Ich verstehe, will die Bedeutung von x86 Real-Mode-Einspeisepunkt in Linux-Kernel:Was .Byte start_of_setup-1f bedeutet in Linux-Kernel-Code
_start:
# Explicitly enter this as bytes, or the assembler
# tries to generate a 3-byte jump here, which causes
# everything else to push off to the wrong offset.
.byte 0xeb # short (2-byte) jump
.byte start_of_setup-1f
