It does not display icons for HaikuOS and FreeDOS

[emartisoft]

My Laptop has 4 OSs. It displays menu icon for WindowsXP and Ubuntu but not Haiku and FreeDos. I downloaded acer.tar file. I updated grub on MBR with grub-customizer. I uploaded screenshot here. How to fix this? What can I do? Thanks.

My grub.cfg file

This has been covered in this issue #33. Let me know if you will need help. Currently I won't add icons for this OS, because it's a niche and it would be a waste of resources. You can create your own icons and copy it to icons folder where you have GRUB theme installed

Thank you. I added --class option in menuentry then It solved.
