K9A2Gm V2 under W2k - SATA/IDE issues

Question

I am having trouble to get W2k running on the K9A2 GM V2 board (I would need that for sw-compatibility issues).
I got it installed and running by enabling IDE emulation. Problem is that the drive gives me 1.5 Mbit/s transfer rate. On another PC with SB600 in RAID-1 configuration same drives gives me 80MB/sec. I used the MSI F-6 x86 drivers that came with the mobo (ATIDrv/SBDrv/IDEATA133). BIOS tells me that the drive has UDMA-6 enabled. The driver is fine in the device manager and shows up as AMD PCI SATA/IDE Bus Driver. Version is 5.1.0.8.
-> Did anyone succeed to run W2K with acceptable disk performance?
I also tried a SATA/RAID setup (using a single drive RAID READY configuration). After the F6 drivers were loaded I got a message that the AHCI drive file is corrupted. I tried several drivers and floppy disks. I also changed the floppy drive with no other effect.
A bit confused I noted a bunch of other drivers on the MSI CD as JMicron, Promise and Silicon_image. I thought the drives work though the SB700 and thus only AMD drivers would make sense. Is that a misunderstanding?
I am running out of ideas. Any experiences or comments?
Thanks,

My system specs are:
    AMD Phenom 9950 Quad Core
    2GB Ram
    1x 500GB SATA HDD Hitachi HDP725050GLA360
    1x DVD Rom on IDE Primary Master
    ATI HD 3450 Graphics card, 512MB
    400W PSU
    1 additional TP-Link GB LAN card
    W2K Pro SP4
    BIOS A7302 AMS V2.1 021109
I also observed: in Device Manager mit DVD is listed with UDMA mode. The HDD however is not. The fields look like that:
  - type: "automatic detection" but its grayed out
  - mode "Use DMA if available"
  - actual mode "not accessible", or "not available" (its a translation, I dunno what the EN version displays)
That must be the reason that the thing is so slow, but why does it not use the UDMA mode?

What PIO bug?
There used to be a problem with Win2K, but that has nothing to do with the controller used, this was Win2K going wrong and that was fixed in SP1 or 2, forgot the exact one.
There fix should be in included in SP3 or SP4 (which i use). I saw couple of Microsoft posts how to deal with that. However, I found many postings in the web with the problem and very often the Microsoft fixed did not work too. I have been trying workarounds for a couple of days now. For some guys another driver did the job (e.g. some "SATA" driver, but I did not find a case with a SB700 chipset.)

However, when putting the controller in RAID is doesn't use the normal IDE way but it uses SCSI (mini-port) way.
There are no drivers for Win2K, so use IDE mode or XP, btw AHCI in XP is fairly unstable too but that's an XP problem.
But you only have 1 drive, so why bother with RAID or ACHI? IDE-mode is faster anyway.
I agree. RAID/AHCI would have been a workaround for the slow IDE only.

Set the controller in IDE mode and use the Microsoft drivers! as there are no specific Win2k drivers.
The slow IDE mode is the initial problem I described in the first post. With the MS drivers I could not get the HDD out of PIO mode. On the MSI driver disk I found specific AMD SB700 drivers for "SATA Controller (Native IDE mode)". The driver was 5.1.0.8 and is designated WinXP32, but usually the XP drivers work fine for W2K. I tried those as well as the standard MS drivers, but I could not get my HDD out of PIO mode.
