The following tables cross-references some of the public fix packs and GA versions of OS/2 with their internal kernel build level.
Notes:
Some fix packs use the same kernel build level when updates are confined to modules other than OS2KRNL.
The build level for a system may be determined using the command:
VER /R
The build level of a system module may be determined using the command:
BLDLEVEL <file name>
The fix pack level for a system may be determined using the SYSLEVEL command. The following example shows the system level information for OS/2 Warp V4.0 fix pack 6:
        C:\OS2\INSTALL\SYSLEVEL.FPK
                                   OS/2 Warp 4 Service Level
        Version 1.00     Component ID 566933010
        Type Fixpak
        Current CSD level: XR0M006
        Prior   CSD level: XR0M006
