<> I just received a DEC Rainbow 100+ computer. It has both CP/M 80/86 and MS-DOS. I have been trying to use the CP/M assembler for graphics applications, since the GSX-86 graphics package works under CP/M. I have been having trouble with the assembler skipping instructions, and with CP/M not doing what the book says it should. Can anyone give me the names of some good books that explain CP/M and MS-DOS? I do not want the basic "This is a computer, this is a power switch" type books. I want books that explain CP/M for the computer professional. Specifically, I want to know the disk formats for CP/M disks, how the directories are stored on disk, how disk block allocation is done for CP/M, how to call CP/M from assembly language programs, how to modify the operating system to add my own special features, etc. And the same type of information for MS-DOS. I have been programming for over 14 years, and have over 2 years experience with the Intel 8086/88 and 80186/188 family of parts, so I want books that have some depth. Thanks in advance.
