technical field
[0001] The present invention relates to the technical field of volume managers, in particular to a hard disk backboard lighting method, system and storage medium at the POST stage. Background technique
[0002] The current method of lighting the hard disk backplane in the POST stage is as follows. In the PEI stage, the BIOS sets the VMD to be on or off, and then enters the DXE stage to load the VMD driver. Therefore, there is an idle time after setting the VMD to the on state and before the VMD driver is loaded. ; During this idle time, the VMD driver has not been loaded yet, and the BIOS has sent the command that the VMD is open to the BMC, and sent to the CPLD through the BMC, and handed over the control of the backplane light to the CPLD; The disadvantage is that during the idle time, the CPLD has the problem of controlling the hard disk backplane to perform abnormal lighting.
