Non-parity memory is cheaper, but memory errors cannot be directly detected. However, there are programs one can run if one suspects that he/she has a bad memory stick. One such program, memtest86+, provides a stand-alone memory testing program built to resemble a Linux kernel, so that Linuxboot loaders think it is a Linux kernel and will load it like one (the entire boot image is loaded, not just a single sector, as with "other").

The third "image" entry defines the stand-alone memtest86+ program. To run it, the user types "memtest86+" (without the quotes) at a LILO "boot:" prompt. This boot entry may be thought of as a special Linux kernel which is outside the normal cycle of "most recent" and "next-most recent". -- .''`. Stephen Powell <zlinux...@fastmail.com> : :' : `. `'` `-
