All, I am appealing to the Group once again as I am at a roadblock.
My system is as follows: Compupro CPUZ Compupro System Support 1 Compupro Ram 17 IDE CF ZFDC The system boots CPM3 from the IDE CF board with drives A and B. The ZFDC is configured as C and D with both drives being 1.44MB 3.5" floppies. Here is what happens: I can select, format and write to the floppy. I can copy files to and from the floppy. I can do anything I want, up to and including *RESET* of the system. *However*, if I turn the power off and re-boot then the diskette previously written cannot be 'logged to'. If I type C: I get an I/O error. If I insert a diskette written on another system (like DOS) I can log to it just fine. Even if I go back into the ZFDC Diags and set the drive format etc. it still fails. It only works if I format the diskette and never power down. So, the fact that the system will read a disk written under DOS tells me there must be something I am doing wrong in the write process that is not affected by a RESET, but is lost with POWER off. Does anyone have this working and can offer any suggestions? I have been over and over the BIOS code and can find nothing wrong.
