I17HNDLR.EXE
Purpose
This support command is an alternate way to use the INT 17h functions
when the extended BIOS area is disabled (i.e., the jumper at the “X”
position is removed at W12). Also, use this support command to
reprogram the extended BIOS area with another BIOS.
Syntax
I17HNDLR
Remarks
This command is used if the extended BIOS area (D8000–DFFFF) is not
used. The I17HNDLR allows the system to use the INT 17h functions.
LPT1CON.COM
Purpose
This support command redirects the video to the LPT1 port.
Syntax
LPT1CON
Remarks
If you have a keypad and display board and an LCD display connected to
the AUX I/O port, executing the DISPLAY.EXE and LPT1CON.COM
programs allow you to use the display as the system console. You must
reset your system to change the video to the original parameters.
