As I remember it had to do with the fact that I wanted to use the same BIOS for an IDE hard disk I had as well as well as CF Cards (same number of sec/track). Since CPM is capable of using only a very small fraction of a card seemed OK at the time! For the MS-DOS drivers however I use every contiguous sector this is because MSDOS even in its simplest mode can read/write multiple contiguous sectors. While on CF cards. The one thing I have not figured out is some CF cards do not work correctly with the S-100 IDE board. Single or dual versions. The 4GB Kingston CF cards (with the flowers on it): Work fine. As do 8 Gb Maxell, or 4 GB Patrist cards. For example SanDisk cards give errors. I have not been able to figure out what the problem is. Must be some card internal timing/signal requirements.

With his IDE for CF he leaves 64 sectors holes in his data (if I remember right). I had to do some tricks to take images from SIMH and get them to work with the S100-IDE board. I used dd with the "of" parameter to skip blocks on the CF card. I was going to fix the driver so it would use contiguous sectors but just haven't had time to fix it - shame to have a non standard format as presented on the S100-IDE driver. Dave Hi John Since I'm using the 2-port serial I/O board at A0H, with the Z80 cpu and Master monitor, and the 4Meg ram bd (with 2 chips set for 64K RAM), plus your ZFDC and IDE cards and the whole thing seems to be running well with the Monitor... Seems like the time to try to get CPM going. Not sure if your disk images will work, since I think your console is at 0H. I found the CPM source here http://www.uxpro.com/cpm/www.cpm.z80.de/source.html . I know the BIOS has to know the params for my 3.5 or 5.25 in. floppies (not to mention the 80 Meg HD), and I know I have to patch the terminal I/O. Would you have some useful info for me to work from? I tried to read the HD and 3.25 inch DD floppies written my Andrew's SBC system, (which I had no problem building); but I get read errors on these from the S100 system- maybe the disk format is wrong, or the CPM operating system is not where it is expected to be for S100? Also, I used SIMH to patch the MYIDE rom data to test my hard drive, and it seems ok. Help please, if you have some time. I might be able to make CPM go-eventually; but it seems expeditious to ask first. Thank you Leonard Young From: n8ve...@googlegroups.com [mailto:n8ve...@googlegroups.com] On Behalf Of John Monahan Never really used copysys. I seem to remember it counts on a certain disk (sec/track) setup. I just copy User group 0 *.* [S] across and then use HSYSGEN (ZSYSGEN for floppys), which puts system boot on CFCARD or floppy. Remember to do ERA *.* on a new CF card to cleanup the directory sector(s) on a windows formatted card before doing anything else.

Most should be recognizable as well known CPM programs. I just realized that the Hidden/System files may not be on that CF card. Could you check if the file DD.COM (displays all files in a user group) is there. It is a System file so use DIRS to see those. PCGET is used to download a file from a PC (also a system file) should be there, see here:- http://s100computers.com/Software%20Index%20Page.htm to use it. CPM86- brings a ZFDC 8” floppy (only) version of CPM86 CPM86 boots from the IDE Board but also includes 8”&5” disks on the ZFDC board Some of the others… PIP22 is the old CPM V2.2 PIP CPM3-OK.SYS is a backup of CPM3.SYS (in case of screw-ups). CPM3-ZF.SYS boots with ZFDC 8” floppy as the A: drive (For use on floppy boots). FLUSH is just the force a new page on a HP laser printer (using CPM3 P Command) Other non DR programs are to test/use our S-100 boards Andrew & I made. They generally sign on with a menu.

That will be easy, will tell other more to come soon as I/You clean them up On Tue, Nov 20, 2012 at 8:43 AM, John Monahan <mon...@vitasoft.org> wrote: Great Tom, Just FYI, CPM86 files are in user group 1. If you have the setup below along with the 8086 related our boards(s) you should be able to boot directly CPM86 with the file CP/M 3.0 program CPM86.COM . BTW, I had not figured on all those files going out to everybody as is. There are some small test programs in there to test prototype hardware I am working on. Will not make sense and probably crash in other systems.

Insert a CF or SD card into your card reader... (after the program is started) --
