Diskless starting method and device, terminal equipment and storage medium

The embodiment of the invention provides a diskless starting method and device, terminal equipment and a storage medium. The method comprises the following steps: mapping a shared memory based on PCIE NTB set on a host side to daughter card equipment through the NTB; at least copying partition information and a system file in the diskless boot mirror image file stored in the shared memory to a Ramdisk virtual disk on the daughter card device; and loading the boot file in the virtual disk, and starting the system according to the partition information and the system file. Therefore, the mirror image file is transmitted between the host side and the daughter card device through the shared memory based on the PCIE NTB, the daughter card side can directly achieve local card-free starting of the daughter card through the shared memory, network card configuration is not needed, and the application scene of card-free starting is improved. 本发明实施例提供的无盘启动方法、装置、终端设备和存储介质，将主机侧设置的基于PCIE NTB的共享内存通过NTB映射到子卡设备上；至少将共享内存中存储的无盘
