†
emurst.exe resets the ’C2xx emulator
optional files † emuinit.cmd is a general-purpose batch file that contains debugger
commands.The version of this file that’sshipped with the debugger
defines a ’C209 memory map. If this file isn’t present when you first
invoke the debugger, then all memory is invalid at first. You
must
modifythisfiletomatchyourtargetsystem’smemorymap.Forinfor-
mationaboutsettingupyourownmemorymap,refertothe

.
†
init.clr is a general-purpose screen configuration file. If this file isn’t
present when you invoke the debugger, the debugger uses the
default screen configuration.
†
init.25 and init.50 have been provided for basic 80x25 and 80x50
screen sizes, respectively. The init.clr file brings up the debugger in
80x25 mode. To bring the debugger up in another mode, copy one
of the init.xx files to the init.clr file.
†The default configuration is for color monitors; an additional file,
mono.clr, can be used with monochrome monitors. When you first
invoke the debugger, the default screen configuration should be
sufficient for your needs. Later, you may want to define your own
custom configuration.
For information about the screen configuration files and about set-
ting up your own screen configuration, refer to the

emulator.
Preparing the XDS510-PC for installation
BeforeyouinstalltheXDS510-PC,youmustbesurethattheboard’sswitches
are set to correctly identify the I/O space that the board can use.The emulator
uses 32 bytes of the PC I/O space; two switches on the board identify this
space.
Figure 1–1showswheretheseswitchesareontheXDS510-PCandidentifies
the switch numbers.
Switches are shipped in the default settings shown here and are listed in
Table 1–1. If you use an I/O space that differs from the default, change the
switch settings. Table 1–1 also shows alternate settings.
In most cases, you can leave the switch settings in the default position.
However, you must ensure that the emulator I/O space does not conflict with
other bus settings. For example, if you’ve installed a bus mouse in your sys-
tem,you may not be able to use the default switch settings forthe I/O address
space—themousemightusethisspace.RefertoyourPCtechnicalreference
manual and your other hardware-board manuals to see if there are any I/O
space conflicts. If you find a conflict, use one of the alternate settings shown
in Table 1–1
.

1) To minimize the risk of electric shock and fire hazard, be sure
that all major components that you interface with Texas Instru-
ments devices are limited in energy and certified by one or
more of the following agencies: UV, CSA, VDE, or TUV.
2) To minimize the risk of personal injury,
always turn off the
power to your PC and unplug the power cord before installing
the XDS510-PC.

Step 1: Installing the XDS510-PC in Your PC
1-6
Setting the XDS510-PC into your PC
After you’ve prepared the XDS510-PC for installation, follow these steps.
1) Turn off the power to the PC, and unplug the power cord.
2) Remove the cover of your PC.
3) Remove the mounting bracket from an unused 16-bit slot.
4) Install the XDS510-PC in a 16-bit slot (see Figure 1–2).
5) Tighten down the mounting bracket.
6) Plug the target cable into the XDS510-PC (see Figure 1–3). The cable is
a 25-pin DSUB connector, shaped to ensure proper connection.
7) Replace the PC cover.
8) Plug in the power cord, and turn on the power to the PC.

1-9 Installing the Emulator and C Source Debugger With OS/2
1.4 Step 3: Installing the Debugger Software
This section explains the process of installing the debugger software on a
hard-disk system.
1) Make a backup copy of the OS/2 debugger product disk. (If necessary,
refer to the OS/2 manual that came with your computer.)
2) On your hard disk or system disk, create a directory named
c2xxhll . This
directorywillcontainthe’C2xxCsourcedebuggersoftware.Tocreatethis
directory, enter:
MD C:\C2XXHLL
3) Insert the OS/2 debugger product disk into drive A. Copy the contents of
the disk:
XCOPY /V /S A:\*.* C:\C2XXHLL
The OS/2 version of the debugger executable is called emu2xxo.exe. If
youdon’tplantoinstalltheMS-Windowsversionofthedebuggersoftware
inthec2xxhlldirectory,youcanrenametheOS/2versionoftheexecutable
to emu2xx.exe.
4) Includeoneentryforeach’C2xxdebuggeronyourscanpathineitheryour
Start Programs menu or a Group menu. (Refer to your OS/2 manual for
instructions on adding a new program to your Start Programs or Group
menu.)
1.5 Step 4: Setting Up the Debugger Environment
To ensure that your debugger works correctly, you must:
- Modify the PATH statement to identify the c2xxhll directory.
- Define environment variables so that the debugger can find the files it
needs.
- Identify any nondefault I/O space used by the emulator.
- Set the IOPL option. (This can be done only in your config.sys file.)
- Reset the emulator.
Not only must you do these things before you invoke the debugger for the first
time,
you must do them any time you power up or reboot your PC.
You can accomplish most of these tasks by entering individual OS/2 com-
mands, but it’s simpler to put the commands in your config.sys file or a sepa-
rate batch file.

Figure 1–6 (a) shows an example of a config.sys file that contains the sug-
gestedmodifications(highlightedinboldtype).Figure1–6

batch file that you could create instead of editing the config.sys file. (For the
purposeof discussion,assumethat this samplefileis namedinitdb.cmd.)The
subsections following the figure explain these modifications.

Invoking the new or modified batch file
- If you modify the config.sys file, be sure to invoke it before invoking the
debugger for the first time. To invoke this file, reboot your PC.
- If you create an initdb.cmd file, you must invoke it before invoking the
debugger for the first time. After that, you’ll need to invoke initdb.cmd for
each session in which you want to use the debugger. To invoke this file,
enter:
INITDB
