Help with GDT in bootloader

Post by icr09 »

Hi, I'm developing a bootloader for the i386 architecture from scratch and need some help with the transition from real mode (16-bit) to protected mode (32-bit)—specifically regarding the GDT, as I haven't been able to find resources explaining how to set it up. Could someone help me with a tutorial or teach me how to do it?
low overall standard :twisted:

Have you read the Intel Programmer’s manuals?
