This project hasn't been updated in a while, but I still imagine it in my head as simply being on hold. I lost some steam when I discovered my Bochs-based debugging couldn't handle the transition between 32-bit and 64-bit code and after having trouble implementing DMA for second-stage loading.
When life finds time, I expect to get back into this, but if you had any good resources for debugging this sort of low-level bootloader code, including 64-bit support, I'd like to hear about it.
./configure
makeThis will create a file called build/os.img which you can use to launch a VM.
