I solved the issue by passing /forcetype to the DOS upgrade program. My issue seems to be the same as this one. Thanks again for your suggestions.
I have an EMC Avamar ADS Gen3 3.3TB, internally a Dell PowerEdge R710. I am attempting to update the BIOS firmware from version 6.0.7 to 6.4.0, but I have encountered several issues. My management OS is OpenSuSE Leap 42.3. Running succeeded. My first problem is that srvadmin-all is missing from that repository and Zypper can't find it. I then ran dsu. It succeeded to upgrade all of the firmware in my server's inventory except the BIOS itself. When the upgrade failed, it showed an error message: I then tried to produce a bootable ISO from dsu. The ISO was indeed saved; I wrote it out to a USB disk using dd; but then when I attempt to boot from the USB disk the BIOS says that no operating system is found, regardless of whether I attempt hard disk emulation or floppy emulation. Are there any workarounds I can use to get the BIOS updated? And how can I install srvadmin-all? Thank you.
