The Get_Profile_Boolean service returns the value of an Boolean entry in the
SYSTEM.INI file. The Profile and Keyname parameters specify the section and
entry to search for.
 
This service is only available during initialization.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
Default    Specifies the default value to return if the entry is not found,
           or has no current value.
 
Profile    Specifies a null-terminated string identifying the section in the
           SYSTEM.INI file to search. If Profile is zero, the service
           searches the [386Enh] section.
 
Keyname    Points to a null-terminated string identifying the name of the
           entry to search for.
 
Return Value
 
If the carry and zero flags are clear, the specified entry is found and is a
valid Boolean string. In this case, the EAX register is set to -1 or 0
indicating that the entry value evaluates to true or false, respectively.
 
If the carry flag is clear and the zero flag is set, the specified entry
exists but has no corresponding value. If the carry flag is set, the entry
cannot be found or the entry does not represent a Boolean value. In these
cases, the EAX register is set to the Default value.
 
Comments
 
This service returns the Default value unless the value corresponding to the
specified entry is a valid Boolean string. A Boolean string can be one of
the following:
