Author: gjb Date: Thu Oct 15 17:12:58 2020 New Revision: 366732 URL: https://svnweb.freebsd.org/changeset/base/366732 Log: Increase the amd64 ISO ESP file size from 800KB to 1024KB. At some poing over the last week, the bootx64.efi file has grown past the 800KB threshold, resulting in being unable to copy it to the EFI/BOOT directory. # stat -f %z efiboot.znWo7m 819200 # stat -f %z stand-test.PIEugN/EFI/BOOT/bootx64.efi 842752 The comment in the script that creates the ISOs suggests that 800KB is the maximum allowed for the boot code, however I was able to boot an ISO with a 1024KB boot partition. Additionally, I verified against an ISO from OtherOS, where the boot EFI partition is 2.4MB.
