>Description:
I am trying to use SYSLINUX to load *.iso
Actually I format and install to USB key syslinux
I copy memdisk to root of USB key
I unpack content to root of USB key
When I boot from USB I get SYSLINUX loaded
then I do:
memdisk initrd/boot/boot
I get invalid label
so I
da(0,a)
and I get registry dump in loop
