Just to add
The EICAS is the Engine Indicating Crew Alert System.
So, as stated it shows engine indications and....
the crew alert system, which shows:
Warnings
Cautions
Advisory
Memo
+ Status cue.
777 & 747-8 only - MFD(s) show the ECL &/or system pages.
Warnings, Cautions & Advisory messages can generate a ECL on the separate MFD, however not always, as stated some are selected manually or have no checklist and are information only.
Messages with a [] indicate it has a ECL
[] ENG 1 FAIL (press checklist button and away you go)
Earlier Boeing EICAS aircraft require referral to the QRH, but the EICAS messages are slightly different ie no []
ENG 1 FAIL (find it in the QRH)
All require memory items at one time or another.
