I replaced Puppy-526 with Puppy-527 hoping that Firefox would work better.
It crashes at any given moment and really crashes when playing any videos.
The Grub menu still lists 526 even though the menu.lst file doesn`t have it!
I removed all of Grub`s backup menu.lst.xxxxx files, and it still shows 526 !!!
Must be another file that Grub is using instead of: /mnt/sda1/boot/grub/menu.lst
