Method for loading PCIE Option Rom to UEFI BIOS

Abstract

The invention discloses a method for loading a PCIE Option Rom to a UEFI BIOS. The method comprises the steps that during PCI enumeration, PCIE equipment is detected; whether the PCIE equipment contains an Option Rom is checked; whether the Option Rom is of a UEFI type is checked; the UEFI Option Rom is copied into a memory; and the UEFI Option Rom copied into the memory is run. When a PCIE card is plugged into a server and the card comprises a traditional Option Rom, PCIE enumeration time can be shortened, and the more the number of cards, the more obvious the effect. Finally, the purpose ofquick start of the UEFI BIOS is achieved, and the highlight and competitiveness of a product are enhanced.

Description

technical field [0001] The invention belongs to computer software system technology, in particular to a method for UEFI BIOS loading PCIE Option Rom. Background technique [0002] There are two types of BIOS in the industry, namely traditional BIOS and UEFI BIOS. Also for the above two kinds of BIOS, there are two types of PCIE Option Rom, namely the traditional Option Rom and UEFI Option Rom. [0003] Although UEFI BIOS is replacing the traditional BIOS, because the PCIE peripherals must be compatible with the traditional BIOS, most of the PCIE cards on the market still only support the traditional Option Rom or are compatible with the new UEFI Option Rom. [0004] The existing technology was when UEFI was just emerging, for the sake of market compatibility, but with the development of BIOS, the traditional BIOS is gradually withdrawing from the market, and the new BIOS began to completely replace the traditional BIOS, so now in order to save memory and execute Speed, to ...

Problems solved by technology

[0003] Although UEFI BIOS is replacing the traditional BIOS, because the PCIE peripherals must be compatible with the traditional BIOS, most of the PCIE cards on the market still only support the traditional Option Rom or are compatible with the new UEFI Option Rom

[0004] The existing technology was when UEFI was just emerging, for the sake of market compatibility, but with the development of BIOS, the traditional BIOS is gradually withdrawing from the market, and the new BIOS began to completely replace the traditional BIOS, so now in order to save memory and execute Speed, to consider the problem of matching

[0005] The problem now is that only UEFI BIOS is used for the newly developed server, but when PCIE is enumerated, all the Option Rom on the PCIE card is copied to the memory, and no judgment is made on whether the current Option Rom matches the UEFI BIOS Moreover, there are many PCIE cards on the server, and some traditional Option Roms are very large, which will significantly prolong the time for PCIE enumeration. This phenomenon is especially obvious on low-configuration ARM platforms.
