As legacy BIOS isn't as straightforward to develop using a modern
system, modern emulators/VMs and virtual machine firmware, it was
decided to start work on an UEFI version of the Nightloader.
This commit leaves the not-yet boot-capable, but as far as it's
there already assembling and working legacy BIOS code behind for
later work on this edition.
Because the calculation of the byte offset within the framebuffer was
wrong, the framebuffer could only be written to on the first line.
That is now fixed.
The function which is added with this commit writes a caller-supplied
hexadecimal string of a caller-supplied length to the display, nibble
by nibble, leaving the background black and making the text white.
This commit adds the well known primitive memory functions:
- Copy Memory
- Compare Memory for being equal
- Set Memory to a value
It also adds a math utility file at the according location.
