It turns out that my original copy of puppy was no good so I burnt another and this one boots up on my CF-28 and I have sound
I can run it in high resolution too. I'm quite chuffed with that. Puppy Linux will now be its main OS if everything goes to plan figures crossed... I installed it to the hard drive but made a mistake when I installed the grub boot loader so I've got to start again, hopefully I'll get lucky the second time. I was mainly just looking for a graphical desktop environment for this specific laptop for basic use.
This doesn't mean I've abandoned Tiny Core I have installed Tiny Core on another laptop as it does interest me and I hope to learn more about as I go along
