APPENDIX A: Error Codes and Conflict Resolution
For Windows 3.1 systems, use the configuration program (DCFG5250) to change
the adapter’s IRQ setting. For most DOS 5250 emulators and the IBM adapter
handler (E5250AH), you must use their configuration software or command line
parameters (for example, E5250AH /L7).

There are several diagnostic and emulation program messages which will appear
and generally indicate that the required space for the Adapter has not been
reserved or there is some form of memory conflict with the Adapter. Some of these
messages are:
No room in PC address space for 5250 RAM;
-IBM Enhanced 5250 Emulation
TWX 1315 Adapter Random Memory Is Full;
-AS/400 PC Support & CA/400
Error 0005 - The high order bits of the diagnostic test point...
Error 0006 - Adapter RAM visible with POR latch set;
Error 0007 - RAM low address error at offset xxx

Memory conflicts tend to be the second-most-common problems encountered and
are often easily resolved. The most common memory conflict problem is due to
the use of an Expanded Memory Manager in a Windows 95/98 Plug-and-Play
system or the use of an Expanded Memory Manager without the “exclude”
statement.
NOTE
If you are using Windows 95/98 we suggest you disable any memory
manager such as EMM386 in your CONFIG.SYS file by placing a REM at
the beginning of the line and then restarting your PC. After rebooting go
into Device Manager under Control Panel - System and check if the PC
Twinax Adapter Card is working properly. If not, check for resource
conflicts.
Most PCs running Windows 3.1 have an Expanded Memory Manager included.
These memory managers try to maximize the amount of RAM space available for
the system. Your Adapter Card has 8 KB of RAM already resident on the board
which needs to be mapped into the memory space of the PC.
It may be necessary to modify the system’s CONFIG.SYS file in order to reserve this
8-KB block of memory for the Adapter Card. The Adapter is typically located at
DC00-DDFF space but can also be located at CC00-CDFF or EC00-EDFF space. To
