Hi,
Thanks for the responses. In Suse 10.0, I had edited
/etc/sysconfig/powersave/common
and changed BOOT_LOADER="" to BOOT_LOADER="NONE". So yes, this was not
enabled in the default installation. However, I never had problems
with the file system.
I also had fat32 partitions mounted and both Linux and Windows were happy with
this arrangement (at least for whatever I did, I never made extensive
tests). Can't the two
system save to different swaps as Wilfried suggested and share the
file information via
a common file system? Perhaps there is a problem if there are same
files which are
open in both and not saved?
The advantage of being able to do this (suspending one OS and resuming
another) is
enormous for people wanting to try out Suse and not fully comfortable
with it. And also
for people like me...my wife sometimes want to use Yahoo messenger and
we both have
many apps open in Linux which we don't want to shut and restart.
 Thanks and best regards,
 Pramod
