[users@httpd] Query - Apache 2.0.55 vs 2.2

[n3m3s1s 4u]

I have been recently battling to get joomla to work on 2.0.55 due to
.htaccess
I would like to ask that the difference between them as far as Allowoverride
all etc are differrent
on 2.2 you need to edit /etc/httpd/conf/httpd.conf = and add AllowOverride
all in the .htaccess section
on 2.0.55 I try this but to no avail and i just dont know what i am doing
wrong. It just does not do it.
Any ideas?
thanks
