Memtest86 is a thorough, stand-alone memory test for x86 architecture computers. BIOS based memory tests are a quick, cursory check and often miss many of the failures that are detected by Memtest86. This package installs a bootable image to /boot/memtest86.bin which is similar to the kernel images in the same directory. LILO users: Append this to your /etc/lilo.conf: image = /boot/memtest86.bin label = memtest86 Then run `/sbin/lilo` to update the boot loader. Don't forget to re-run `/sbin/lilo` if you upgrade this package. GRUB 2 users: Append something like this to your /etc/grub.d/40_custom: menuentry 'memtest86' { linux16 (hd0,1)/boot/memtest86.bin } Then run `grub-mkconfig -o /boot/grub/grub.cfg` to update the boot menu. GRUB Legacy users: Append something like this to your /boot/grub/menu.lst: title memtest86 kernel (hd0,0)/boot/memtest86.bin See /usr/doc/memtest86-$VERSION/README for more info.
