[SOLVED] I came across this link: [URL] goes to the necessary instructions to create a MS-DOS LIVE CD (I couldn't even managed it may exists). Following the tutorial I was able to update my machine! 
Hi everybody, I'm desperately trying to get a grip on how to change the firmware of my PowerEdge SC1425 server from A02 to A03.The official documentation speaks about a "FLOPPY" disk or an executable file. I find the floppy option quite ridiculous nowadays but I can't get to install this update even with Freedos! How did you managed it? Best regards. 
SC1425 bios A02 -> A03
