Fagundo ) Distribution: usa Organization: GenRad Lines: 15 I just got a used Rainbow with a hard drive controller and a dead 10 meg hard drive. I put an ST225 20 Meg hard drive in it, but the software that I have for the hard drive installation only formats the drive as a ten Meg drive. What's the procedure for formatting this drive as a 20 Meg drive. I also have a PC with MS DOS 3.1 and I have been reading that this will run on the rainbow. So, I formatted a floppy on the PC in the following way: FORMAT A:/1/s But when I tried to boot from this floppy the rainbow said it was a non-system disk. Is there a particular way that people ported DOS 3.1 to the rainbow that I do not know about? Any suggestions? Ruben
