I have successfully (I think) modified my BIOS changes for MS-DOS Version 3.1 for the Rainbow. I have not yet started running under 3.1, since I do not have books on how to use it, and cannot afford to buy one just now. But it boots up and runs some of its programs from floppy disk. I have not yet tried it from hard disk. I have not yet modified the FORMAT program to format my double-sided disks. That is my next project. I modified the BIOS and the MS-DOS bootstrap code. The Z-80 code did not change, so I am using my previously changed versions. Version 3.1 comes with a FDISK program to format the hard disk. Since I use a RD52 (33 MByte disk), I am not sure if it will work on my disk or not, and have not yet tried to use it to get rid of my extra partitions. Does anyone know of a PATCH program for the Rainbow where I can generate patch data for the BIOS and others can use it to patch their BIOS?
