REBOOTING AN IBM PC FROM A BATCH FILE
|
|||
|
|
|
|||
|
|
|
|||
|
|
When using SUPERSPL or SUPERDRV, a specified amount of memory is
|
|||
|
|
extracted from system use. The only way to return the memory for
|
|||
|
|
system use is to reboot DOS, because of the lack of support from
|
|||
|
|
DOS.
|
|||
|
|
|
|||
|
|
This may be undesirable for those who wish to operate under batch
|
|||
|
|
files or menus.
|
|||
|
|
|
|||
|
|
Below is a procedure to create REBOOT.COM, a program when
|
|||
|
|
executed will reboot the machine.
|
|||
|
|
|
|||
|
|
To create REBOOT.COM, enter the following at the DOS prompt:
|
|||
|
|
|
|||
|
|
DEBUG <Return>
|
|||
|
|
N REBOOT.COM <Return>
|
|||
|
|
A 100 <Return>
|
|||
|
|
MOV AX, 0040 <Return>
|
|||
|
|
MOV DS, AX <Return>
|
|||
|
|
DS: <Return>
|
|||
|
|
MOV WORD PTR [0072], 1234 <Return>
|
|||
|
|
JMP FFFF: 0000 <Return>
|
|||
|
|
<Return>
|
|||
|
|
R CX <Return>
|
|||
|
|
11 <Return>
|
|||
|
|
W <Return>
|
|||
|
|
Q <Return>
|
|||
|
|
|
|||
|
|
You now have a file called REBOOT.COM on the default disk.
|
|||
|
|
|
|||
|
|
To reboot, just enter the name REBOOT at the DOS prompt, or in a
|
|||
|
|
batch file.
