I have two QD21's - one says rev F and the other says rev G, but both have E65G markings on the eeprom. I will plug them both in and verify shortly, but I would guess that means they are both G. Can I just use the rev J firmware instead? I assume J is 'better' than G... -brad -------- Original Message -------- Subject: Re: Emulex QD21 firmware From: Glen Slick <glen.slick at gmail.com> Date: Mon, June 25, 2012 9:25 pm To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> I have the following versions of firmware EPROMs for the Emulex QD21: E65C - 16KB E65G - 32KB E65J - 32KB There no text strings in the Rev C firmware and no on board Firmware-Resident Diagnostic.
