The invention provides a PXE network card initialization method and device compatible with 64-bit addressing and a medium, and relates to the technical field of network card initialization, and the method comprises the steps: discovering a network card device; reading a PCI configuration space of the network card equipment, obtaining information of an extended ROM base address register, and mapping a network card Option ROM to a memory shadow region; when the access of the memory mapping input and output mode fails, the initialization code performs read-write operation on the hardware register through a self-defined capability structure in a PCI configuration space of the network card equipment; based on the successfully accessed hardware register, network card hardware initialization is completed, and a PXE protocol stack structural body is established in a memory; registering system firmware as PXE starting equipment, and entering a protocol interaction stage with a PXE server; according to the invention, smooth development of a subsequent network boot flow is guaranteed, and the deployment success rate and the system stability in a large-scale batch installation scene are improved.

Disclosed are a server boot and operation method and apparatus, a server, and a storage medium. The server boot and operation method includes: during a power-on self-test (POST) process of a server, loading an Option ROM of each target peripheral device according to a peripheral device loading sequence and by using a target configuration space; in response to detecting that the target configuration space is insufficient, detecting remaining spaces of other modules in a preset address space; and in response to determining that the remaining spaces meet a required space corresponding to the target configuration space, reallocating a preset address space to ensure that the reallocated configuration space for the peripheral device loading module is greater than or equal to a sum of the target configuration space and the required space.

The invention provides a method for generating a configuration interface. The method for generating the configuration interface comprises the following steps of: loading a UEFI Option ROM (Read Only Memory) driver of external equipment through a UEFI of main equipment, wherein the UEFI Option ROM driver is generated according to the UEFI driver and a configuration interface file; and dynamically analyzing a configuration interface file in the UEFI Option ROM driver through a file analyzer in the UEFI Option ROM driver, and creating a configuration interface option of a UEFI setting interface of the main equipment according to an analysis result. According to the configuration interface generation method provided by the invention, a user can flexibly configure and manage the configuration interface of the external equipment.

A method for generating configuration interfaces is provided. The method comprises loading a UEFI Option ROM driver of an external device through a UEFI of a host device, where the UEFI Option ROM driver is generated based on a UEFI driver and a configuration interface file; dynamically parsing the configuration interface file of the UEFI Option ROM driver using a file parser within the UEFI Option ROM driver to obtain a parsing result, and creating configuration interface options for a UEFI setup menu of the host device based on the parsing result. By utilizing the above method, users can flexibly configure and manage the interfaces of the external device.

The application discloses a kind of server loading PCIE card Option ROM fault-tolerant mechanism control method, device and medium, method includes: entering PCI bus to the enumeration detection link of PCIE card to be measured;If the configuration space information of current enumeration PCIE card is different from the content of PCIE card link table, the Option Rom program of current PCIE card is loaded into memory, and generates EFI_IMAGE_HANDLE information, records the configuration space information of current PCIE card Option ROM program in memory by EFI_IMAGE_HANDLE information;According to the configuration space information of current enumeration PCIE card, new node is constructed and is inserted into PCIE card link table, and PCIE card hardware initialization is executed;Check the execution state of the Option Rom program of current PCIE card, if the Option Rom program of PCIE card is normally executed, delete the relevant information of current PCIE card stored in nonvolatile storage area, skip the detection of current PCIE card, and continue to enumerate next PCIE card to be measured.The application effectively avoids repeated loading, can quickly skip abnormal PCIE card, and record relevant log information, improve the overall performance and reliability of server.

This application discloses a data migration method, storage medium, and computer program product. The method is applied to a first device, which has a first software process. The method includes: calling a first PCI virtual function device (PCI device) through the first software process; obtaining relevant information about first information of a first virtual machine through the first PCI device; the first PCI device represents the Option ROM in a first DPU of the first device; and sending second information to a second software process on a second device through the first software process, so that the second software process migrates the first information from the first virtual machine to the second virtual machine based on the relevant information of the first information contained in the second information; wherein the second information represents data migration instruction information, the first virtual machine runs on the first device, and the second virtual machine runs on the second device.

The application discloses a BIOS Option Rom Setup option network translation system and method. The application can solve the problem of providing Chinese translation for commercial PCIE peripherals. The translation system is loaded by BIOS, analyzes the peripheral board type, confirms whether the Option Rom has a Chinese language package through analysis and resolution, combines local translation with network translation, adds the translated result in the form of a language package to a new package, and UEFI BIOS automatically matches all supported languages for display. The application can display the Option Rom Chinese translation option on the BIOS interface, solves the problem that commercial board cards are not equipped with Chinese language packages, and improves the convenience of domestic users using commercial board cards. Meanwhile, the application is dynamic translation, and does not need BIOS manufacturers or other BIOS staff to extract, translate and preset Chinese language packages of commercial board cards in advance, thereby improving the local language automatic adaptation capability of the peripheral board card.
