This README file of 22ND2F.EXE accompanies NDINT2F.EXE for NetWare v2.2.
This patch, NDINT2F is intended for NetWare v2.2 for the 5, 10, 50, and 100
user versions. This patch fixes a problem with the int 2F handler on the
non-dedicated DOS process of a file server. For certain values of AH, int
2F will cause the server to ABEND with the message: "Invalid semaphore
state on other process release." This interrupt 2F conflict occurs
between the 286 OS (non-dedicated) and certain other applications that use
2F. The problem was discovered when using a Cobol compiler and Cobol
applications on a non-dedicated server; other applications that require int
2F may also require this patch.
The patch program NDINT2F.EXE is menu driven and contains instructions as
well as an explanation of the patch. To apply the patch to NET$OS.EXE or
NET$OS.OBJ simply run the patch program (NDINT2F.EXE) in the directory
containing the file to be patched.
Installation:
To patch the NET$OS.EXE directly:
1) Make a backup copy of the existing NET$OS.EXE.
2) Copy NDINT2F.EXE onto the diskette where the NET$OS.EXE resides.
3) Execute the NDINT2F.EXE.
4) This patch must be applied each time the NET$OS.EXE is generated.
To patch the NONDEDOS.OBJ file:
1) Make a backup copy of the existing NONDEDOS.OBJ.
2) Copy NDINT2F.EXE onto the diskette where the NET$OS.EXE resides.
3) Execute the NDINT2F.EXE.
4) This patch need only be applied once to create a new OBJ file.
