2025-07-25	Add VGA text mode driver	Carlos Maiolino
	Add driver to deal with VGA text mode. Also adds a simple vprintl function while I don't implement a print library. Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-25	Add string libraries	Carlos Maiolino
	Add a couple string lib functions to start with video text development. Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-21	Fix boot.bin build	Carlos Maiolino
	Previous patch TARGET variable definition got removed. I forgot to update its users.... Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-20	Tidy up Makefile	Carlos Maiolino
	Remove some duplicate code by creating a few variables Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-20	Add kernel.c	Carlos Maiolino
	Create the kernel.c file and its initial start_kernel(), and jump to it from the ASM. Also setup the build system to actually build it Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-20	Force alignment of kerne code.	Carlos Maiolino
	It should be aligned to 16-bits IIRC, forcing the kernel.asm to be alined to a 512 byte boundary should suffice Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-20	Add os.bin to makefile	Carlos Maiolino
	Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Add small ATA driver to load kernel	Carlos Maiolino
	Write ata_lba_read routine to load 100 disk sectors from the disk into memory address 0x00100000 (1MiB). Once the data is loaded, jump to that Address Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Start writing the kernel and add a linker script	Carlos Maiolino
	Move the code unders [BITS 32] label to its own file to be loaded as a kernel by the boot loader. Add a linker script to link the bootloader and the kernel in a single binary file. Add a build script to make it easier to use the cross compiler Update the Makefile to build everything and pack it into the os.bin Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Add build script	Carlos Maiolino
	Add a small script to use the cross compiler (from my machine), to build the kernel Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Enable A20 line	Carlos Maiolino
	Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Restructure project folder	Carlos Maiolino
	Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Setup GDT and load protected mode	Carlos Maiolino
	Create a GDT table and use it to switch CPU into protected mode. This also gets rid of the print routines. Giving we won't have access to the BIOS interrupts once we switch the CPU to protected mode, they are pointless. Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Prepare for enabling protected mode	Carlos Maiolino
	Clean up all testing/playground code to prepare the bootloader to enable protected mode. Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Add gitignore	Carlos Maiolino
	Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Remove interrupt table	Carlos Maiolino
	Remove interrupt table setup and testing, IRQs will be added later on an interrupt descriptor table. For some reason once the exception is handled, the disk read fails, so just remove it for now Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Initial commit	Carlos Maiolino
	Add a bootloader and a hello message. Signed-off-by: Carlos Maiolino <[email protected]>
