Steps to install new version of os2dump (called newdump)
THIS is a major upgrade to the dump routine. It contains many fixes and
enhancements, particularly support for systems with 64 meg or more installed.
Must be on GA 2.1 or later or OS/2 2.0 at XR06100 level.
This will not work on 2.0 prior to XR06100 or on Warp.
1.To install newdump on hardfile:
in OS/2 2.1 root, enter:
attrib -r -s -h os2dump
copy os2dump *.sav
copy newdump os2dump
attrib +r +s +h os2dump (optional)
REBOOT
2.Once newdump is installed, one can immediately dump to diskette.
To initiate the dump to diskette, hit ctl-alt-numlock-numlock.
** Createdd.exe is no longer needed. **
3.To be able to dump to hardfile the following steps are needed:
NOTE! NOTE! NOTE!
Dump to hardfile must be to a separate, empty partition.
IT WILL ERASE WHATEVER IS ON THE PARTITION.
a.Create a partition about 4meg larger than the amount of memory installed.
*important note* The partition you create has to be addressable by your
system's BIOS. Typically, this restricts you to the first
two physical disks and the first 1024 cylinders thereof.
If you have large disks (>512mb), we suggest you create
the partition at the beginning of freespace.
b.Format the partition FAT
c.Label the partition SADUMP
d.Modify config.sys as follows:
trapdump=off,X: where X: is the partition letter
e.REBOOT
4. If you are using OS/2 2.11 + fixpak XR_a037 or later, the following
new semantics are in effect:
a. TRAPDUMP=ON now does automatic dump for ALL traps/IPEs (not just ring 3).
b. TRAPDUMP=R0 (new) dumps only ring 0 traps/IPEs.
5.To initiate the dump to hardfile, hit ctl-alt-numlock-numlock
16megs should dump in under 30 seconds!!!
A good test would be to run chkdsk on a large enough drive (dont run
chkdsk /f, just chkdsk). Then while chkdsk is still running, initiate
the dump.
6.Some modifications have been made to the dump to hardfile on 8/1/94:
a. A message will now display, informing the user of which partition will
be dumped to, and how much memory.
b. A warning message will display informing the user that the dump will
wipe out the dump partition. The user has 30 seconds in which to
respond. If the user does not answer in 30 seconds, the dump begins.
c. If the user chooses not to dump to the hardfile by answering N to the
above prompt, he is asked if he would like to dump to diskette.
d. If an error is encountered, and the dump cannot proceed to the hardfile,
the user is asked if he would like to dump to diskettes. If the answer
is no, or there is no response in 60 seconds, the system is rebooted.
7.Major modifications were made to both the dump to hardfile and to diskette
on 11/01/94.
a. Improved error checking on dump to hardfile and diskette.
b. More descriptive error messages.
c. NOTE: if there is a bad sector encountered when dumping to hardfile,
a Fatal Dump Error message will display followed by the bad sector
information to help pinpoint the error.
There is currently no error recovery in dump to hardfile.
d. Support for systems with 64meg or more of memory installed.
DO NOT USE a dump dated prior to 11/01/94 on systems with 64 meg or more.
e. Better performance.
f. Improved error recovery from bad diskettes.
8. 11/4/94
In the process of finalizing my code changes 11/3/94 I uncovered a
slight problem if a user tries to dump to an unformatted drive.
Instead of giving a descriptive error message, label SADUMP not found,
it instead gave a FATAL DUMP ERROR!.
In addition, there have been some enhancements to the debugging
capabilities of the dump to hardfile, to enable easier reading of
the debug output.
9. New mods 1/27/94 facilitate dumps to floppy on Compaqs that previously
could dump only to 720k floppies.
