This update for Norton Utilities version 7.0 provides support
for the newly released Stacker version 3.1. Stacker 3.1 now
interacts with DOS 6 in the same way as Microsoft's DoubleSpace,
and can quickly convert DblSpace drives to Stacker drives by
updating the compressed drive header and only converting the
data over time as it is accessed. DOS 6 loads the driver BEFORE
the CONFIG.SYS file is executed. This allows the CONFIG.SYS and
AUTOEXEC.BAT files to be placed on the compressed drive.
The following programs are affected by the new Stacker 3.1:
NDIAGS - Changes the Comprehensive Memory Test so it can
temporarily replace the CONFIG.SYS. file. The
new NDIAGS is NOT in this update. It is provided
in a separate update file - NDIAGU.EXE.
SFORMAT, RESCUE,
RESCUE.INI and
NUCONFIG - Changes how these programs find the CONFIG.SYS
and AUTOEXEC.BAT files for copying and changing.
NDD - Supports drives converted from DoubleSpace to
Stacker 3.1.
SPEEDISK - Supports drives converted from DoubleSpace to
Stacker 3.1 by fully converting the DoubleSpace
compressed drive to Stacker 3.1 format prior to
defragmenting the drive. This process is
reported by a dialog message. The conversion
process can take several minutes or more
depending on the amount of compressed data that
needs to be converted.
INSTALLATION INSTRUCTIONS
-------------------------
To update the current version of NU 7, copy the three files,
NU7UP.BAT, NU7UPD.EXE and NU7.RTP, to the directory containing the
original copy of Norton Utilities Version 7.0. Then type:
NU7UP <ENTER>
A new BACKUP sub-directory will be created containing your original
programs, in case you need to return to the original versions.
IMPORTANT! If you reinstall NU7, you must reinstall this update.
Before reinstalling this update by running NU7UPD, you must delete
the files in the BACKUP directory. NU7UP.BAT will do this for you.
UPDATE DETAILS
--------------
After installing this update, the SFORMAT, RESCUE and NUCONFIG
files will be about 90-95K larger than the originals. In order
to provide this update electonically, these files had to be
made independent of the NLIB100.RTL file. This greatly increased
their size. Because passwords are stored in the NLIB100.RTL file,
NUCONFIG and SFORMAT can no longer be password protected.
