From what I know c31 is a Led code that indicates that the CD-ROm is not bootable, you my try to recreate the CD from the 6-M1 and retry, If there are too many hardeware differences between the 6m1 and the 270, It may not boot. But more than often it is the CD, Try to mount the cd on a seperate (test ) servewr and see iif you could fread the files on it.
