Summary:
CodeView for Windows (CVW.EXE) requires a dual monitor configuration.
On most systems, a secondary monochrome display and adapter card meet
this requirement. IBM PS/2 systems are an exception to this rule
because there are currently no monochrome cards that are compatible
with the Microchannel architecture of the PS/2. Because of this,
running CVW on an IBM PS/2 system requires both an 8514/a (PS/2
compatible) card and an 8514/a monitor, in addition to a VGA card and
monitor. Depending on the model of PS/2, the VGA adapter may be
built-in, rather than a separate card.
Owners of non-PS/2 systems may also opt for this configuration because
the resolutions available with the 8514/VGA are higher than with a
color/monochrome setup.
To use this 8514/VGA configuration, the /8 (8514/a) option must
be specified when invoking CVW. In addition, the /B (black and white)
option must be used if a monochrome VGA adapter is used.
In other words, when using a color VGA adapter, CodeView must be
invoked as follows:
CVW /8 appname.exe
When using a monochrome VGA adapter, CodeView must be invoked as
follows:
CVW /8 /b appname.exe
The 8514/a monitor will be the Windows display and the VGA monitor
will serve as the debugging display.
Optionally, the /25, /43, or /50 options can be specified for either
25-, 43-, or 50-line mode, respectively, on the VGA debugging screen.
50-line mode is the default.
For 80386 based systems, the SDK INSTALL program automatically adds
the line "device=windebug.386" to the [386enh] section of the
SYSTEM.INI file for debugging information.
Pages 7-2 and 7-5 of the "Microsoft Windows Software Development Kit
Tools" manual outline the requirements for CVW and for setting up a
dual monitor system, respectively.
