Dell CS24-SC BIOS & BMC v2.5 Firmware Download


Here are the most current BIOS and BMC firmwares available for the Dell CS24-SC that I know of. The BMC upgrade makes the fans considerably less loud and has a few upgrades to the BMC Software/Web GUI. With the Bios update I am now able to run Windows Server 2012 and Windows 8.1 on the bare hardware and I can confirm that they do now support 2TB+ drives, sort of. I have 4 of these, all updated the same – 1 supports SAS, 2 support 2TB+ drives and 1 does not. Note I haven’t tested 2TB support on the one that supports SAS.

Note: There is always the risk of bricking a device when flashing firmwares, please use this software at your own risk! I accept no responsibility for any damages caused by using/flashing this software!
