So what is the deal with the write-back and busmaster controllers?
Could that have been why our intel DX4 100 was dumping core and panicin'
(Adaptec 1742 EISA), what would have worked, write-through? 
At least when it panicked it would write out the memory image and .core
file @48 megs (ouch).

We put the intel DX2 66 back in and problem went away. Sure miss the 
speed the DX4 100 had.
