The first problem is, that the SRCZCR isn't supported on the SE7520BD2. See http://www.intel.com/support/motherboards/server/se7520bd2/sb/cs-013538.htm - it's the SRCZCRX.
Once you have the right RAID card, then you can try the drivers at http://downloadcenter.intel.com/Product_Filter.aspx?ProductID=1766
Thanks for the reply , I have the right card it's SRCZCRX indeed, but the drivers seem not to work for me.
Well at least i have a floppy drive and can istall with F6. I think my problem is with the RAID setup.
Could someone give me advice please what should be done to configure these SCSI drives (BIOS settings + SRCZCRX settings)
I am really frustrated with this box now ... please prevent any HW damages due to frustration
In the BIOS, you have to have the zero-channel Option ROM enabled, I think. You've already gone through Ctrl-G and used the Configuration Wizard to create the array, right?
I realise this post is old and hopefully it still gets posted, however I'm having problems upgrading the mirrored drives from Maxtor Atlas 10K 74Gb to Seagate 15K 147Gb drives. The drives aren't being detected in the RAID bios (ctrl G).
I've searched everywhere, but can't find information about compatibility issues. Are you able to shed some light?
Edit: Disregard the above. I noticed on another post someone was successful updating to a 146Gb HDD
No worries. I found http://www.intel.com/support/motherboards/server/sb/CS-020501.htm and http://support.intel.com/support/motherboards/server/se7520bd2/sb/CS-013538.htm . What's the link you found for the 146Gb?
The link for the 146Gb drives was on this forum, and after looking through the HDD docs that came with the drives, it turns out the problem was my lack of SCSI knowledge (didn't realise they had jumpers).
I still had problems after cloning, where the onboard RAID couldn't find the boot/host (I think) on the new drives, so ended up installing them on a spare PERC 320 controller, no problems.
Thanks for the link.
I remember when I began to use the SRCZCR with Windows 2003. I didn´t have problems with the drivers and the Operating System recognized without problems the hard drives (I used a normal floppy unit conected to the mobo).
But during the installation of the Operating system, I remember the process stopped when remain 34 minutes, more or less. Those problem was solved updating the firmware of the RAID controller.

Sorry I have not finished the last message
The SRCZCRX, which is the right zero channel RAID CARD for the mobo SE7520BD2, works perfectly with 2003.
Recently I was repairing an old server and I installed Windows 2003 R2 SP2 with the SRCZCRX without problems.
I downloaded from
the last firmware version and the last driver. Of course, I used a floppy unit which was plugged to the mobo, no a USB unit, because Windows 2003 only works with two or three brands of USB floppy units (TEAC, MITSUMI,...)
I hope it can be useful
Thanks for the heads up. Didn't try updating the firmware, and that probably would have fixed the problem. Did end up placing both drives on an old Perc 320 controller, which did the job.
