Create a two-stage bootloader where Stage 1 loads Stage 2.

Requirements:

• Stage 2: print confirmation message, show it is running
• Load Stage 2 to memory address 0x7E00
• Use proper far jump to enter Stage 2
• Stage 2 should reinitialize segment registers
• Stage 2 should set up its own stack
• Both stages must have boot signatures where needed
• Include clear comments distinguishing Stage 1 and Stage 2
• Print drive number passed by BIOS

Test:

• Show Stage 1 running
• Show Stage 2 loaded
• Show Stage 2 confirmation message
