my dear friends and pundits (such as Wonko, Wimb, Alacrán and who more, who else and who not),
remember us all quibbling as to whether the innovations on g4d .45 (ahci and nvme) could be "transferred" to g4d .46 as well? well, I had a try copying the first line of the new menu.lst, applying it to the old menu.lst and running it all on grldr from g4d .46. well, I had no issue and it ran normally.
