Disk Boot Failure on IBM Intellistation M 6850

I have an IBM Intellistation M Pro 6850 that was running fine and then suddenly showed "Disk Boot Failure" Insert sytem disk. I have powered it down and back up but it will not boot, Duh!. My question is Can this be a bad power supply? I have another, similar age machine exactly the same and went through a lot of money to determine that the Power supply had gone bad. The machine was not doing exactly the same before it crashed but I remember that it would not boot.
These power supplies are hard to find. Of course, IBM couldn't put just a generic PS in the workstation they have a special connector pin.

Thanks,
Pooyie

 

Sounds like your boot drive has failed or the OS is corrupt.
