Floppy & CD Tools:
Useful programs or utilities that fit on a single 3.5-inch floppy disk or
- MEMTEST-86 - Memory test program for x86 computers. Now included on many Linux installation CDs, so you may already have it.

- GRML - My current favorite Linux rescue CD.
- RIP - (R)escue (I)s (P)ossible, another Linux rescue CD that may work better on some hardware.

administrator really needs this tool.
