AS/400 Folders Not Recognized in Windows 3.1 386-Enhanced Mode

 * }

Q87977

-

The information in this article applies to:


 * Microsoft Windows versions 3.1, 3.11
 * Microsoft Windows for Workgroups versions 3.1, 3.11

-

SYMPTOMS
IBM has confirmed that when an IBM AS/400 is used as a file server, Windows will not recognize the AS/400 folders when Windows or Windows for Workgroups is running in 386 enhanced mode. However, Windows 3.1 or 3.11 will recognize these folders when running in standard mode.

CAUSE
According to IBM, the problem is due to the AS/400 device drive ECYDDX.SYS, which allocates logical drives.

NOTE: This device driver may prevent Windows for Workgroups 3.11 File Manager from recognizing drive A or B, resulting in the

drive A: or B: does not exist

error message.

MORE INFORMATION
To correct the problem, obtain a Program Temporary Fix (PTF) for the appropriate version, release, and modification level of ECYDDX.SYS. This information can be obtained by typing go licpgm and choosing Option 10 on the AS/400.

To update the system, obtain one of the following files


 * For V2R1M0 use (PTF) SF10163
 * For V2R1M1 use (PTF) SF10165
 * For Extended DOS use (PTF) SF09768

where V is the version, R is the revision, and M is the modification level.

These corrections may be obtained from IBM by using the ECS Modem connected to the AS/400. Please contact IBM if you have further questions regarding this particular problem or how to correct it.
