Late last year I read with interest how Richard Thomsen had installed
a pair of DS QD floppies in his Rainbow, enabling him to read and
write Rainbow and AT floppies. To achieve this, he made extensive
changes to the Rainbow BIOS. From his description, the most daunting
part of this is typing in the source code for the original BIOS
and finding the typos in listings in DEC's technical ref. manual.
Is it possible to avoid this step by disassembling the BIOS using
something like UASM? With this disassembled code, could I then use
Thomsen's DF files to make the required changes? If not, what sort
of difficulties and legalities would be involved in distributing/
selling a program that would make the changes itself? Such a program
could be like the INSTALL programs used to configure programs.
