Upgrading BIOS on IBM MCS-7835-I2 for Unity Platform Configuration CD

Unanswered Question
Mar 24th, 2010


I am trying to run the Unity Platform configuration CD on an MCS-7835-I2 server but cant get past the messsage below. The problem is that the solution is to upgrade the BOIS using 3.5" floppy. However the server does not have a 3.5" diskette drive.

Any ideas?



If you are using a server manufactured by IBM and the following message appears:

"The ServeRAID firmware and BIOS installed on your system must be upgraded or downgraded to be compatible with the RAID drivers on the Cisco Platform Configuration disc. For information on upgrading or downgrading, refer to the Cisco Technical Note Upgrading or Downgrading ServeRAID Firmware and BIOS on IBM Servers on Cisco.com."

do the procedures in the tech note RAID-Controller Firmware and RAID BIOS on IBM Servers Upgrade or Downgrade Procedure at http://www.cisco.com/en/US/products/ps6509/tsd_products_support_install_and_upgrade_technotes_list.html (the document title changed).

I have this problem too.

I just had to do this. I could find any other work around, but luckily had a usb floppy drive and

a couple disks. I think it actually downgraded the RAID. In the middle of the Wind 2003 install now. It successfully passed where the error hung me up.

I've seen this during upgrade of customer systems when they decide to use older hardware such as the I1 or I2 series

servers.  The solution that worked best (IMO) is to proceed with the Windows OS installation first (i.e., skip the Platform Configuration Disc) - if you have ordered an upgrade, you likely have a generic H1/H2 or I1/I2 disc that simply contains the OS.  Once you've installed the Windows OS, you can download the latest IBM drivers or use the disc that came with your system (if you still have it) to install the extra utiltiies including ServeRAID and etc.
