[syslinux] Question on memdisk with UEFI boot.

[solarflow99]

Are you using memtest 6?  This is what I use and it works fine in bios and
efi mode, notice i'm not using the whole ISO.



*menuentry 'Memtest' {


                linux images/utils/memtest/memtest6.efi


                          } *
