- What this package contains:
- ===========================
-
- This package contains video utility programs for use ONLY
- with the ThinkPad 350/350C & PS/Note 425/425C systems.
-
- Each utility is designed to provide a single feature or
- workaround for a common problem, & is described in detail
- in the following section. Additional utility programs
- may be added to this package from time to time.
-
- Use of these programs on any other system may result in
- unpredictable results.

- Program Descriptions (& package history):
- =========================================

- (All programs copyright IBM Corporation)

-
- Package version 1.0, 94/05/03:
-
-
- 1IFIX.EXE v1.0 (DOS)
- ------------------------
-
- A problem exists with the AF4US1I system BIOS, where text
- character descenders may be lost (the bottom-most portion
- of lower case 'g', 'j', etc.). This occurs when a system
- with the "1I" BIOS is started with the Vertical Position
- set to "Top", "Center" or "Bottom". This problem will not
- occur if the Vertical Position is set to "Expand".
-
- The Vertical Position setting & BIOS level can be checked
- within the Configuration Utility (Fn+F1), pages 2 & 3,
- respectively.
-
- The current workaround is to use the Configuration Utility
- to set the Vertical Position to "Expand", exit the utility
- (select "Yes" to save changes), then re-enter the utility
- & reset the Vertical Position to the desired setting (saving
- the change again). This procedure must be repeated each time
- the system is started 'cold' (power switch) or 'warm'
- (control-alt-delete).
-
- For DOS users, simply add the 1IFIX.EXE program to your
- AUTOEXEC.BAT file, & the descenders will be restored properly
- without having to perform the above workaround. This routine
- is **not** resident & requires no system resources when it
- has finished executing. There are no command line switches
- for this routine.
-
-
- VGAONLY.COM v1.0 (DOS)
- --------------------------
-
- Some DOS programs may incorrectly "auto-detect" the highest
- possible display resolution. Some programs have been found
- to incorrectly select 800x600 resolution when running on the
- LCD (which is limited to 640x480). A stable display will
- result, but a portion of the screen on the right & bottom
- edges will not be visible.
-
- Some programs will allow the user to "force" the display to
- a particular resolution, & if available, that method should
- be used. For programs which do not offer this option, &
- which incorrectly select the 800x600 modes, the current
- workaround is to run the program with an external display
- attached (which is capable of 800x600).
-
- VGAONLY.COM is a TSR (terminate & stay resident) program
- which will intercept video mode set calls & reject any
- request for modes higher than VGA (640x480). This program
- will **usually** inhibit DOS programs from incorrectly
- selecting a video mode which is incompatible with the LCD.
- There are no command line switches for this routine.
-
- This program should be used ONLY WHEN NECESSARY for specific
- DOS programs. It can only be removed from memory by restarting
- the computer - either 'cold' (power switch) or 'warm'
- (control-alt-delete) restart.
-
- If you are using Windows (tm) with a high resolution video
- driver (anything greater than 640x480 & 16 colors), & you
- forget to remove this program, Windows will not start.
- You will see a message similar to:
-
- Error: Video BIOS does not support this mode.
- << Press any key to continue >>
-
- Simply reboot your system to remove the VGAONLY TSR, then
- restart Windows.
