The new animation and graphics features in the latest grub4dos version is still not quite fully working (the hotkey utility prevents the infinite-cycle animated GIF-on-menu feature from working), but can at least play a sequence of bitmaps smoothly (and with a transparent background if desired!) before the menu is loaded. You can also define up to 4 STAMPn variables to over-stamp your wallpaper with up to four different 'stamps'. It will also be possible to use different stamps for each menu - for instance, when the AntiVirus menu is loaded, it could show the same background but with an AV logo in the corner of the screen instead of the Main Menu logo. I will detail how to do this later.
set GMODE=800
# set a plain colour background
set MYWBMP=0xCC77EE
Graphics mode + plain background
Also, the MYWBMP variable now can be used to define a pure colour background instead of a bitmap or JPEG file. The value must begin with 0x (zero + lower case x) to be recognised as an RGB fill colour (e.g. 0xFF0000 would be red).set GMODE=800
# set a plain colour background
set MYWBMP=0xCC77EE
Use the 'Quick800' template - for quicker loading.
