Configure a startup menu with a background for agFM

Currently, the agFM menu system can either use the internal theme ('slack') or you can switch it to Terminal mode

However, you can define a startup menu and populate the menu entry with specific payload entries of your choice.

The startup menu will use the same 'slack' theme, but you can change it to use a non-themed menu.

You can specify the resolution (1024x768 recommended), text colours and either a pure colour background or a wallpaper image (stretched or normal and you can use .png, .tga, .jpg or .jpeg).

Note that the text colours that you set will also be used if you set Terminal mode (F4 - T):

Here is an example:

\boot\grubfm\startup_menu.txt

#Rename this file to startup_menu.txt to be active.
#Displays up to five menu options (uncomment lines and change paths as required).
#Menu items are only listed if the file exists.
#type can be e2biso to boot immediately using partnew or wininst for Windows Install ISO or do not set a type to allow user choice from menu.
#for .cfg and .imgptn files, do not set a type and they will auto-run.

#Uncomment the line below if you want agFM to show all files in each folder on startup
#grubfm_set --hide 0

############ USER MENU CONFIG ############
