I think I have just made the worst mistake one can made - please help me recovering from it.
A guy from another room came over said to me this is a BIOS update (or something similar) for the new servers we just bought. Would you mind making an image and
dd into the floppy so I can use it for the server installation.
I was in such pressure doing 5 things in parallel so I said okay, and he pointed out to the IBM readme file.
I simply followed the instructions there and did the mounting and the
dd line. As a result, rebooting the machine few minutes later brought up boot failure error message.
I started the machine with the ubuntu live cdrom and noticed that during new installation attempts, when it gets to the partitioning part, no hard-drive is presented.
Is there a safe way rolling back this stupid action?
