New 4/16 MB Token Ring NICs: Problems with LAN Man 1.10 & 2.00

ID Number: Q70697

2.00

OS/2

Summary:

This article addresses problems found when using a particular IBM 4/16

MB Token Ring adapter and any version of Microsoft LAN Manager.

This new IBM adapter can be identified by ROM part numbers 74F9325

(ODD) and 74F9326 (EVEN). This adapter is also 25 percent smaller than

previous IBM 4/16 Token Ring NICs.

When the adapter is used, it will freeze machines intermittently when

accessing resources in the network. This problem occurs on all

versions of LAN Manager.

IBM Corporation is aware of the problem in their microcode and is

distributing new ROMs to correct the above problem. Please contact

your nearest IBM representative to obtain upgrade ROMs.
