The DBOS runtime system is NOT required for our Win32 products such as FTN95/Win32. We recommend that users with DBOS versions of Salford Fortran upgrade to FTN77 Win32 or FTN95 Win32.

The DBOS runtime system is installed during your compiler installation, if you need to re-install DBOS on your development system we recommended that you re-install the whole compiler package.

To run DBOS under Windows 3.x, Windows 95/98 or Windows Millenium make sure that you use the following configuration. Please remember that DBOS will NOT work under Windows NT or Windows 2000.
DBOS requires the device driver WDBOS.386 to be installed on your machine. WDBOS provides an interface between DBOS and Windows. This driver is also required by ClearWin+ applications running which have been compiled using the DBOS products. WDBOS is loaded through your SYSTEM.INI file. You should have a line similar to the following in the 386Enh section

Code:

SYSTEM.INI
[386Enh]
device=c:dbos.dirwdbos.386

Also please check the advanced properties of the windows shortcut that loads the DOS prompt for the DBOS session. You must ensure that the option "Prevent MS-DOS based programs from detecting windows" is not checked.

Code:

CONFIG.SYS
FILES=30
BUFFERS=30


Scan CONFIG.SYS and AUTOEXEC.BAT for any programs which use extended memory (disk caches, RAM disks, EMS drivers etc.) and make sure that they conform to one of the recognised standards (e.g. VCPI, VDISK or XMS). DBOS is compatible with all of these extended memory management standards.

All DBOS Compilers will work under Windows 95/98 and Windows Millenium, provided your DBOS is version 3.16 or above. If your DBOS version is older than version 3.16 please upgrade to the latest version of the relevant compiler.

Under Windows 95/98, LAUNCHER.EXE is no longer required. You can safely remove this application from the 'startup' folder if you wish.

It is also recommended that you modify the vcache section of your Windows 95/98 SYSTEM.INI file. The following settings are recommended

Code:

SYSTEM.INI
[vcache]
MinFileCache=256
MaxFileCache=3072


This will improve the compile time performance (provided you have at least 16 Mbytes of memory) as more memory will be available to DBOS and the compiler.

Once installed, DBOS can be invoked from the MS-DOS Command Prompt by Typing 'DBOS'.

Remember that DBOS is a TSR program. Once it has been loaded, you do not need to reload DBOS again unless it is explicitly removed by use of the KILL_DBOS command, or a system reboot is performed. DBOS can co-exist with standard DOS software such as editors, spreadsheets, etc.
