Install PHP for Apache Web Server
This embedded computer supports the PHP option. However, since the PHP file is 3 MB, it is not
installed by default. To install it yourself, first make sure there is enough free space (at least 3 MB)
on your embedded flash ROM).
Step 1: Type ‘upramdisk’ to get the free space ram disk to save the package. Check that you have
enough free space.
