Recently I found out that iDrac has security issues here and according dell is not supposed to be connected to internet.
I'm trying to upgrade it's firmware so I downloaded bootable iso from https://dell.app.box.com/v/BootableR610/folder/32719590128.
I checked the md5 which is correct. I used dd command to put the iso to the usb disk but it would not boot. I tried BIOS and UEFI. Now I have no idea how to proceed.
