NTDIOS - Network Disk Operating System

What is NTDIOS?

NTDIOS (Network Disk Operating System), Disk and network operating system. Like Windows, Linux, BeOs, MsDos, its purpose was to manage and process the fundamental functions of a microcomputer. NTDIOS was an operating system for AT Compatible under X86 compatible microprocessor. It was fully developed in assembler and compiled with NASM / TASM. When the kernel is finished, it hope to progress towards a port to C / C ++ and the like.

What does NTDIOS do?

What NTDIOS is doing today is little. NTDIOS is more or less at the stage of an MSDOS (apparently) not too finished but in 32 bit mode. This is why they are only in the ALPHA phase of the project.

Developments made

1. Bootstrap

The bootstrap is located on the 1st sector of the boot disk and is responsible for launching the primary kernel of NTDIOS. It contains information about the structure of the drive and the settings for encryption and locking the drive. Anti-virus Boot-Checksum technique.
