- Added boot device info parsing to the kernel - Added a pointer in the kernel to our pre-kernel BootInfo structure - Created a layout for the FAT driver - Created a layout for the virtual filesystem - Separated IDE driver from the basic atapio driver. This will ensure we are not using one or the other - The create_harddrive shell script will now actually build a harddrive image of the kernel - The virtual filesystem initializes and creates a filesystem structure for every FAT16 partition in the master boot record
