| Can any one tell me the important differences between EISA and ISA busses.

  EISA costs more. With correct cards *and* software capable of using
the extra bandwidth you can get better performance.

| why not get a EISA bus?

  In addition to cost some ISA boards don't work in some vendor's EISA
busses. I would be sure there was a need for it before going EISA at
this point. I don't believe everyone who sells one has their act totally
together. Configuration of ISA boards in an EISA system is a royal pain!

  Don't know if that helps or not. We've had enough funniness with EISA
timing to avoid it when not needed. When the boards come down in price
or for top end applications it will be a better buy. In particular
multiple disk controllers or a multithreaded controller would benefit
from the bandwidth, assuming a multitasking o/s was being run to take
advantage of it.
