I was about to write the same thing when I remembered that he has 'plonked'
both of us. Someone else will have to tell this psychologist who
has "exercised my interest in computers maybe 20 years ago" that he's not

Heh, yeah I forgot about that. Could one of you non-plonkees quote this
so he'll see it (or remind the idiot directly)? Thanks.

And to think, I actually wasted a "please" in my request. Bummer.

I think my config of lilo has nothing to do with the problem, because
it has never changed since i first installed slack and before i could
boot with anything plugged in any usb "slot".
any way i'm pasting the lilo.conf file to make ideas clear for you and
others.

yes that's probably the origin of the problem

note that the framebuffer is not enabled in my kernel, i do never
enable it. I'm reminding that because s.o. said that this could be the
cause of the issue. But even that i think this is the cause of the
issue because i did never enabled it since i first configured my
custom kernel, this the same time as when i first installed slack
because no one of the suggested kernel was suitable for my laptop.

I'm not telling lilo to boot on my usbkey, I'm telling the bios to
check a usb port to boot on if it is bootable.

forget about lilo booting on the usb
