- Hello. I am in the market for a 486 33DX and upon reading
- several ads I became most confused.
-
- Which bus is better for Video I/O ?
- Which bus is better for IDE disk I/O?
-
- I have allways though that local bus was better than EISA,
- but I saw an ad claiming various performance boosts for
- IDE controllers.
- Basically, this is what it said:
-
- ISA IDE = 1
- VESA LB IDE = 2x
- EISA IDE (32bit) = 4x
-
- Saying, a local bus IDE is twice as fast as a ISA IDE, and
- a 32bit EISA IDE is twice as fast as a VESA LB IDE.
-
- Can this be right, or are they trumping their more expensive
- EISA busses?
-
- If in the future I wish to ad a CD-ROM and a sound card,
- is EISA important if the machine has a local bus slot?
- (Most machines seem to have 2 local bus slots, and I assume
- that a local bus video controller and a local bus IDE controller
- both occupy the slots, leaving no room for CD-ROM, unless
- maybe we get IDE CD-ROM controllers.)
-
- Please e-mail responses to CBALLEN@HUBCAP.CLEMSON.EDU
- Thanks.
