BOL is your friend:
http://msdn2.microsoft.com/en-us/library/aa933149(SQL.80).aspx
According to my 2000 BOL the maximum was 256 in 2000 as well. I can't say
I've ever put those limits to the test.
It is often recommended that you should aim to have the same number of files
as you have processors. On that basis you would be unlikely to need as many
as 256 filegroups.

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.
SQL Server Books Online:
http://msdn2.microsoft.com/library/ms130214(en-US,SQL.90).aspx
--|||Actually there were 256 in SQL2000. In 2005 there are 32,767.

The 2000 Books Online claims that max number of filegroups per database is 2
56. Did you try to
create more than 16? Either we have an error in Books Online, a bug in the p
roduct or perhaps you
was misinformed?

In regards to the processors, I would point out that this should be
read as relating to the number of processors for *active* filegroups,
you may want some more to hold archive stuff, and to facilitate
backups, to support partitioned tables, and to map to different
classes of storage (RAID 1,5,10).
All those good reasons, and I've never really played much with it
myself!
