The problem appears to be caused by the fact that your Dell CD and the recovery console CD that I sent the link for will not allow you access.
The reference to the PCI is probably a reference to your grpahics card or some other hardware you have inserted in a PCI slot.
If it is the graphics card it is unlikely that it has failed, as Puppy allowed you access.
If you have any cards except the graphics card in a PCI slot, for instance a sound card, rather than the onboard sound or a wireless adaptor card then take them out.
It may also be that the recovery console link I sent you may be better with a try on this one, download this please on another computer.
Please download ARCDC fromArtellos.com
- Double click ARCDC.exe
- Follow the dialog until you see 6 options. Please pick: Windows Professional SP2 & SP3
- You will see a few dos screens flash by, this is normal.
- Next you will be able to choose to add extra files. Select the Default Files.
- The last window will allow you to burn the disk using BurnCDCC
Your ISO is located on your desktop.
It appears the memory is OK, if it is not Puppy will not usually run, as it does so in ram.
WHAT exactly please is the LABELLING on the CD`s you have from Dell.
Do you have one titled reinstallation CD.
