Running os with different BIOS(for example OVMF.fd, which is UEFI/BIOS):

make run BIOS=$(find /usr/share -name OVMF_CODE.fd)

Note, that THUNDERSTORM aims to be BIOS independent, but it is much better in qemu to run it with UEFI BIOS, since it is better supported.

NOTE: to see full list of TODOs please run grep -r -n TODO\ : in target folder

• ACPI support
• Power management
• PIC management
• local and IO APIC initialization \ management
• basic POSIX system calls
• add modules support
• Extended fs support (module)
• ISO 9660 support (module)
