Reverse-Engineering The AMD Secure Processor Inside The CPU August 18, 2024byMaya Posch10 Comments On an x86 system the BIOS is the first part of the system to become active along with the basic CPU core(s) functionality, or so things used to be until Intel introduced its Management Engine...
或者xor eax,eax。 - Peter Cordes 显示剩余5条评论 6 根据这个页面:StackExchange's Reverse Engineering,在x86-64架构中,mov edi, edi不是NOP指令。在x86-64架构中,它会将rdi寄存器的高32位清零。我认为这很重要,需要补充的回答。 - Jeach网页内容由stack overflow 提供, 点击上面的 可以查看英文原文, ...

PUSH指令会对ESP/RSP/SP寄存器的值进行减法运算,使之减去4(32位)或8(64位),然后将操作数写到上述寄存器里的指针所指向的内存中。 POP指令是PUSH的逆操作:他先从栈指针(Stack Pionter,上面三个寄存器之一)指向的内存中读取数据,用以备用(通常是写到其他寄存器里面),然后再将栈指针的数值加上4或8. 在分配栈...

I’m not going to do more reverse engineering. NOTE: Main memory is not initialized yet at this time. From here: The motherboard ensures that the instruction at the reset vector is a jump to the memory location mapped to the BIOS entry point. This jump implicitly clears the hidden base...
