1) wat is the diff between first two options - i can see that the kernal and initrd file were diff but what r the other diff and wat is the need of two options?
I have been using suse for 3 years. I booted suse once and it worked. Otherwise I have never used it.
2) wat is memory tester for?
If you boot into the memory tester it will slowly work its way through your memory testing it for bad memory. I have never had any use for this function.
Whenever I do a SuSE install I delete the suse kernel and memory tester as a waste of space and take them out of the LILO screen as a waste of time.
