As CaptainSandL pointed out, the bleed air reset with EAI On proc detailed in a Boeing issued FCOM bulletin to rectify a Bleed trip during a No-Bleeds T/O caused by the incapacity of the High pressure relief valve to vent sufficient pressure at t/o with bleeds off. Noteworthy is that Boeing only issued it for the Classic as the NG has a redesigned high stage relief valve.

An interesting read on this topic is the recent depressurisation of VH-VBC, a
Boeing 738 at Coolangata Australia. The report is available at the ATSB website.

Cheers,
MHA
