The primary boot is implemented in the BIOS ROM on the\r\n system board, and BIOS extensions in ROMs on peripheral\r\n boards. It is distinguished by its ability to control the\r\n installed peripheral devices and to provide I/O services\r\n through software interrupts. It begins the booting process\r\n by loading the first physical sector from a floppy disk,\r\n hard disk, or CD-ROM, or, if supported by the system or net-\r\n work adapter BIOS, by reading a bootstrap program from a\r\n network boot server. The primary boot is implemented in x86\r\n real-mode code.\n\n[ 本帖最后由 nus 于 2006-4-12 18:31 编辑 ] |
