Hello Gary, the PDF ZFDC.Z80 file is the version 2.9. The contained ZFDC.Z80 in the ZIP file is the version 3.0 from 5/6/2011. In further versions, John adds some new "MS-DOS" controller commands: CMD_DOS_RD_MULTI_SEC EQU 2BH ;MS-DOS, Read data from multiple sectors starting at the CURRENT sector. CMD_DOS_WR_MULTI_SEC EQU 2CH ;MS-DOS, Write data to multiple sectors starting at the CURRENT sector. CMD_GET_SIDE EQU 2DH ;Get the current selected side of the current selected drive CMD_DOS_SET_SECTOR EQU 2EH ;MS-DOS, Set current sector for the next sec R/W
When you call these commands from the 80X86 BIOS/Monitor you get the "3DH" error (CMD_RANGE_ERR EQU 3DH ;CMD out or range). I had asked John for the newest version of the ZFDC.Z80, but he is very busy at the moment. He promised to send the file, when he has time again.
