Date: Wed, 21 Feb 2001 09:42:35 -0500 From: madodelatptdprolog.net Subject: [VOICENWS] New Warp Kernels From: "Paul Smedley" There is a new series of Feb 20th Kernels located at ftp://testcase.boulder.ibm.com/ps/fromibm/os2 - Haven't installed the Warp 4 one yet, so no idea what's changed! Regards, Paul. Moderator note: Please remember that anything from IBM's Testcase site is unsupported unless IBM has instructed you to use it. These kernels are for testing recent updates. Don't use them in a production environment until you are sure they are without problems. You have been warned. Here is the readme for these new kernels as posted on comp.os.os2.bugs: ------------------------------------------------------------------------------ This contains fixes since xr_e002/xr_m015/mcp/acp. Important note: If you use the OS/2 SES facility, you need a new sesdd32.sys dated 6 Feb 2001 or later to use this kernel. Also, a new dump formatter (df_ret.exe) dtd 6 or 7 Feb 2001 is required, if you want to analyze a dump from this kernel. 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 \os2\boot\os2norev.$$$ 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: a) large VDISKs are possible. I tried DEVICE=\os2\vdisk.sys 16000 b) AHA154X.ADD may do bad things to your system. Don't even ask. c) There may be some settings of HPFS386 cache that are incompatible. This feature is experimental. 4) 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$". Unfortunately, traps in linear code will still be somewhat "mysterious". Bug Fixes: Fixed a trap 000d in w_OpenCreate (140:4dfd or so in uni/w4 krnls, don't have regs for SMP). This was a post mcp/acp regression Fixed strange loader i/o problems specific to the 0111 kernel. Fixed a bootup sys31xx problem specific to the 0123 kernel. Fixed a problem that was (I think) specific to Janauary uni & W4 kernels which resulted in odd ring 3 (maybe ring 0?) traps and hangs Fixed some trap and other peculiar problems specific to the 0206 kernel. Those were the result of a build problem. JR15494: Delayed response of Ctrl-C or Ctrl-S (pause) in os/2 windows JR15405: (probably) DosQueryAsyncTimer fails on timecritical thread after mscount rolls over after 49.7 days of uptime JR15030: TRAPDUMP QUERY doesn't show PD (needs a new trapdump.exe, too) 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 PJ27700: SMP systems may get a trap 000e in _tkStopScan, particularly during a procdump operation. 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. It may be helpful for UNI RIPL boot, as well. 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). Following are rough instructions for applying the os2krnl fix: In the directory from which you boot (C:\ or d:\ or whatever), type these commands. Note that os2krnl should have come with this file. 1. attrib -r -s -h os2krnl 2. attrib -r -s -h os2ldr 3. copy os2krnl os2krnl.sav 4. copy os2ldr os2ldr.sav 5. copy \os2\system\trace\*.tdf \save (or wherever) 5. unzip -o xxx.zip If you want, you can turn the os2krnl and os2ldr attributes back on, but it's not necessary to do so. Trace files (*.tdf) have been included. An os2krnl.sym file has been provided with this fix. Just save it somewhere (root directory or anywhere). It is only needed in case OS/2 service requests a standalone dump of your system in the future. ----------- To unsubscribe yourself from this list, send the following message to majormajoratos2voice.org unsubscribe news end If you have an announcement you would like posted to the VOICE News list, please send it to submitatos2voice.org.
