- (1) General Information of 700PRO.EXE (OS/2 PM program)
-
- - This program was prepared for IBM ThinkPad 700C/720C.
- This program does not work on IBM ThinkPad 700/720.
-
- - This program:
- - was prepared for a customer who uses ThinkPad 700C/720C
- as a presentation tool at conference.
- (LCD is for an operator of ThinkPad 700C/720C and external CRT is
- for audience)
- - is helpful to those who share the same screen of LCD and CRT.
- - enables an operator to turn on/off external CRT.
- - enables an operator to see the CRT status by minimized icon.
- - enables an operator to set the maximum brightness of the LCD.
- There are two levels of maximum brightness - "Economy mode"
- and "Normal mode". Economy mode gives longer battery operation.
- This selection does not affect the brightness of CRT.
-
- - LCD and CRT selection can be done by PS2.EXE program as well.
-
- "CRT (Enhanced)" mode is found in the selection of PS2.EXE.
- It is recommended not to set and save "CRT (Enhanced)" mode
- when you use 700PRO.EXE because "CRT (Enhanced)" mode was
- prepared to enable CRT resolution over 640x480. Please note that
- LCD resolution is limited to 640x480.
-
- (2) Information to install 700PRO.EXE
-
- Before running 700PRO.EXE program, you must check CONFIG.SYS file!
- "IOPL" must be set to "YES". It seems that OS/2 2.0/2.1 default is set
- to "YES", thereby most of the user does not need to edit the CONFIG.SYS
- file, but please confirm the following in CONFIG.SYS file.
-
- IOPL=YES
-
- If not YES, please change to "YES".
-
-
- (3) How to use 700PRO.EXE
-
- Please use mouse or ThinkPad TrackPoint.
- (I did not implement keyboard input to control CRT on/off and LCD
- maximum brightness control.)
-
- When no CRT is attached physically, please do not select "LCD+CRT".
- When "LCD+CRT" is selected, control circuits of CRT port consumes
- battery power. It shortens the batter operation.
