my simple OS
phase One:
- testing only in qemu
- simple real modus
- only Assembler (at moment NASM)
- simple output
- simple file input with write to disk file
our memory layout is real mode, we dont use segments
0x7c00 - 0x7dff boot sector 0x7e00 - 0x9dff kernel 8k Memory (thus kernel should not be bigger as 8kb)
0x0007FFFF is our upper segment stack
file is 1440 kB big 2880 512Byte sectors
Sector 0: bootloader Sector 1-16: kernel, 16 sectors -> 8kByte Sector 100-x: command file to execute
