Use apt-get install to install the lshw package on Knoppix. It has a small |

footprint and it should hopefully not exhaust your RAM. |

Hmm, is there a BIOS firmware upgrade you could perhaps flash it with? |

Can you swap around the RAM modules or remove them one at a time until you |
| 30 |
find the culprit? (not sure if you tried that already). |

POST error. Could be due to dodgy memory. Have you tried removing the CMOS |
| 49 |
battery and then reflashing the BIOS with the latest firmware? |
