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.
