Hi,
My 15 year old son has found an old 2011 iMac in the side of the road.
Long story short is that the processor probably works, but we think the
GPU is dead as we cannot get video out of the mini display port
connector, or the screen.
So, I would like to boot from a Debian live ISO with the following
kernel parameters (set in grub.cfg).
console=ttyUSB0,19200n8
Now, I can mount up the ISO in loop mode, and get into grub.cfg, but how
do I write this back to the ISO so that I can put in on a USB flash drive?
Thanks!
Paul.
Hello,
I don't think you need to do that:
https://www.debian.org/releases/stable/amd64/ch05s01.en.html
Chapter 5.1.5. The Boot Screen
"[...]If you wish or need to add any boot parameters for either the
installer or the kernel, press Tab (BIOS boot), or e then down arrow
three times then end, to edit the “linux” line of the boot entry (UEFI
boot). This will bring the boot command for the selected menu entry and
allow you to edit it to suit your needs. Note that the keyboard layout
at this point is still QWERTY. The help screens (see below) list some
common possible options. Press Enter (BIOS boot) or F10 (UEFI boot) to
boot the installer with your options; pressing Esc will return you to
the boot menu and undo any changes you made.[...]
(you can use an Debian install media but I suppose a Debian live media
would propose the same way of entering parameters)
