AMOS 0.4.0 Released

[spacedsteve]

Hi all, I've put up the latest (long overdue) build of AMOS.

Get the source code : http://amos.harmonysecurity.com/files/amos-src-0.4.0.zip
Get the binaries: http://amos.harmonysecurity.com/files/amos-bin-0.4.0.zip

The main features are:
* Finished Memory manager subsystem with physical memory manager, virtual memory manager with paging, DMA, and a heap memory manager.
* File system subsystem with a semi implemented FAT file system driver (supports file opening, reading, directory traversal and listing). A device file system for accessing IO devices and a virtual file system to provide access to these underlying file systems.
* IO subsystem with an IO controller layer to marshell communications to IO device drivers (from the device file system), and default device drivers for the keyboard, virtual consoles and a semi compleated floppy driver (no write support yet).
* A bare bones process manager subsystem with a simple round robin scheduler with preemptive task switching and some simple routines for creating a process.

A productive 6 months of development I think, all comments welcome, cheers

Looks to boot fine in virtual pc, are there some commands you want us to try?

[spacedsteve]

no commands yet (next release plans to have an operational shell) but thanks. The current prompt on virtual console 1 is just to test getting in keyboard input.

I'd appreciate the virtual machine specs you have it running on though cheers thanks for trying it.

This OS is looking very nice. I like what you're doing with it.
Nice job.

Boots fine. I don't like the red background, but that's just me.

Otherwise, reminds me of my own os at the very first stages.

Hey, nice job.

Got the binaries. seem to run fine, although you entirely enabled for windows users =P.

*NIX users: you will need to do the following to get this OS working with bochs:

edit the bochsrc.bxrc:
* remove the "display_library: win32, options="legacyF12" # use F12 to toggle mouse" line, or comment it, using # at the start.
* change from \ to / here:

Code: Select all

romimage: file=$BXSHARE\BIOS-bochs-latest, address=0xf0000
vgaromimage: file=$BXSHARE\VGABIOS-lgpl-latest

rename AMOS.IMA file into amos.ima

I was just wondering why there is a text file, that you cannot read, eh?

also, like commented above - the red background colour scared me at the first boot, thought happened something bad but didn't.
also, let grub wait a second or two - people wnt to see the boot options =)

thanks for the *nix advice I'll try to accomidate non windose users better in future releases.

Ya the red background is a bit of a eye sore the next version has a classy looking white text on black background combo, very origional but looks way better ...the console numbers are displayed in red though

Im gona release 0.5.0 this week hopefully, it has the full multitasking subsystem with user mode process spawning and interactive shells
