Your OS functions

inflater · Post by **inflater** » Sat Oct 28, 2006 8:35 am

Hi,
maybe this needs to move to other forum, but:

What version and functions does have your OS?

My PortixOS 0.4 has:

- Real mode
- Can run on ANY 8086 processor (and better) - but must have EGA (and better)
- Slovak language (sorry guys)
- Selection of processors (80286 and below / 80386 or better)
- very simple HW detection (CMOS,memory,graphics adapter,CPU)
- very simple command line (case sensitive); it can recognize a command and a parameter to that command
- ability to draw colored text windows (but still, UI is not written yet)
- APM 1.2 support (ATX boards)
- Slovak characters (ľ,š,č,ť,ž,ý,á,í,é,ď,ä,ô,ň)
- Real mode memory managment up to 4 GB for 80386 and later
- some basic "sound" trough the speaker (really crappy)
- IRQ handling, but can't use it - must study it first

- fits on a single floppy (kernel has 25 KB, UPX'ed 14 KB)
- has a web page (unfinished): http://www.portixos.tk
- Altough, it is a stable system (!) but less functions.

What must be fixed or added in next release(s):

- in this version 0.4: at least simple file managment (running EXEs)
- in version 0.5: PS/2 and comm handling (modems)
- in other versions: 800x600x16 GUI

And, what specifications have/will have your OS?

name: JouleOS
it's 32bit and only relys on 486 cpu optimizations
kernel is about 240kb(big cause I still dont have a linker script so I don't have bss)
very very basic multitasking and the OS and Console and such are not yet "thread-safe"
some very buggy fdd code that works about 1 out of every 3 times(lots of race conditions)
complete working console with backspace and caps and such(you can type help or list or test;tblah or whatever)
Com1 port support mostly working(works most of the time)
terminal to communicate via Com1
malloc and free and such
a few nifty working thigns in idt such as InstallInterruptHook()
some basic pc speaker stuff
it's event driven though the EventDrive thing is being completely rewritten
has multiple console support(their not hooked into threads and stuff yet though so not different keyboard stacks or anything..)
able to change standard VGA video modes without v8086(infact don't have v8086!)
have cpuid code(thanks to bryan_brynet)
and last but not least.. have the framework for application interrupts laid down

will eventually have...
Fat12 support
bug free fdd driver
bug free ps/2 mouse driver
my OS thread-safe
and a few other things...

meh probably overly drawn out but hey you said post OS function

oops.. have a website to http://JouleOS.galekus.com ... wonder why my website is no longer on my sig

edit2: now fixed...

Hi,

For my OS there's a "current version", and previous versions. The current version doesn't do much - I'm currently porting code from older versions.

Current Version

General design is a "modular micro-kernel", which is like a normal micro-kernel except the kernel itself (and the boot code) consists of seperate replaceable modules.

Minimum Requirements

- 80486 with FPU or better (single-CPU)
- Pentium or better (multi-CPU)
- 4 MB of RAM (allow a little more for NUMA, depending on how many domains)
- a keyboard and VGA, or a serial port (headless, see note)
- a floppy driver, or network card (diskless boot)

Note: For headless systems, a serial terminal is required for diagnosing boot problems and OS installation, but not for normal operation. A serial port is always required.

Current features:

- floppy boot
- network boot (PXE)
- supports headless systems
- supports boot scripts
- does memory detection
- incomplete CPU detection code (I'm working on it)

Previous Versions (all combined)

Features:

- multi-CPU support (including different CPUs in the same computer)
- hyper-threading support
- NUMA support
- 32-bit plain paging, "36-bit" (PAE) paging and 64 bit/long mode
- compressed boot image support
- PCI bus scan, ISA Plug & Play scan, generic ISA device detection
- floppy driver, serial port driver
- PS/2 keyboard driver (including "dual keyboard" setups)
- incomplete serial and PS/2 mouse support
- CLI
- text mode GUI
- scripting language (similar to BASIC)
- an Othello port (one I can't beat on it's highest level)
- generic video support (a boot menu to choose which video mode to use after boot, including SVGA via. VESA)
- (partially incomplete) internationisation, including time & date, daylight savings, international phone dialing prefixes, currency, simple strings (yes, no, OK, cancel, etc), number formats, etc.
- misc. stuff and things I forgot I did..

There's also a web site and some forums for the project.

Cheers,

Brendan

Solar OS
http://www.oby.ro/os/index.html

You can find the API reference here:
http://www.oby.ro/os/refer_api/os_refer_api.htm

The OS is:
-protected mode only
-realtime
-Advanced GUI with controls: buttons, checkbox,editbox,listbox, tree,listview, etc, multiple desktops
-advanced hardware drivers for network
-Ethernet, IP, DNS, ICMP, UDP protocolls
-applications, viewers: BMP, Text, PE, Hex
-file browse and API (Fat32)
-lately it can Load, Map, resolve imports and RUN PE files!

It might become capable or running simple Win32 and Linux applications ..soon

BlueIllusionOS:

Microkernel on iX86.
has: paging, virtual memory management, process/thread model, messaging/event interface ...
services: process manager, file system (ext2 read/write, iso9660), gui, network (ethernet, arp,ip,tcp,udp & some nic drivers), dhcpcd (service), user manager service, logger service ...

gui offers following features via library: button,checkbox,radiobutton,listbox,multiline text box,multiline text edit, single line edit, label, image, icon,scrollbar, menue, tabpages ... well and transparent windows. Transparent drawing will be implemented in the client library too, so the drawing operations can be given some alpha channel parameter.

There are some applications present - look here: www.distantvoices.org

stay safe.

Well first, since my OS is based on Borealis by Chris Giese, I'll list his features first:

32-Bit Protected mode OS
Can be booted from GRUB or Chris' own boot loader from dos
Multiple consoles (1 for each process)
User mode applications with their own libc (uses interrupts for some functions)
Kernel mode applications which have their libc symbols altered at load time to match the kernel's libc functions
Serial port IO
Task states (running, waiting, zombied)
A few games (tetris, 'ansi invaders')

And then I added my own features:

Better kernel symbol lookups
Non-blocking InterProcess Communication (Asynchronous IPC)
PS2 mouse driver
VGA graphics (320x200x8bit) driver
Daemon mode applications (all run on 1st console)
Different wait states, and a task priority/nice system
Console application (which talks to the VGA daemon to switch into vga mode)
System topography application (show processes, name, cpu usage, cpu time, overall cpu balance and usage)

I've since restarted my project due to it not working at all on VMWare, so it's slowly getting back to the above stage.
