The problem is with the format of the disk that was used to hold the new version of MINIX. I went in with a sector editor and changed the GEM file of the MINIX.IMG so that the last 16 bit word of the first sector equaled the third from the last 16 bit word. There were no problems. ( The original disks I got from PH had $01D0 for this value ). The reason this problem comes up is that the last word in the first sector is a GEM/TOS check sum. GEM/TOS tries to creat a different serial number for each disk that it formats. (random number perhaps) This cause the last word to be different for each disk, even when an identical copy is made by dragging the icon for one disk over the other. It is apparent that the first sector is not copied. Note. that this problem does not happen if the formating program that was just relased over this net is used to format a disk from MINIX!!!
