Very Computer

Hi there,
        has anybody had a problem running linux on an Intel DX4 100 OD?
I have both Win 95 and one of the lastest slakware versions of linux and the
Win 95 works fine but linux soon hangs. If I put the previously installed DX33
back in every thing seems to be fine. I was wondering if it might have some thing
to do with the fact that the on baord voltage regulator interfers with the signal
generation for other devices such as the VLB graphics card since it does not
immediately respond when the machine is started from cold - but does come to life
after several presses of the reset button. Again the graphics card is fine with
the DX33. the trouble is I can't decide if it is a hardware fault with the chip,
or, ignoring the boot problem, if it is a problem with linux.

Any ideas? Should I just trade the DX 4 100 for something else or is it fixable?

many thanks

Roger

I run an AMD 486DX4-100MHz.  Never had any problems with it.  Perhaps your
MB settings aren't correct?  I don't know much about processors, but I know
that processors do come in different voltages; perhaps you're running a new
5V processor in a 3.3V socket, or something similar?

Dunno for certain, just a guess ...

        I'm using a 486/100 intel and it runs fine. I have
        a vlb graphics card, vlb disk controller, and an
        ethernet card in it and I use to have a modem in
        addition, so it's not the type of problem you
        describe. The voltage regulators should only drop
        the voltage to the chip, I can't see how it would
        couple to anything else. You might want to take
        everything out and clean it up and reseat the boards.
        Make sure you are seating the cpu well and that the
        lever on the ziff socket is secure. look at the pins
        on both the 33 and 100 and see if you see any anomaly.
        good luck, the 100 works really well.
