• COUNTRY = XXX[,YYY]
Specifies the country-specific settings. The default is U.S. This command is required only for
a different country setting.
• DEVICE = driver.ext
DEVICEHIGH = driver.ext
This command causes a device driver to be loaded either low (into TPA) or high (into UMBs).
Drivers cannot be loaded high until both HIMEM.SYS and EMM386.EXE have been loaded
low and DOS=UMB has been specified.
• DOS = [HIGH | UMB ]
This command allows DOS to load information into the HMA (DOS = HIGH), increasing
the amount of TPA available for applications. This command also enables loading TSRs and
drivers into UMBs via the LOADHIGH and DEVICEHIGH commands (DOS=UMB).
Note: DOS = HIGH can only be used if HIMEM.SYS is loaded.
DOS = UMB can be used only if both HIMEM.SYS and
EMM386.EXE are loaded.
• FILES = n 8 ≤ n ≤ 255
Controls the number of files that DOS can open at once. The larger this number, the more
memory DOS allocates for file handles. The default is 8, which is generally inadequate for
most applications and environments. Allocating too many files wastes memory; allocating
too few files may cause an application or environment to fail if it attempts to open too many
files. Unless there is a specific requirement for more files, we recommend using a value of
n=20.
• INSTALL = file.ext
This command loads a TSR from CONFIG.SYS. This command can be used to load TSRs
(low only) that go along with drivers (as a convenience). Note that DOS does not load the
TSRs until the end of CONFIG.SYS (as opposed to where they appear). If you use your
application as a shell (see SHELL=), you can use this command to load TSRs prior to
execution of the application as the shell.
• LASTDRIVE = x
Specifies the number of disk drives managed by DOS. This command is necessary only if the
number of drive letters managed by DOS must be increased. DOS automatically allocates C:
and possibly D:, E: and F:, if additional FLASH disk(s) are present.
