+## Interrupt Descriptor Table
+This will be in a fixed memory location, this will contain pointers to the interupt function. Once an interupt is entered, all interupts are turned off.
+
+    IDT[0]          Divide-by-zero exception
+    IDT[1]          Hardware error (NMI)
+    IDT[2]          Overflow
+    IDT[3]          Invalid Opcode
+    IDT[4]          General-protection fault
+    IDT[5]          TLB miss
+    IDT[6]          Software interrupt (reserved for OS)
+    IDT[7-31]       Platform interrupts (PIC, hard drive, keyboard, etc.)
+
+    IDTMSK[0-31]    Interupt mask, when interupt is entered the mask bit for the coorisponding interupt will be disabled.
+                    The software is responsible for renabling the mask bit
+
+You get 32 :)
+Also, I was think of making the OS handle TLP misses

+
+## Page Directory
+
+The page directory contains 1024 page tables that have 1024 entries.
+
+^ Stupid question: Do we need a page directory? Also I have a very limited size for cache, idt, tlb, etc. Plan on having around 100 Kbits
+
+### Page table layout
+
+    PT[0]           Present
+    PT[1]           R/W
+    PT[2]           User-mode
+    PT[3-4]         RESERVED
+    PT[5]           Accessed
+    PT[6-7]         RESERVED
+    PT[8-31]        Physical address of page table (XX * 2^16 + XXXX)
+
+        *This is still WIP but I wanted to get your input on the layout. I also have
+        the jank memory offset that will more than likely change.*
