A simple x86 firmware that can boot Linux. Usage:
fw_cfg based example:
$ qemu-kvm -bios bios.bin \
-kernel /boot/vmlinuz-4.0.3-300.fc22.x86_64 \
-serial mon:stdio -append 'console=ttyS0,115200,8n1'
cbfs-based example (pflash isn't the definitive interface though):
$ dd if=/dev/zero of=boot.bin bs=4096 count=1
$ cbfstool cbfs.rom create -s 8m -B boot.bin -m x86 -o 0x1000
$ cbfstool cbfs.rom add -f /boot/vmlinuz-4.0.3-300.fc22.x86_64 -n vmlinuz -t raw
$ echo 'console=ttyS0,115200,8n1' > cmdline
$ cbfstool cbfs.rom add -f cmdline -n cmdline -t raw
$ qemu-kvm -drive if=pflash,file=bios.bin,readonly=on \
-drive if=pflash,file=cbfs.rom,readonly=on \
-serial mon:stdio
TODO:
- ACPI tables
- SMBIOS tables
- Multiboot loading
