Description
Desiros is a development project of a kernel. I use the GPL because it more independence to developers.
All participation is welcome, if you have any comments or suggestions on the current code,
please send email to desiros.dev@gmail.com .
What a Kernel?
In computing, the kernel is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components). Usually, as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources (especially processors and I/O devices) that application software must control to perform its function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls.

Details
Language: Desiros coded with C language and GNU assembly.
Bootloader: To load the kernel in memory is necessary to use a bootloader.
Desiros uses akernelloader as bootloader.
