Cloned drive for a DOS system won't start.
I cloned a very old drive in anticipation of it failing. Well it failed.
1) The machine is a ROM-DOS system with a 386 processor and the BIOS will only recognize very old hard drives.
2) The original clone was to a fairly new 40 GB drive just to keep the information safe. This drive will boot in a newer Pentium 4 machine so I thought I was safe.
3) After re-cloning to an eBay purchased 83MB drive, which is identical to the failed drive, the system will not boot. I suspect that the MBR is not being correctly installed. I have an error of non-system disk.
4) I have tried fdisk/MBR in DOS but I am not sure that this is doing anything.
5) Changing to a newer BIOS is not an option at this time since this is an embedded controller.
Does anyone have any suggestions?

That's right the drive will boot in a newer machine but not the older one. I did get over my problem though. I was able to restore the MBR only from an old DOS disk. This time the fdisk/MBR function worked. It then booted in the old machine. Thanks for the help though.
