当计算机启动时,该顾问办公室被装满时,该顾问办公室如何知道硬件信息,是否有奥教或boot方案从生物中获取信息?
The motherboard firmware (also called BIOS, ACPI interface or EFI) allows the OS to find out the physical mapping of RAM and ROM in the system.
For example, this is the output of a booting Linux:
[ 0.000000] BIOS-provided physical RAM map:
[ 0.000000] BIOS-e820: 0000000000000000 - 0000000000098c00 (usable)
[ 0.000000] BIOS-e820: 0000000000098c00 - 00000000000a0000 (reserved)
[ 0.000000] BIOS-e820: 00000000000e6000 - 0000000000100000 (reserved)
[ 0.000000] BIOS-e820: 0000000000100000 - 00000000bfea0000 (usable)
[ 0.000000] BIOS-e820: 00000000bfeae000 - 00000000bfeb0000 type 9
[ 0.000000] BIOS-e820: 00000000bfeb0000 - 00000000bfec0000 (ACPI data)
[ 0.000000] BIOS-e820: 00000000bfec0000 - 00000000bfef0000 (ACPI NVS)
[ 0.000000] BIOS-e820: 00000000bfef0000 - 00000000c0000000 (reserved)
[ 0.000000] BIOS-e820: 00000000ffc00000 - 0000000100000000 (reserved)
[ 0.000000] BIOS-e820: 0000000100000000 - 0000000c40000000 (usable)

A UEFI-based OS would typically get the physical memory map using the GetMemoryMap() interface.
For security reasons, it is desirable to check the integrity of code before execution, avoiding tampered software by an attacker. So, my question is How to sign executable code and run only trusted ...
