Hi All,

I did think of trying to dig up a EISA configuration utility to see if that 
may be the problem. It did however boot and run quite well under 4.xx on a 
uniprocessor kernel, without any reconfiguration of the EISA bus. Under 4.xx 
it also did a machine check under a SMP kernel. Apparently, the 2100A is quite 
an evil machine with it's split PCI bus, I did remove all PCI cards from the 
machine, as there were reports a machine checks with certain cards. Removing 
the all the cards had no effect, however.
