crowOS

4 November 2006 - 0.0.1

• The kernel now exists in virtual space (at 3GB + 1MB)
• The hardware memory manager, based on a stack, is working (might change it to a bitmap later, dunno right now..)
• Started playing with paging, so far so good.

To do:

• Write a pager than, at first stage, handles allocation of pages and such.
• More cleaning-up of the code
• ..and even more comments

17 June 2006 - 0.0.1

• Reprogrammed master IRQ to INT32 (0x20) and slave to INT40 (0x28)
• System timer working
• Prints a nice message once every second, yey!
• New screenshot of this, of course

So, next?

• Restructure the code, move the code around in the files etc
• Comments!
• Memory..

13 June 2006 - 0.0.1

• Project finally approved by the SF staff!
• The currently avaiable source (and more small things) added to subversion
• So, what can the OS do at this time?
• Bootup (with the help of GRUB)
• A basic printf, with support for printing integers (along with some other smaller things, like tab, LF etc)
• A new GDT
• The all-mighty IDT

..and what's up next?

Well.. Reprogramming the PIC and fixing some IRQ, maybe get some sort of keyboard-input. Probably virtual memory after that, but who knows really...
