Bootloader that plays bad apple

• get frames from https://archive.org/details/bad_apple_is.7z and format using python code (run main.py)
• preformatted frames are included

HOW TO RUN IN VM

Make

nasm -f bin src/boot.asm -o os.bin

• will take a while to compile as every frame is also compiled

Run

qemu-system-x86_64 -device ide-hd,drive=dr,cyls=4,heads=16,secs=63 -drive if=none,id=dr,format=raw,file=os.bin

• qemu tends to lag so the fps won't be exact, however is fine on bare-metal

HOW TO RUN ON BARE-METAL

• requires legacy boot capable computer (tested with thinkpad e320)

Partition with Grub Menu

• create a partition and using dd to copy the .bin

• dd if=os.bin of=/dev/PARTITION WARNING: PARTITION DATA WILL BE OVERWRITTEN

• you will need to edit the source code with your partitions start CHS (see src/boot.asm), location of partition which can be found using: fdisk -x

• then add grub boot menu option by editing /boot/grub/grub.cfg

• the (DRIVE,PARTITION) can be found through grub command line ls , e.g. (hd0,msdos2)

menuentry 'CHOSEN_NAME' {
  set root=(DRIVE,PARTITION)
  chainloader +1
}

• reboot and select new grub entry

USB

• take an unformatted usb and dd the .bin to it dd if=os.bin of=/dev/USB

• reboot and select the usb in bios boot menu (some bioses not compatible with certain usb's) or chainload usb through grub command line

TO DO

• add sound
• rewrite python to directly build to binary
• improve frame speed
