Oh no, EISA cranks out speed, if you have the right boards.
EISA bus mastering boards can blast 32 bit data directly into RAM
using a seperate data path in the chipset.

There's EISA. I thought it was an okay bus

cheaper. As for other non-jumpered busses, Sun's Sbus is nice.
Didn't EISA also suffer from still being slow? I seem to remember that
it didn't gain much/any speed over ISA, just that the data path went from 16
to 32bits, allowing it to move more data at the same bus speed? To remain
compatible with ISA, it would seem they'd have to retain the original bus
speed as well.
I've always thought it was too bad that things like VLB didn't appear
with the 80386 when it was really needed.
