Hi Dave, If we can get the 'No holes' CF card layout to be compliant with cpmtool then that has to be the way to go as it will make life much easier. As I said in a previous post, I welcome this 'no holes' lba to be picked apart to get it right before we go too far down the road and find problems later. I'm a little busy at the moment with various other aspects of my S100 system with the little time I have to spend on it,(summer is coming after all :-) ) If you can knock together a quick image with a CPMLDR.COM and CPM3.SYS (doesnt matter what system it's for) then we could take a look to see how the layout differs. My layout was derived from where CPMLDR was looking to find data. regards David Fry On Saturday, June 14, 2014 7:30:00 PM UTC+1, yoda wrote:
