Hi:
Thanks for your replies. I referred to some examples in baselib, for
example,WriteMsr64.asm, WriteMsr64.nasm,
WriteMsr64.c and create Reboot.asm, Reboot.nasm, Reboot.c file in
MdePkg->Library->BaseLib-> Ia32. I also made some
corresponding Changes in BaseLib.inf and other files. And I did avoid to use
X64 arch. So my cmos.c source file in AppPkg is like
this:
#include<Library/BaseLib.h>
Void main()
{
Reboot();
}
But the compiled result is Reboot.lib(Reboot.obj):error LNK2001:
####\DEBUG\cmos.dll:fatal error LINK1120:1
The picture is the compiled result, and I wonder if I missed to create or
modify some files?
Thanks for helping !
Best Regards!

Also the BaseLib has a lot of C APIs that abstract a lot of common things you
use online assembly for. Not to mention that how to do inline assembly is not
standard in C.
