* - [ ] Update SMBIOS functions to support newer versions and actually use it.
|
||||
* - [ ] COW (Copy On Write) for the virtual memory. (https://en.wikipedia.org/wiki/Copy-on-write)
|
||||
* - [ ] Bootstrap should have a separate bss section + PHDR.
|

* - [ ] Reimplement the driver conflict detection.

* ISSUES:
|

* - [x] Kernel stack is smashed when an interrupt occurs. (this bug it occurs when an interrupt like IRQ1 or IRQ12 occurs)
