2500XL  (250-4074)               Utility                Faxback Doc. # 1151

MS-DOS 3.30.11 AND UTILITY EVALUATION 

These utilities are essentially the same as those provided in the previous
version. Verification testing was performed on these utilities with no
problems seen:

    SETUPXL.EXE         configuration program
    SPEEDXL.COM         changes CPU speed until next reboot
    TEMMXL.SYS          LIM 4.0 EMS driver (supplied by Headland)
    KP.EXE              keyboard/mouse password program
    PASSWORD.EXE        power-on password utility

VGA.EXE was changed to support the 132-column modes available in the super 
VGA version of this machine. The 132-column modes do not allow 132 
characters to be typed on a line. The 132 x 25 and 132 x 43 modes actually
display 129 and move the cursor to the next position, but do not allow you 
to type another character.  This has been determined to be a limitation of 
the DOS command line buffer and not related to the 132 column modes.

If MSDOS 3.30 version of ANSI.SYS is used with the 132 x 43 mode only 24 
lines of the screen are used with normal scrolling occurring in those 24 
lines. If MSDOS 4.01 version of ANSI.SYS is used with the same mode 24 
lines are displayed then all subsequent display to the screen overwrites 
the last line and no scrolling occurs.

All utilities functioned as expected with one exception:
The 132-column modes available through VGA.EXE did not work properly with
ANSI.SYS. See details above.
