[comp.sys.ibm.pc.hardware] 387SX problems

onyx@loligo.cc.fsu.edu (Jeff Phillips) (03/27/91)

For your 387SX problems, there are a couple things to check:

1) Have your numeric coprocessors removed and reinstalled... 387sx chips are
   VERY easy to install cockeyed or with a bound pin.

2) Check your motherboard switch settings... some manuals on the motherboards
   ERRONEOUSLY indicate that the jumper settings should be a particular way...
   try different settings before you assume the processor is/isn't installed

3) Try to get a hold of CheckIt or QAPlus by diagsoft, or use Norton Utilities
   v5.0 SYSINFO to see if the system recognizes that your NPU is installed.

4) All else fails? Get a new computer (or at least the motherboard) :)

The free utility STATUS.COM from PC Magazine will also show whether the
system finds the NPU.
