P60/D system having OS/2 v2-2.1
PROBLEM - P60/D systems having OS/2 version 2.1 installed by a customer from a shrink
wrap package fails to run DOS applications correctly in the DOS box.
Systems AFFECTED - 6384 P60/D only.
SOLUTION - If a P60/D system is loaded with an off the shelf shrink wrap OS/2 version
2.1, the system can experience problems running applications in the DOS box. this is fixed
with a patch diskette available from OS/2 support referencing apar PJ09814.
OS/2 2.1 utilizes the pentium processor's virtual mode extensions (VME). A BUG in OS2 2.1
was discovered in which applications that do their own interrupt management hang on
systems with vme and OS/2 2.1. This affects all pentium and all SL-enhanced 486
systems, a fix for OS/2 2.1 has been incorporated into an update (service pak) which IBM
plans to ship by end of this quarter. The fix will also be in the Q1 manufacturing refresh,
after which all new product is OK.
Applications which allow OS/2 to manage interrupts are not affected. If the P60/D was
purchased with OS/2 2.1 factory installed, the system will not have this problem. The patch
diskette was installed at the factory. Additionally, the patch diskette is shipped with us
machines that are pre-installed with OS/2. This problem only effects P60/D systems when
a new shrink wrapped OS/2 version 2.1 is purchased from a retailer and is installed on the
system. The operating system will install and run except for the DOS box problems
described above. The patch diskette brings the OS/2 operating system from the shrink wrap
package up to the same level that the factory pre-installs. The part number on the patch
diskette shipped with the pre-installed systems is 82G4462. This should be printed on the
diskette.
Permanent fix - Get the patch diskette from OS/2 support and install. OS/2 will be
releasing a new version of the shrink wrap package that will have this fix included. The
release is scheduled for 1Q/94 and is called OS/2 version 2.11.
