I made my own DOS implementation (Announce)

posted by samwdpckr, 23.03.2024, 20:32

Anyway, now the owner of the MCB changes when the realloc syscall is made, so modifying the internal structs is not necessary. I don't know if that works in FreeDOS, but because FreeDOS aims to be a 100% MS-DOS compatible operating system, it SHOULD work - if it doesn't, then it is a bug.

ST-DOS is not meant to be a clone of MS-DOS. Instead it is meant to be (mostly) compatible with the documented programming interface, so that it satisfies most already existing DOS programs and makes it easy to write new programs in such way that it works on both ST-DOS and FreeDOS. Many old CP/M syscalls are not supported, but I'll probably write a "compatibility TSR" that implements some syscalls that are currently not implemented in the kernel.

The main purpose of ST-DOS is to be as efficient 16-bit disk operating system as possible, and a software layer that provides basic I/O syscalls for accessing file systems and storage devices in Unix-like manner. If you need an MS-DOS clone, then you should just use FreeDOS.
