Hi,

  http://t2sde.org/packages/syslinux

lists both variations of the isohybrid program as "Installed files":
  usr/bin/isohybrid
  usr/bin/isohybrid.pl

Only the former is capable of adding an EFI System Partition image.
The .pl script is older and cares only for the BIOS MBR code and a
simple partition table.


It has to be stressed that the T2 installation ISOs are not suitable
for the SYSLINUX isohybrid programs, because those ISOs have a GRUB
EL Torito boot image for BIOS booting. The isohybrid MBR would not
work with that boot image, but does officially only with the SYSLINUX
ISOLINUX image of the same SYSLINUX version as the isohybrid program.
(In practice the versions stayed compatible since years.)

With the recent ISOs like t2-minimal-musl-x86-64-r47636.iso, it is
not necessary to postprocess them in order to make them bootable from
USB stick. They have a GRUB MBR for BIOS.
It will be necessary to set the firmware to BIOS legacy mode, because
there is no EFI System Partition currently.


Have a nice day :)

Thomas
