COMPUTER SYSTEM AND BOOT METHOD THEREOF

摘要

The disclosure provides a computer system and a boot method thereof performing steps of: establishing an order of interrupt vectors for an interruption according to an order of BBS tables of hardware peripherals; preserving empty spaces in a first address space of a memory when the hardware peripherals are being initialized; inserting the BBS tables into the empty spaces if the initialized hardware peripherals are first hardware peripherals, or inserting the BBS tables into the first address space except the empty spaces if the initialized hardware peripherals are not the first hardware peripherals; disabling the hardware peripherals except a second hardware peripheral; and rebooting the computer system to activate the remote operating system under a preboot execution environment via one of the first hardware peripherals after the second hardware peripheral boots the preboot execution environment to install a remote operating system into the one of the first hardware peripherals.

主权项

1. A boot method for a computer system which comprises a plurality of hardware peripherals each of which provides a basic input output system (BIOS) boot specification (BBS) table, comprising:
establishing an order of interrupt vectors for an interruption according to an order of the BBS tables of the hardware peripherals by the computer system when the computer system performs a power-on self-test of a BIOS; preserving a plurality of empty spaces in a first address space of a memory in the computer system when the hardware peripherals are being initialized, wherein the empty spaces are serial or not serial; inserting the BBS tables into the empty spaces according to a specific order when the initialized hardware peripherals are a plurality of first hardware peripherals, and inserting the BBS tables into the first address space except the empty spaces sequentially when the initialized hardware peripherals are not the first hardware peripherals, to sort the BBS tables according to a relative serial order; enabling a second hardware peripheral of the hardware peripherals and disabling the other hardware peripherals in a setup interface of the BIOS by the BIOS; booting a preboot execution environment via the second hardware peripheral to selectively install a remote operating system into one of the first hardware peripherals; rebooting the computer system after the remote operating system is installed in to the one of the first hardware peripherals; and booting the remote operating system under the preboot execution environment via the first hardware peripheral, which has installed with the remote operating system, when the second hardware peripheral boots the preboot execution environment.
