• DEVICE = driver.ext
DEVICEHIGH = driver.ext
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 are loaded low and
DOS=UMB is specified.
In addition to the DEVICEHIGH lines required to support CardSoft (refer to the CardSoft
3.1 User's Guide), you have the option of setting the number of sockets that support ATA
and/or SRAM cards. Use the following formula to calculate the number of drive letters that
will be used by CardSoft:
# of drives available to CardSoft =
(# of sockets for ATA cards) + (# of sockets for SRAM cards)
using the following table as a guide.
# of Sockets Set
1
Add the line:
devicehigh=c:\cardsoft\atadrv.exe/S:X
where X is the number of sockets to be available to CardSoft.
• DOS = [HIGH | UMB ]
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
