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

What's the procedure for formatting this drive as a 20 Meg drive. Sounds like you have an older version of the Winchester Utilities disk that DEC shipped. Your simplest solution is probably to find a copy of WUTIL, available from Rainbow bbs's or from the INFO-DEC-MICRO files area, and do a low-level format so it can be used in a Rainbow. Then you can use the DOS FORMAT command to add the system to the hard disk and away you go. >I also have a PC with MS DOS 3.1 and I have been reading that this will run >on the rainbow.

If you want MS-DOS v3.10, buy the Rainbow implementation of it from Suitable Solutions. You've apparently overlooked the fact that (1) the RX50 drives to not automatically handle single density floppies and (2) the hidden/system files on a boot disk provide a machine with its BIOS and are not generally compatible from one manufacturer to another.
