You have reached the homepage for KeyOS. Here's what I've got done so far:

• Bootloader (using GRUB)
• Clear screen function
• printf() with variable support
• Scrolling video buffer (a newline at the bottom of the screen pushes everything up one line)
• Detection of the CPU ID
• Enabling and remapping of the PIC
• Color support
• KernelStatus support

This is what I am currently working on:

• Enabling/configuring the GDT
• Enabling/configuring the IDT
• Enabling the keyboard
• A basic command shell that does nothing

The project was dropped months ago, and I've decided to revive it. Currently, the CVS code is the old KeyOS. When I have enough code to put into CVS, I will wipe out the old CVS and commit the new code.

You will be able to eventually download the nightly CVS tarball below. I try to only commit bootable, working code to CVS, so if you download this, it will most likely boot.

To compile this, you need to be running a kernel with loopback filesystem support. However, the CVS tarball soon will contain two binary images, which you can use even if you do not have loopback support.

1. su to root

2. Type 'make' in the kernel/ directory

3. Fire up bochs to boot from the c.img in the keyOS directory

4. Type 'kernel (hd0,0)/kernel' in GRUB

5. Type 'boot' in GRUB

6. Enjoy!

Note:  I have not tested this with real hardware, though I don't see why it shouldn't work.
It runs fine in Bochs though.


Enjoy!
