How to change the Hot Keys in Hot DOS. (Version 1.18)
======================================
Does Ctrl-Left Shift conflict with another memory resident program's
hot-keys? If so, you may want to change Hot-DOS's. The procedure is
really quite simple -- ANYONE CAN DO IT! All you need is the copy of
HOTDOS, and the program DEBUG.COM. Assuming that both programs are on
the default drive, type the command below.
DEBUG HOTDOS.COM [Enter]
You will be greeted with a dash prompt and the cursor. If not, type Q
[Enter] and make sure both files are on the current drive.
BY THE WAY: If you ever feel that you have goofed in the
following steps, get back to the dash prompt (Ctrl-Break
should do the trick,) and then type Q [Enter]. That will
return you to DOS without keeping any changes. It also
doesn't hurt to make a copy of HOTDOS.COM on another disk,
to be doubly safe.
Thereafter, issue the following command:
U 440 44B [Enter]
You should see something like this:
xxxx:0440 33C0 XOR AX,AX
xxxx:0442 8EC0 MOV ES,AX
xxxx:0444 26 ES:
xxxx:0445 A01704 MOV AL,[0417]
xxxx:0448 240F AND AL,0F
xxxx:044A 3C0A CMP AL,06
where the xxxx's are some unimportant value. If this is what you see,
then you are in good shape.
Now you need to choose the hot keys you think you want. Here is a
table:
Key Value
------- -----
Alt 8
Ctrl 4
Left Shift 2
Right Shift 1
Choose the hot keys you want, (for an example, I'll choose Alt-Left
Shift,) and add the values together. My example gives me 8 + 2 = 10.
If your number is 10 or higher, (it can be from 1 to 15) you have to
make a minor adjustment. Here is the table to do that:
Number: 10 11 12 13 14 15
New value: A B C D E F
If your number is less than 10, you don't need to do anything at all.
One way or another, remember your number! In my case it is `A'.
Now we're ready to change the hot key. Issue the following command:
E 44B [Enter]
You should see the following:
3AD2:044B 06. (the number you see here should be the same number
as you see in that U command above. Check to make
sure.)
When you feel you're ready, type in the number you came up with, be it
1 through 9, or A through F, and press the [Enter] key. You're almost
done! Two more instructions! they are
W [Enter] (the computer tells you it is writing...)
Q [Enter] (and now you're back in DOS.)
You have just made a copy of HotDOS that will activate using the hot
keys you have chosen. Remember that this copy is not installed yet,
so you will have to reboot the computer and issue the HOT DOS command,
just as the instructions indicate.
...And if everything is correct, you should have Hot DOS at your
finger tips with your new hot key combination. Have Fun.
