[kwlug-disc] imac4,1 help

[Ron Singh]

Not sure if you are using a 32-bit or 64-bit cut of Ubuntu, but I ran into
a similar issue 2 years back on a older Toshiba Core Duo laptop and using
Mint 18.2 32-bit, and requiring me to turn on the "force-pae" flag in the
bootloader was the ticket to success in installing Mint Xfce 32-Bit (with
PAE-forced) on that old thing. Worked a treat. I wonder if it would word in
your case?

Oh yeah, I did stick with Legacy BIOS on that Toshiba, cannot recall if it
even had EFI.

Thanks,

Ron Singh
