or if the shell is located in a directory other than the root directory of the boot drive.
• SHELL = file.ext
Specifies the command shell to be used. The default command shell is COMMAND.COM

For additional information, consult the MS-DOS User's Guide.
To run (and store) COMMAND.COM in a directory other than the root directory (see also
SET COMSPEC= above)
Note: TCM automatically puts COMMAND.COM in the root directory of a
FLASH disk marked as bootable, so this should seldom be needed.
• To use an application other than COMMAND.COM as the shell.
• STACKS = n, s0 ≤ n ≤ 64, 32 ≤ s ≤ 512
Controls the number and size of the DOS stacks used to service hardware interrupts.
Unless there is a specific requirement otherwise, we recommend using a value of n=9 and
s=256 to save memory.
