View Full Version : UEFI: Meaning of efibootmgr strings 0x800,0x64000 after partition unique GUUID

17th November 2017, 06:14 AM
In efibootmgr -v I can see the EFI System Partition's unique GUID

Boot0000* CentOS HD(1,GPT,3b91d3af-b6fd-4a1d-94ed-aff5bca8c18c,0x800,0x64000)/File(\EFI\CENTOS\SHIM.EFI)

where 3b91d3af-b6fd-4a1d-94ed-aff5bca8c18c is the unique GUID from sgdisk.

What does the second part "...,0x800,0x64000" refer to?

Curious about this.
