Dell Dimension L800cx    with 4 PCI slots (but no AGP slot)
- I upgraded memory to max (=512MB)
- I fitted PCI cards for: sound, USB2.0, ethernet, and SATA
- On board graphics sadly uses only 4MB shared memory
- Tried PCI graphics card years ago and altered BIOS accordingly but BIOS wouldn't use it - totally blank screen!

Your report shows 2 "rng" items work but dmesg indicates not working:-
# dmesg | grep rng
intel_rng: Firmware space is locked read-only. If you can't or
intel_rng: don't want to disable this in firmware setup, and if
intel_rng: you are certain that your system has a functional
intel_rng: RNG, try using the 'no_fwh_detect' option.

Your report shows kernel=v2.6.25 but uname -a shows kernel=Linux puppypc

Thanks for your excellent service.  - Bob Brown in UK
