 Hello, thank you,

 The Jensen has got exactly 6 EISA slots and the system board, so 
 there should only the slots 0, 1, 2, 3, 4, 5, 6 being found.
 
 I have installed and configured 3 EISA cards in the first three 
 slots, number 4 and 5 are empty and number 6 contains an ISA network 
 card which I left unconfigured in the ECU.
 
 The card in slot 1, however, is found as ISA, not EISA by the SRM 
 while the real ISA card is not seen by the SRM console at all.

 I don't know much about this stuff, but I wonder if the problem is 
 really here where it "sees" the slots 8 to 15.
