Test

Please note that 五OS won't run on 32bit systems anymore. 64bit or nothing!

Run with QEmu (for example) :

qemu-system-x86_64 -vga std -serial stdio -net nic,model=rtl8139 -net user -k fr mini.bin

If you don't use -vga std, the system won't be able to find a valid graphic card, and will fallback to VESA drivers (which are slower because of BIOS emulation)

What can I do with the image ?

The following interesting commands exists in the sample shell application.

• modp <module> Load a module in the kernel. Try for example: modp network/log to load the auto-logging module (will send all log messages to broadcast UDP port 1337). You can also load misc/helloworld for some C++ examples
• lsmod List loaded modules
• help Shows help
• ls
• cd <directory>
• cat <file>

Hard disk Data

You can extract the parition-space (ext2), and mount it on linux. Once you mounted it, you can edit it, umount it and write it back to the image.

Note: Mounting anything usually requires root privileges.

Extract and mount

dd if=mini.bin of=disk.img bs=512 skip=64k
mkdir disk
mount -o loop disk.img disk

Umount and pack back

umount disk
dd if=disk.img of=mini.bin bs=512 seek=64k
rm -rf disk.img disk

Recompile a new test.elf

Yes, you can now run your own applications using the Go-OS kernel ! Just replace test.elf inside the disk image by your own home-compiled application, and it'll work.

You will need the 五SDK (System SDK).

Sample code available from The first Go-OS external C program.
