OT: Motherboard replacement without reinstalling Opsys

[Manuel Castelao castelao@xxxxxxxx]

Excuse me for going definitely off topic but I would like to hear our
gurus on this matter: is it possible to replace a motherboard without
reinstalling the whole Opsys and apps? If it is necessary to rebuild the
whole system, I am not going to spend time I don't have in that matter
because it's possible to install the opsys again (W2000 in my case) but
all the programs I am running it's too much (configurations, patches,
customizations, etc.). I have seen this page
(http://www.motherboard.windowsreinstall.com/win2k.htm) but I would like
to receive confirmation that it's good and wise advice before getting
myself into really hot water (and with no way back). Maybe someone on
the list has attempted to do that in the past and was successful.
By the way: attempting to prepare the terrain, I ran Partition Manager's
8.01 partition info tool and I received these messages: "Warning #113:
EPBR partition starting at 83538001 overlaps previous EPBR partition",
"Logical starting at 83538126 is not one head away from EPBR" and
"extended volume. Error #114: Logical starting at 100984653 is not one
head away from EPBR". Fortunately, those messages refer to the limit
between a linux swap and a data FAT32 partition, not to the main program
partition (C:) but partition magic is apparently unable to solve the
problem because it sees the whole disk as defective and then I can't
erase those partitions and create them again. Grenier's Test Disk
doesn't detect any problem and I have been working without any problem
for years. Can someone suggest a good partition tool to make a further
diagnostic?

Thank you very much in advance.
