6.11.7
What is the main advantage of E-IDE over IDE:
(a)
It is compatible with more hard-disk drives
(b)
It allows for larger hard-disk capacities
(c)
It is easier to interface to
(d)
It has a large data bus size
6.11.8
What is the main advantage, apart from increased transfer rate, that IDE has over
older interface standards, such as ST-506 and ESDI?
6.11.9
Explain how IDE differs from E-IDE and how E-IDE supports larger disk capaci-
ties. How does E-IDE use modes to define the maximum transfer rate. Which
mode is the fastest?
6.11.10
Show that the maximum capacity of IDE is 528 MB and that the maximum capac-
ity (per disk) is 8.4 GB for E-IDE.
