The operating system boot process is as follows:1. the BIOS reads the MBR to 0000: 7c00 and submits the execution permission to the MBR.2. MBR identifies partitions and reads dbr0000 with boot permission: 7c003 DBR: locate ntldr and read ntldr into memory at. ntldr is 32-bit and loaded into the kernel. The following is the code analysis in step 1 of the
The size of the MFC control varies with the size of the form.
