After  many  weeks  of configuring a  small  network,  everything 
seemed to be in place until Friday. ** DMA TEST FAIL !! ***

System 486DX-100
       heatsink+Fan

Motherboard PCI Bus Mainboard (48 and a BIG 6 on the manual)

The IDE is disabled and I'm running two SCSI hard disks of a  BUS 
LOGIC  BT545S. All was working fine until we tried a new  network 
adapter  and  at  one stage of configuring  Windows,  the  SYSTEM 
directory was scrambled and we got gobbledegook on the screen.

Next, when the system. just before the drives are identified,  we 
got the message  ** DMA TEST FAIL !! ***

Pulling  the network card and trying again, the system seemed  to 
work fine till now. Now I can;t get rid of the message at all.

I have tried swapping the SCSI card for another, a Future  Domain 
16 bit card and with that card the system just stops at the  SCSI 
ROM signature. The BUS LOGIC card works fine on another system.

Question 1 - where is this message coming from?

             a) CPU
             b) Motherboard

What can I do about it?
