General requirements for a Linux rescue CD:
- Best with at least 2.6.18 kernel, support later SATA controllers
(e.g. JMICRON 36x only in 2.6.18)
- AHCI support
- Network support with newer network drivers
- Can load the whole CD into RAM
- Can install to USB key
- Optional upgradable kernel

• System Rescue CD
  Latest version 0.3.0 at 2006-12-20, size: 150M
  Kernel 2.6.18.5 patched, can load the whole CD into RAM ('docache' boot option), can install to USB key
  To boot system into RAM, require 320M RAM! (nofb docache noxdetect)
• R.I.P. Linux
  Latest version 1.9 at 2006-06-23, size: 35M (without X), 75M (with X)
  Kernel 2.6.17 patched, can load the whole CD into RAM, can install to USB key (will erase the whole USB key!)
  To boot system into RAM, only require 96M RAM
  Replace to a newer kernel is easy, just use the website's kernel config and minor adjust with the new kernel (mainly on RAID456 and SATA drivers), and don't patch the kernel with the tmpfs patch, then it will work.
