I have had the same problem with out using FIXKEYS. In my analysis, the booting program will never work with a correct .IMG file. The error is generated when, if I calculated the address right, the 16 bit word located at offset 508 ( wp[-2] ) is not zero or when the 16 bit word at offset 506 ( wp[-3] ) does not equal the 16 bit word at offset 510 ( wp[-1] ). It appears that wp[-1] is a check sum and wp[-3] is the start of the data segment. I can not see how these words would ever be equal. I have concluded that the MINIX.PRG is the not coded correctly. I have go any further into trying to correct the problem since it is just as easy to boot the system from floppy.
