This is a 100% working method of having a completely seperate home page for your oscommerce site.
What this means is that your index.php will no longer run the queries for things like "index.php?cpath=" and "index.php?manufacturer_id" thus making it much easier to have a custom layout for your home page.
Instead, these queries will be moved to a new page titled "shop.php"
This means you can make your homepage completely unique, and add what you want.
This works perfectly in conjunction with foxp2's dynamic template system for 2.3.2
1.) Install dynamic template system first from here: http://addons.oscommerce.com/info/7691
2.) then follow instructions from this contribution.
