Please note the following corrections to your Tandy 1800 HD Laptop Computer
User's Guide:

Page 75:

The line before the bottom note shows /m=384 as an example parameter.
However, /m= is not a valid parameter and should not be used with your
computer's temm1800.sys device driver.

Page 76:

Delete /m=dddd and the paragraph that follows it. As stated above, /m= is
not a valid parameter and should not be used with your computer's
temm1800.sys device driver.

If you try to use /m=, the computer gives you the error message invalid
configuration.

Please note the following additional information for your Tandy 1800 HD
Laptop Computer:

Powersve.sys Device Driver:

Your computer comes with a power-saving device driver (POWERSVE.SYS). Its
purpose is to save battery power and extend battery life. POWERSVE.SYS is
supplied on the computer's hard disk. To load POWERSVE.SYS, enter the
following line in the computer's config.sys file:

     device=c:\dos\powersve.sys

Notes:

* POWERSVE.SYS might not be compatible with some software.
* If you load POWERSVE.SYS, the computer might require more time to complete
  some operations or run certain software, such as large spreadsheets. If
  the computer takes too much time, remove POWERSVE.SYS from the config.sys
  file.
* Connecting AC power disables POWERSVE.SYS.
