[Coco] Error 251

[Kip Koon]

Hi Bob,
I don't can't exactly duplicate your setup as I only have Coco 3s with 6809s in them and I don't have an SCII floppy controller, but I can run a CocoSDC in slot 3.  What else do you have in the MPI?

Hi Kip,

I have a Coco3/6309 with 1MB ram. I have a modified MPI, with an SCII floppy controller in slot 4, and my CocoSDC in slot 3.

On the CocoSDC, I have two files for my NitrOS9 setup. The file for /sd0 is "partitioned". Part 1, /DD is 18432 sectors, and part 2, /sda is
503808 sectors. That file is mounted on drive 0. Drive 1 has one file of
477530 sectors. I also use drivewire.
