IndigoOS

This project is in it's infancy. There's a lot to clean up (bootloader), and this is for my own entertainment. I'll likely be working on it on and off, and only updating the branch after major steps forward.

##Questions and answers

Why are you already parsing APCI tables?

When I first started this project, it was intended to be a bare metal mandelbrotset, then an operating system. This way I could set up an enviornment and become comftorable with the x86 architecture. I was going to have a pretty simple multi-core SMP setup to acheive a higher speed. However, as I worked more and more, I realized that this plan was counter productive. The main reason for this is that I'd be doing a lot of "static" work (for lack of a better word). It would be too hard to modify an existing project into an operating system, due to all the code I'd need to discard.

Will you support UEFI?

Maybe some day. What I have so far of the bootloader was a lot of work, so I need to take a break on it for now.

##Cleaning list

• [] clean RSDP v1 vs v2+ ugly unison code
• [] clean static paging code if possible
• [] fallback to best compatable video mode if not found
• [] find out when and why checksum of binary vs debug binary stripped is occationally diffrent (maybe linker script?)

##debugging

• get debugging into into a seperate elf for GDB
• [] md5sum of striped binary is the same as one built without debugging info Almost always, there was one time when it wasn't. Can't seem to reproduce. Check linker sizes.

##bootloader

• make USB bootable as floppy
• [] make USB bootable as harddisk
• detect native resolution
• set VESA video to native resolution
• [] fallback to best compatable video mode if not found
• record video mode info for kernel
• setup temporary page tabels
• get memory map
• load sectors into 0x100000
• boot into kernel long mode

##kernel (listed in order of dependency) ###ACPI

• find, check, and parse RSDP
• find, check, and parse RSDT or XSDT
• static page mapping
• [] remap paging to higher/more available physical address
• [] remap kernel to higher virtual address
• [] re-create page tables to accomidate amount of ram in system without becoming too big
• [] dynamic page allocation

###multicpu

• [] boot cpus
• [] parse MDST
