Re: A windows based program to write a CPM3 image to a CF card for the S100 IDE board


I think the only other file that needs to change is HDRVTBL3.ASM to define the disk.  John can probably speak up if there are other files that need to be modified.

I realize that there are several others working on this presently, but I still wanted to experiment with getting a system to work with dual drives.

Here is what I have done this morning:  took my original single drive HIDE3.ASM and incorporated all the code into it from John's copy ('My CPM System') that was used for the second IDE drive.

My system will boot all the way through and stop after sector 152 (reads all of cpm3.sys) but then I never get the A:> prompt.

Good effort, but I may have to wait for Dave to finish his solution after all.

Hello Dave,
Thanks for your reply - I have been looking at all the code that John has on the site, and had downloaded the version you referenced.  What I wanted to know, for my own curiosity, was If I have a single drive system, would all changes to support the second drive reside solely in HIDE3.ASM?   Would any of the other modules that assemble to CPM3.sys need to be altered?

Thank you for your time and suggestions with this project - I have really enjoyed digging back into this at such a detailed level after all these years.

The code is not in HIDE3.ASM to support both Drive A and B that you have.  You can look at the code at the bottom of John's CPM page that says Most Current HmakeCPM (ABCDEF ...) you can see how it is done (A and F are the IDE drives).  It is not hard and I am adding it to my code (will be A and B for IDE drives) and should have it up on the web this weekend if everything goes well.

Dave or David,
Can either of you tell me if all parameters to support drives A and B in a simple non banked environment reside solely within Hide3.asm?  If not, which other files contain any code required to support drive B.

Thanks and keep up the good work!
