- Are any of the advantages of the EISA bus lost if ISA cards are used in
- an EISA system? I've heard that if any ISA cards are present then the
- EISA cards may not perform and/or function properly. Is this true?
-
- Here are some of the things that I've heard:
-
- - that the presence of an ISA card prevents EISA cards from doing
- DMA to/from memory above the 16meg line.
- - that the presence of an ISA card reduces the performance of EISA
- cards.
- - that some unspecified problems or limitations are encountered.
-
- If anyone could confirm or counter any of these statements, it would be
- really useful to me.
-
- P.S. You're right! This is a resubmission of an article that I posted a
- few days ago. My first article was too vague.
