[Coco] Nitros Partitioning

[Bill Pierce]

Dave, that sounds good. We need to move it over to the Coco3FPGA group as to not get everyone here confused.

In fact, I started a partitioning 'fdisk' sort of program for CoCo3FPGA some time ago.  It would be good to discuss this and maybe even work backwards from a functioning SD card with partitions installed (according to the new spec) toward full SD support under DECB.DaveDave Philipsen wrote:I like the idea of having partitions. It's something we need to discussat least for the CoCo3FPGA.  Since the CoCo 3 runs out of RAM anyway itwouldn't be too hard to put DECB, YA-DOS, HDB-DOS, etc. into a loader inthe partition so that the proper "operating system" could be loaded atboot time which would eliminate the need for flashing different ROMimages and flipping switches.DaveOn 3/8/2017 3:12 PM, Brett Gordon wrote:> Gene, Bill.  thanks!
