I did it at the boot screen, I pressed f2 then typed
It started to boot but then complained about not being about to find the slacko.sfs file.
I guess it didn't work because of my crashed hard drive? It takes forever to search for puppy files, I assume it's searching through that mess when it doesn't need to. I would like to get it to stop doing that also, it takes like 10 minutes to boot because it hangs at that step for so long.
I ought to just take the drive out.
