Bootable CD with Grub

without comments

Last week, I decided to boot Ace using CD image rather than floppy image because booting was slow when floppy image is used in bochs.

To create bootable cd with grub, stage2_eltorito should compiled from the grub source. The mkisofs is also needed to create the image. contains windows cygwin port of the cdrtools which contains mkisofs.

mkdir -p $ACE_ROOT/img/iso/boot/grub
cp $ACE_ROOT/img/boot/grub/stage2_eltorito $ACE_ROOT/img/iso/boot/grub
cp $ACE_ROOT/img/boot/grub/menu.lst $ACE_ROOT/img/iso/boot/grub
cp $ACE_ROOT/obj/kernel.sys $ACE_ROOT/img/iso/

mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot -boot-load-size 4 -boot-info-table -o $ACE_ROOT/img/bootcd.iso $ACE_ROOT/img/iso

This image can be written to a CD using any CD burning software.
