Chapter D - Using Microsoft MS-DOS
BIOS located at 0x00E0000 - 0x00E1FFF
In this example, the GDT BIOS occupies E000:0000 to E000:1FFF (E000 is the segment a d-
dress).
DPMEM at 0x000D0000 - 0x000D3FFF
Here the DPMEM starts at D000:0000 and ends at D000:3FFF (D000 is the segment a d-
dress).
You may also use other utility programs such as Georg Schnurers (ct magazine)
CTPCI
pro-
gram in order to obtain the requested address locations. On this occasion we would like to
thank Mr. Georg Schnurer and the ct magazine for allowing us to put this very helpful utility
on our system disks.
Example 1:
The Microsoft EMM386.EXE Manager is used. The GDT driver GDTX000.EXE has
not been loaded from the CONFIG.SYS:
DEVICE=EMM386.EXE X=D000-D3FF X=E000-E1FF
Example 2:
The Microsoft EMM386.EXE Manager is used. The GDT driver GDTX000.EXE has
been loaded from the CONFIG.SYS:
DEVICE=EMM386.EXE X=D000-D3FF
(Note: You may have to add the path for "EMM386.EXE". Other parameters may follow the
excluded areas).
D.5 Using Windows 3.x
In order to be able to install Windows 3.x a fully operational MS-DOS operating system has
to be present on the chosen partition. Furthermore, the first entry in the CONFIG.SYS file
behind the HIMEM.SYS line has to be:
DEVICE=GDTX000.EXE
(if necessary, add the correct path name after the "=" symbol and before GDTX000.EXE).
(A)
Now install Windows according to the instructions given in the Windows manual. Ge n-
erally, you start with Disk 1 - Setup from which you load the setup program. This Setup pro-
gram guides you through the entire installation and prompts you to insert further floppy
disks.
(B)
After the installation is completed, the Setup program will ask you if you want to reset
the system. This reset must be performed.
(C)
If you change to the directory WINDOWS after the reset and type in WIN<ENTER>,
Windows will be loaded. Although thanks to its high computing power the GDT controller is
just right for disk intensive operating systems such as Windows, it will not show its full c a-
pacity yet. The reason for this is that the "communication" between Windows and the GDT
controller is not yet carried out by GDTX000.EXE, but by Windows' SMARTDRIVE driver.
(D)
The steps in this section aim at removing SMARTDRV from the CONFIG.SYS and AUTO-
EXEC.BAT files, and at adding a few entries to the Windows initialization file SYSTEM.INI.
