What does your OS look like? (Screen Shots..)

[SoUrcerer]

New KolibriOS cool stuff: PDF viewer and PlayStation emulator. More than 200 fixes for last 2 months, and now we're preparing for new stable release. Bug-tracker is available now too We hope to add some CSS and JavaScript to our Web Browser soon.

This is...stunning, nothing short of it, that is all :O

A JS engine in ASM, Good Luck!

A JS engine in ASM, Good Luck!

Whats so special and hard about a JS engine? You sound as if it's impossible when it's just another "compiler" written in ASM.

[Love4Boobies]

A JavaScript implementation written in assembly says two things: experience and great stupidity (the two are not mutually exclusive!).

[ACcurrent]

There are not many JS engines. We do not even have "tinyJS" like have TinyCC and TinyPY and TinyVM (JAVA). Those that do exist are huge in size and obfuscated. Developing a JS engine in ASM would be a challenge particularly with everyone writing bad CSS/HTML/JS.

[Love4Boobies]

My point is that a smart developer will make his/her life easier, not more complicated. You can eat steak with a spoon---just because it's a bigger challenge doesn't mean it's intelligent.

Hey, who said that JS engine is written in assembly? It's just C We're weird, but not very stupid. Btw, JS engine is ready, and supports JavaScript 1.5. You can check it if you want, but I think it's better to wait web browser another month or two.

multitasking and a VFS interface, I think I will try to start loading drivers! I'm pretty stoked

That's quite a lot of work. Anticipating future images

Thanks, although I'm not sure how much more I'll be posting. I was hoping to whip some quick driver loading code (this is a complete rewrite of an old kernel attempt, so I already know the basics), but haven't been able to, yet, and I'm leaving for school on Saturday. It's a military academy, so that means there isn't going to be much messing around, and I probably won't have my computer for a while... :/

edit:

I did get some more work done! Here's my newest screenshot. I've got driver loading (elf32 objects files, runtime linking) working, and I've written a little parser so I can just add module load calls to a file called /etc/modules.conf and the kernel will automagically load them Oh, I also got syscalls working. I haven't written all the syscalls yet, but the basic ones like open,close,read,yield, etc. are done. (the /etc/modules.conf was written using the open,close,read syscalls, actually). I've got a devfs driver written, so I can now write drivers for devices (first will probably be a serial IO driver, so I can have a working console without having to screw with the keyboard IO, at the moment )

Here is the format of the modules.conf:

Code: Select all

# this file should be filled with module(...) statements
# each statement should specify the path to a module 
# to be loaded at boot time. You should always add to the
# end of the list unless  you know what you are doing!
# 
# Also, after the last ')' on a module line, the parser
# ignores everything, so you can safely put comments without
# '#'s, but that doesn't look nice, now does it ;)

module(/bin/devfs.ko) 

It's incredibly simple, but does the trick, and even has basic syntax checking (just gives "error" and line number).

Nothing much to see, just Blacklight OS hooked up to PuTTY via a virtual null-modem cable.

Only characters after "ivt: interrupt_set_gate 00h 06h " are displayed because the kernel hooks int 10h/AH=0Eh so that all output via that function is dumped to the serial port. Currently, this is a compile-time kernel option. However, I'd like to make it an optional driver that does the necessary hooking of both int 10h and the kernel's keyboard stuff (technical term, I know), and that will be my next step after verifying that my terrible driver interface works.

My OS (based on GeekOS, in case you wondered):

[Mano]

This is my OS. The shell is listing the files in a directory, and showing what processes are running!


It's a VERY modest project compared to what I've seen around on this forum, but still, I'm very happy with it.

I have my drivers executing as server outside the kernel, and they communicate with other processes by passing messages. I support statically linked ELF executables. I have simplified implementations of the ISO9660 and FAT file systems, and an IDE PIO MODE driver (maybe one day I'll code something more appropriate).

Anyway, none of this would be possible without this community. I didn't even need to ask many questions, most of my doubts so far were asked, and aswered by the forums/wiki and of course other sites/articles/books I read. Thanks guys.

It's all old, but I have an album showing the development of my UI through the months.

Hello! I've looked at the site for years, but not really said anything until now. This is my first post ever!

My OS is not for an x86; it's for the 6502, and while I didn't write a whole lot to it, I thought I would post the panic test screenshots; one is from a C64 emulator, the other is from Daryl Rictor's 65C02 simulator. I'm a very small amount of code away from supporting the NES PPU as well.





I'm hoping to start coding an x86 OS soon, but this is what I've spent little bits of free time on since about November 2004.
