    Install yaze-ag-2.20:
    =====================

    Sections:

    	1. SOLARIS 8 (Sparc)
    	2. LINUX
    	3. FreeBSD
    	4. Cygwin (Windows)
    	5. Mac-OS-X (not yet ready)

    1. If you want to run yaze-ag under SOLARIS 8 (Sparc) then
       (gcc 3.x.x)

    	copy  Makefile_solaris  to  Makefile

    	edit Makefile in the section optimizing: Refer the
    	switches -mcpu in "man gcc" and set the switches
    	like your hardware (default: v9)

    	then call "make"

    	If you want to install the emulator in the system read the
    	notes above in this document.
    	To install the files in /usr/local/bin and /usr/local/lib/yaze
    	give the command "make install" as root.

    2. If you want to run yaze-ag unter LINUX then
       (gcc version 3.3 20030226 (prerelease) (openSuSE)

    	copy Makefile_linux  to Makefile

    	edit Makefile in the section optimizing:
    	Refer the section optimizing (gcc 2.x.x and gcc 3.x.x) and
    	set -march like your hardware (default: -march=pentium3)

    	then call "make".

    	If you want to install the emulator in the system read the
    	notes above in this document.
    	To install the files in /usr/local/bin and /usr/local/lib/yaze
    	give the command "make install" as root.

    3. If you want to run yaze-ag under FreeBSD then

    	copy  Makefile_freebsd  to  Makefile

    	edit Makefile in the section optimizing:
    	Refer the section optimizing (gcc 2.x.x and gcc 3.x.x) and
    	set -march like your hardware (default: -march=pentium3)

    	then call "make".

    	If you want to install the emulator in the system read the
    	notes above in this document.
    	To install the files in /usr/local/bin and /usr/local/lib/yaze
    	give the command "make install" as root.

    4. If you want to run yaze-ag under Cygwin (Windows) then
       (gcc version 3.3.2 (cygwing special))

    	copy  Makefile_cygwin  to  Makefile

    	edit Makefile in the section optimizing:
    	Refer the section optimizing (gcc 2.x.x and gcc 3.x.x) and
    	set -march like your hardware (default: -march=pentium3)

    	then call "make".

    	If you want to install the emulator in the system read the
    	notes above in this document.
    	To install the files in /usr/local/bin and /usr/local/lib/yaze
    	give the command "make install".

    4. If you want to run yaze-ag under Mac-OS-X then
       (gcc ?.?.?)

    	You have to use the Makefile_solaris

    	Refer to section "SOLARIS".

    	Which switches are to set, that I don't know at this time.

    Notes if you want to install yaze-ag in your system
    ===================================================

    "make install" do following:  (BINDIR, LIBDIR ... are defined in the Makefiles)

        in BINDIR
    	install yaze_bin	(yaze-ag executable (the Z80 emulator))
    	install cdm		(CP/M Disk Manager)
    	install yaze		(a shell script which copies some CP/M disks
    				 if necessary and starts yaze_bin, see yaze(1))
    	symbolic link  cpm --> yaze
    	symbolic link  z80 --> yaze

        in LIBDIR
    	install yaze-cpm3.boot	(bootsys + cpm3.sys) (ZPM3)
    	install yaze.boot	(Superdos a CP/M 2.2 replacement)

        in MANDIR
    	install yaze.1		(man page of yaze-ag)
    	install cdm.1		(man page of the CP/M Disk Manager)
    	install cpm.1		(reference to yaze.1)
    	install z80.1		(reference to yaze.1)

        in DSKDIR
    	Install some disks which are copied by the shell script "yaze"
    	to $HOME/cpm if necessary (have a look to yaze(1) ).

        in DOCDIR
    	install the whole documentation there. The shell script "yaze"
    	makes links to this documents in $HOME/cpm/doc.

        in DOCHTMLDIR
            install the whole documentation there in HTML format. The shell
            script "yaze" makes links to this documents in $HOME/cpm/doc_html.

    How do you start yaze-ag?
    =========================

    Start YAZE-AG-2.20 with the shell script "yaze". Look to yaze.1 or
    yaze(1) (man yaze) it describes also the strategy of the shell script yaze.

    If you does no changes in the Makefile yaze-ag (yaze_bin) will be compiled
    with the options -DMMU and -DBOOTSYS. So yaze-ag will load and run
    yaze-cpm3.boot at 0100H (BOOTSYS.com+CPM3.SYS) instead of yaze.boot (CP/M 2.2).
    If the option -DBOOTSYS is deleted yaze-ag starts CP/M 2.2 (yaze.boot) - then
    you can start CP/M 3.1 by simple running cpm3.com (the unix file yaze-cpm3.boot
    is the same as cpm3-ok.com).

    If you delete the option -DMMU yaze-ag can run only CP/M 2.2 (yaze.boot) then
    you have to delete -DBOOTSYS too.

    Dokumentation
    =============

    Look to 00-INDEX.doc it describes the several document files!

    The whole dokumentation are in yaze-ag.doc, yaze.doc and the README's,

    Yaze-ag.doc and README_BOOTSYS describes my new CP/M 3.1 Bootloader BOOTSYS and
    describes why I had to developed BOOTSYS and how BOOTSYS works.

    README_BIOS3_Z80 describes the Z80 ASM-files of the CP/M 3.1 BIOS on drive P:
    which act as an interface to the yaze-bios (bios.c).

    On every yaze-disk is a file with the name "0-README.1ST". This file describes
    the contents of the disk.

    Let me know if you test yaze-ag-2.20 or if you find an error or you miss a
    feature. Feel free and send an email to me.
