Hi,
instead of creating a new full 64 iso, i have extacted the provided rootfs.gz, i have extracted it, installed a new kernel ( from http://mirror1.slitaz.org/packages/next64/ ( kernel, kernel-efi, kernel-nfs, kernel-nfsd ) and i added it to syslinux
LABEL register
MENU LABEL Register as Pulse client
KERNEL ../davos/bzImage64
APPEND boot=live config noswap edd=on nomodeset vga=788 davos_action=REGISTER dump_path=inventories timereboot=2 tftp_ip=192.168.0.12
INITRD ../davos/rootfs.gz
it boots well on legacy but does not on UEFI ( if freezes after loading ../davos/rootfs.gz ).
Do i need to do something more ?
thanks for your help
