mov    ax, 0003h         ; Get_Profile_Boolean
call  dword ptr [_ServiceEntry]  ; service entry point passed to
                                 ; real-mode initialization procedure

Returns a Boolean value from the SYSTEM.INI file. Uses ECX, Flags.

If the carry flag is clear, the ECX register contains either 0FFFFFFFFh or 0h depending on the value of the setting as follows:

Setting	Value
0	0h
1	0FFFFFFFFh
False	0h
No	0h
Off	0h
On	0FFFFFFFFh
True	0FFFFFFFFh
Yes	0FFFFFFFFh

If both the carry and zero flags are set, the setting has no current value and ECX contains the default value. If just the carry flag is set, the specified setting cannot be found.

Must be 0003h.

ECX

Specifies the default value if the setting has no current value. The default value must be either 0FFFFFFFFh or 0h.

DS:SI

Points to a null-terminated string specifying the name of the section to search. If the SI register is zero, the service searches the [386Enh] section.

DS:DI

Points to a null-terminated string specifying the name of the setting to search for.
