Warp 4/WSeB/MCP/ACP Kernels updated

On May 31, 2001 IBM OS/2 Fix Distribution released updated files for the various kernels. They contain fixes since xr_e002/xr_m015/mcp/acp:

-New TrapDump
Bug Fix: JR15030: TRAPDUMP QUERY doesn't show PD
File: DF0508.ZIP
-SES drivers,
See README.SES for details.
File: SES0330.ZIP

File versions :

-WSeb/ACP SMP (D is debug version)
SMP0508.ZIP
SMP0508D.ZIP
-WSeB/ACP Uni/MCP (D is debug version)
UNI0508.ZIP
UNI0508D.ZIP
-Warp4 (D is debug version)
W40508.ZIP
W40508D.ZIP

New function:

1. Support for >64m memory using int15 func e820. Note, this support is enabled ONLY for Intel Pentium Pro or later, or non-Intel Pentium-class machines. This is done in an effort to prevent problems on older PCs.
2. The presence of os2bootos2norev.$$$ suppresses the display of internal revision during boot.
3. Adding "EARLYMEMINIT=TRUE" to config.sys will allow device drivers, etc., access to the memory above 16mb early in boot. Previously, this was only available after DD and IFS init was completed. This has various implications when enabled:

-AHA154X.ADD may do bad things to your system. Don't even enable if using.
-There may be some settings of HPFS386 cache that are incompatible.
-Trap messages will now give the module name instead of the device name. For example, "Exception in module: CLOCK01" instead of "Exception in Device Driver: CLOCK$".
-Traps in 32 bit code now show the modname, too
-Systems with a 486SX chip running FP15 will function correctly. Note, they will NOT work with ACP or (necessarily) on MCP.
-SESDD32 will now work correctly (I hope) for both uni and smp

Bug Fixes:

-JR13335: Some VDMs won't run, complaining of too-long command lines
-JR15194: XCOPY fails with SYS1186 or SYS1192 on (at least) MO drives
-JR15038: Trap 8 in h_DeviceHelpDM running an app from a tcpbeui drive
-JR15229: Files left open after ERROR_TOO_MANY_OPEN_FILES returned to app
-PJ27676: Causes hangs on some systems running UNI or W4 kernels
-PJ27554: Hang or (on allstrict) trap 3 on SMP (only) during beeps
-PJ27678: SMP kernels could not be RIPL-booted. As part of this, there is a new config.sys parameter I13PAGES= available. Adding I13PAGES=1 to config.sys (note, no SET) reduces the memory usage of the mini VDM processes used by ibm1s506.add and the GRADD drivers. This becomes important in RIPL-boot situations.
-PJ27677: SMP systems hang with multiple threads of same process entering a critical section (affects ADSM client)
-PJ27757: Trap 000e running Theseus/4 (note, theseus4.exe may still end up with a sys3175, but at least the system doesn't crash).
-PJ27736: Trap in _PLD_WriteReturnCode
-PJ27777: Set BEGINLIBPATH= (in config.sys ONLY) may be ignored. Also, it would lead to a bogus copy of BEGINLIBPATH= in the environment.
-PJ27906: Trap 000e in pvwRegKrnlInstance running SPM/2 (may also cause unknown odd behavior in other performance monitors).
-PJ27919: Complete system hang running some apps (same as JR12136)

See README in the zip for Install Instructions.

Disclaimer: These interim fixes will be supported by IBM until the next fixpack is available or until superceded by a newer interim fix. At the discretion of IBM, you may be required to revert to GA (i.e. MCP/ACP/fixpack) code to pursue specific support issues.
