[Coco] HDBDOS - RETRIEVE FIXED!!

[Chad H]

I second this methodology.  Different contributors/developers are undoubtedly working on different aspects.  This holds true be the HDBDOS content or NitrOS9 related, etc.   I believe this has a lot to do with what Bill has just mentioned in another thread concerning "beta" or "experimental" code versus "stable".  

However, while some of the ideas and code we come up with may seem suited for the masses, in which case we SHOULD ensure stability across all the standard platforms pertaining to it, there are other changes we may make that "break the standard" so to speak and may only be suitable for our personal use and NOT for the official distributions of HDBDOS.  I recognize the need to separate the two.  We can only create so many build options after all.

I believe some of the things we are coming up with, atleast for me personally anyways, 'breaks' the build process because it causes the code to grow beyond the 8K standard we are trying to hold onto.  Going over the 8K may be fine on a CoCo 1 or 2, but until we can incorporate some effective bank switching in HDBDOS, the >8K code fails on the CoCo 3.  I look forward to a time when we have the standard 8K version of HDBDOS and then an enhanced 16K version that will allow for increased enhancements and contributions for all.

​Tormod, as of right now I am only making these changes in my test toolshed area that I don't ever push.  Now if these changes to the Makefile other people would like as part of the standard building process of HDBDOS than could do so.  That is only if other people feel this could be useful.

What I have done is created a new file section called %.sdc:
This is actually just a bin file, but without the ROM to RAM and Mover code.  These should be easily usable to flashing the HDBDOS into either the CoCoSDC or into the SuperIDE flash chips.  As far as the SuperIDE goes I have never programmed anything into the flash chip on it so don't know the instructions for it.

To do the sdc files I modified the preload.asm with some IFDEF sections so could build the original preload file as well as the preload8k file without the ROM to RAM and Mover code as well as changing the load address to $4000.


It is still a work in progress right now on my private working area.  I haven't been home much.
