Good day all!

I have been thoroughly impressed with what Linux and especially Knoppix has to offer. I have been a Windows user for 7 years (grew up with it without exposure to other OS'es).

I have been trying to get Knoppix 3.3 installed on to an older system. Its specifications are as follows:

Intel PR440FX Dual Socket 8 (Dual Pentium Pro)
2X Pentium Pro Overdrive processors (PII 333MHz Klamath core, 512KB full speed L2)
4X 256MB EDO ECC Buffered DIMMs
Adaptec ANA-6944A/TX 4 Port PCI NIC
160GB Maxtor D540X hard drive

During the file copying process, the system halts and this message appears:

unable to handle kernel paging request at virtual address 02000000 printing eip: c013dc28
Oops: 0002
autofs4 af_packet efs hsf minix nls_iso8859-1 ntfs xfs reiserfs ext3 jbd cs4232 ad1848 uart401 sound

Though I am not sure, it seems that I have a hardware problem. The first line mentions a problem with virtual memory. Is that in reference to the swap partition? I find it difficult to believe that my hard drive is faulty because I have tried to install on more than one hard drive with this system, but the same problem keeps reappearing. Also, I have tried a hard drive from a failed install on this setup and successfully installed Knoppix on the hard drive with a different computer.

My next guess would be that I have a faulty DIMM somewhere. I sincerely hope that this isn't the case, but I will try to factor out the variables. I have run multiple loops of Memtest86 on the DIMMs and all have passed without a problem.

I just want to see if you guys have any ideas as I have limited experience with Linux. In the meantime, I'll try to factor out the DIMMs by trying to install with only one DIMM at a time.

Thanks for any help!

EDIT: I forgot to mention that Knoppix boots successfully as a Live CD, (even detects and properly configures the ancient 4 port NIC - Awesome!). I have played around a little in that mode, but prefer to have it on a hard drive now, which brings me to this situation.

EDIT 2: I was able to successfully install Knoppix. All I did was take out all but one DIMM and everything proceeded normally. I will test the other DIMMs as I go along later. This edit was made off my new Knoppix box!

Get on the internet and do a search for memtest86, and make a memtest floppy.

Untar the memtest86-3.0.tar.gz file by using (assuming you also get version 3.0 if you get a newer version use that version number:

tar -zxvf memtest86-3.0.tar.gz

cd memtest86-3.0
and (as root) place a floppy disk into your floppy drive and issue the following command:
dd if=precomp.bin of=/dev/fd0
which will write the precompiled binary to a floppy (Note: /dev/fd0 is f d zero)

then put your second stick of ram into your box and boot to the memtest floppy, so it can test your ram.
