Kernel for Pentium 4 686


I tried installing Ubuntu 12 Net install on friend's computer but got an error message that the kernel is incompatible with the architecture. He has an old Dell Dimension 3000 desktop that runs Pentium 4 CPU.
I also tried installing 64 bit Mint 17 but that failed as well.
I thought the Ubuntu was 32 bits for some reason, but I'm not thinking that it might have been the reverse.

Is there a special kernel I need to use for Pentium 4 CPUs?

It is a 32 bit. What it isn't is PAE, and likely the kernel you installed was a PAE kernel.

You might check to see if a non-PAE 32 bit kernel is available.

You do need to only use 32 bit to start. It may be that you just don't have enough ram. As noted above a non-pae would be needed.

See if a knoppix 3.4 cd will boot.

Hi,

Ubuntu has both 32 and 64 bit installers. If the machine is 32 bit you should be using the 32 bit installer. Eg the second option in the "Choose your flavour" menu at http://www.ubuntu.com/download/desktop

HTH,

Evo2.

In case it helps, on Slackware --Current,

Code:
$ uname -a
Linux tuna 3.14.17-smp #2 SMP Mon Aug 25 15:18:59 CDT 2014 i686 Intel(R) Pentium(R) 4 CPU 3.40GHz GenuineIntel GNU/Linux
I do have 4GB RAM.

Since you are using Ubuntu it is almost certainly a PAE problem.

There are three workarounds provided at:

A Pentium 4 has pae. For the record, the only Pentiums that lack it are the Pentium I and those Pentium Ms with 400MHz FSB. Actually, what you have is a Celeron D, but that's just a cheaper, lower-performance Pentium 4.

I suspect you've downloaded the 64-bit version by accident.

It is still possible for PAE to not work:

http://askubuntu.com/questions/11774...es-not-present

which states "...old systems which have the memory controller on the motherboard may not "expose" the CPU's PAE support, effectively making them non-PAE".

Hi ventsyv,

There were Pentium 4 Extreme Edition (EE) CPUs that were at least for the most part 64 bit.
However, The Non-EE version P4's that I can find data on were all 32 bit.

Your friends dell 3000, if it is a dimension with a non EE version Pentium 4 is most definitely a 32 bit system. To check, boot the Ubuntu install disk and run the memory test from the main menu. If the mobo/BIOS cooperates (as it hopefully should), it will indicate the chip-set and CPU version and may mention if it has PAE support.

You can let it run a pass or two and post what the static data on the upper part of the screen says. That could/should help us determine the CPU Type and bit width and also the chip-set which can help us give you a more conclusive answer.

However, If it is a non-Extreme Edition Pentium 4, it is most likely a 32 bit machine. Insure the OS you are installing is also 32 bit.

P.S. I Have a Dell Dimension 3000 2.8 Ghz w/2GB RAM (400Mhz) dual channel running Debian Wheezy 7.6 here and it is 32 bit and has PAE support and runs well.

Hope that helps,
Tim

Regardless of PAE or not a 686PAE will work on a Pentium 4. P4 is probably the only old Pentium I would bother with PAE on all the earlier ones I would just use a 486 kernel with. I agree with DavidMcCann the OP has probably downloaded the amd64 iso.
