Theall) Newsgroups: comp.sys.dec.micro Subject: Replacing RX50's Message-ID: <8801201615.AA04345@ucbvax.Berkeley.EDU> Date: 20 Jan 88 13:39:00 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The ARPA Internet Lines: 14 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. George
