5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL

reserve this address space, add the following to your CONFIG.SYS files for the respective memory manager. If a different memory manager is used, find the proper syntax for excluding the space required for the Adapter Card.

EMM386 (Microsoft)

device=C:\DOS\EMM386.EXE X=DC00-DDFF QEMM386 (Quarterdeck Office Systems)

device=C:\QEMM\QEMM386.SYS ARAM=DC00-DDFF 386MAX or BLUEMAX (Qualitas)

device=C:\386MAX\386MAX.SYS RAM=DC00-DE00 (RAM parameter may be in 386MAX.PRO profile)

Netroom RM386 (Helix Software) device=C:\NETROOM\RM386.EXE X=DC00-DDFF

It is also possible that there is a conflict with shadow memory controlled by your PC’s CMOS setup. This is common in Windows 3.1 configurations. Reboot and enter your CMOS setup (typically by pressing a key like <Del>, <F1>, <Esc>, or <F10>) before your PC’s operating system loads. Then locate the shadow-memory settings and adjust them to disable shadow memory in the area used by the Adapter Card.

Another possibility is a conflict with another adapter that uses a large block of memory space or generates a “MEM16” ISA bus signal when the Adapter Card is being accessed. Many 16-bit VGA adapters generate this “MEM16” signal requiring that the Adapter be located outside of the C000-DFFF memory segment. If a conflict occurs, try moving the Adapter to the EC00 memory segment. The following methods will allow the Adapter to be relocated with the different emulation programs.

On the command line type <CTRL> <A> and then the first digit of the memory segment. The following example sets the memory segment at location E.

DP5250 ^AE

IBM Adapter Handler for PC Support

The adapter memory segment, port address, and interrupt level can be set via the following command-line parameters:

E5250AH /M x /I yy /L z

where “x” is the first digit of the memory segment C, D, or E; “yy” is the middle two digits of the adapter port address; and “z” is the interrupt level, 2- 7.
