Enabled paging and am getting page faults!

### The goal
Writing a hobby operating system to better understand the basic building blocks of any operating system.Initially I'd like for my 
operating system to be able to run bash.

________________________
### Operating System Technical specs/details
The operating system can print strings to the 
screen. The terminal/screen has scrolling so the latest messages are visible on the screen.

Added an otter logo! I think its so cute 2021-05-26 18:51:35 +00:00
Moving logo to png format gitea doesn't handle svg format, simplified screenshot inclusion in readme 2021-05-26 19:03:53 +00:00			`![Logo](images/BarinkOS.png)`
Adding logo properly to README, hopefully this way it show up in preview on gitea 2021-05-26 18:58:27 +00:00

Added emulator options, Added header for VBE driver, Added CPUID function, Added demodisk.img as drive 2021-07-22 21:14:58 +00:00			`![Interrupt handeling](screenshots/WIP_interruptHandling.png) \`
More work on interrupt handling, Started timer interrupt implementation, PIC remapped hopefully successfull 2021-05-16 14:53:14 +00:00			`W.I.P - Working on interrupt handling`

			`Multiboot information can be read by the kernel.`
End of the day cleanup. * Added symbol files to .gitignore * Improved text in #PG and #GP handlers * Added the printing of the multiboot structure address and the magic value * Added page fault screenshot to readme 2022-08-18 23:05:10 +00:00

Initial setup, Basic helloworld kernel from wiki.osdev.org bare bones 2021-05-02 16:02:00 +00:00
			`### The goal`
Basic block allocation for physical memory allocation. - 1 block = 4096 bytes : because this will make page fault handling possibly somewhat easier - 1 byte in the bitmap = 8 blocks of physical memory unsure if the allocation is perfect ... guess i'll find out some day if this is actually correct. The bitmap needs 16kb to keep track of 2gb of physical memory. Seems a decent percentage to me. 2022-02-26 19:44:16 +00:00			`Writing a hobby operating system to better understand the basic building blocks of any operating system.Initially I'd like for my`
