- AMPRO CP/M FORMAT TRANSLATION UTILITIES
- ---------------------------------------
-
- DESCRIPTION
- -----------
- A pair of AMPRO utility programs -- AMPROCPM.SYS and AMPROCPM.EXE -- allows an
- IBM PC, AMPRO Little Board/PC, or other PC compatible system to directly
- access files on diskettes which have been generated by an AMPRO Z80 Little
- Board (TM) single board CP/M system. (The two utilities can also be used on
- the AMPRO Little Board/186 to read and write AMPRO CP/M diskettes.)
-
- The AMPROCPM software is especially useful for applications in which an AMPRO
- Z80 Little Board is used to generate a data disk which must be read or written
- by an IBM PC compatible system.
-
- The AMPROCPM.SYS driver creates two CP/M access drive letters, corresponding
- to the first and second floppy drive units, on the PC. The desired AMPRO CP/M
- format must be selected under control of a second utility, AMPROCPM.EXE. Both
- 40-track and 80-track AMPRO CP/M formats are included, but your PC system must
- have the appropriate drive for each AMPRO format. Standard 360K 5-1/4" PC
- compatible floppy drives can read the single- or double-sided 40-track AMPRO
- CP/M format; and 720K 3-1/2" or 5-1/4" PC compatible floppy drives can read
- the double-sided 80-track AMPRO CP/M format.
-
-
- Installation
- ------------
- The first step is to install AMPROCPM.SYS, which allows PC-DOS to understand
- the file system used by CP/M. Add the following line to the CONFIG.SYS file
- on the drive from which your PC compatible system boots:
-
- DEVICE = AMPROCPM.SYS
-
- You must reboot your system with this line included in the CONFIG.SYS file,
- for the driver to become installed. Two PC-DOS disk drive letters will be
- assigned by the system to floppy units 0 and 1 as CP/M access drive letters.
- As with other PC-DOS disk device drivers, the two CP/M access drives will
- occupy two sequential drive letters, beginning with the next available drive
- letter beyond those defined other drives and drivers. Typically, on a hard
- disk system the CP/M drives would be "D" and "E".
-
- Example: A system with two floppy drives and a bootable hard disk (floppy
- drive quantity = 2). Using the CONFIG.SYS line given above, the system drive
- letters following boot will be:
-
- A: First PC-DOS floppy drive
- B: Second PC-DOS floppy drive
- C: Hard disk drive
- D: First "CP/M drive" (using floppy drive A)
- E: Second "CP/M drive" (using floppy drive B)
-
-
- Operation
- ---------
- Before you can use either of the "CP/M drives" you must select the desired
- AMPRO CP/M format by means of the AMPROCPM.EXE utility. Simply type the
- program's name on the PC-DOS command line:
-
- A>AMPROCPM<Enter>
-
- The program will display a menu of available AMPRO CP/M formats. Press the
- letter of the format you wish to use. After you select the desired CP/M
- format, the program will exit to the PC-DOS command line. Both "CP/M drives"
- become the same selected format (i.e. you cannot specify two different CP/M
- formats at the same time).
-
- Once the driver is installed and a CP/M format selected, you can use the CP/M
- drives as though they are PC-DOS drives, providing you access them under the
- specially assigned drive letters (usually "D" and "E"). This includes copying
- to and from CP/M diskettes as well as the use of PC-DOS commands. You can
- even use the CP/M drive as a data drive from within application programs.
- Just don't try to run a CP/M program on your PC (on any drive)!
-
- With a drive defined as a "CP/M drive", use the special CP/M drive letter
- whenever you want to access CP/M diskettes, and use the normal PC-DOS drive
- letter ("A" or "B") whenever you want to access normal PC-DOS diskettes on the
- same disk drive. In this manner, you can transfer files freely between AMPRO
- CP/M diskettes and your regular PC-DOS floppy or hard disk drives.
-
-
- AUTOMATIC OPERATION OF AMPROCPM.EXE
- -----------------------------------
- If you want the "CP/M Drive" function to be installed automatically when you
- turn on your system, this is easily accomplished. All you need to do is place
- the appropriate lines in your system's CONFIG.SYS and AUTOEXEC.BAT files:
-
- CONFIG.SYS - As discussed above, include: DEVICE = AMPROCPM.SYS
-
- AUTOEXEC.BAT - Include the following line: AMPROCPM <AMPROCPM.INP
-
- One other thing is needed. You need to create a tiny text file called
- "AMPROCPM.INP" containing a single letter, indicating the particular AMPRO
- CP/M selection desired. For example, if you want to pick menu selection "A",
- the file AMPROCPM.INP should consist of one character: the letter "A". Then,
- menu option "A" will be automatically selected on system powerup. For your
- convience, a sample AMPROCPM.INP with menu option "B" (the most likely) is
- included in the AMPROCPM package.
