\W764A in the expanded package.  I am using Windows Server 2008 R2 SP1 on an Asus  E35M1-M-Pro, with an E-350 CPU and the A50 Hudson M1 chipset.

Note, If your BIOS is like mine, it does not support RAID.  There is no RAID option for the onchip SATA channel, only IDE and AHCI.  So I have to resort to software, Disk Manager in Windows Server.  I have a 2.7 TB RAID 5 on four, 1 TB SATA III drives.  Each drive also has a 512 MB EFI partition and a 32 GB partition for a boot mirror.

Two: HD 4550, Phenom II x6 1090T on MSI 870A-G54, 16 GB DDR3 1333
Two: Asrock E350M1, 8 GB DDR3 1333
HD 5570, Athlon II X4 630 on Gigabyte GA-870A-UD3, 16 GB DDR3 1333
Dual HD 4650's in CrossfireX, on MSI RD 480 Neo2, 4GB DDR2 800.

Thank You,  bnborg.

Your answer is what I needed.

Yes, ASRock motherboard, like Asus one,  has no RAID support. I suppose it's chipset fault. I'm building a NAS where storage size is more important than speed or redundancy, so I don't need the array feature.
