Updating seagate firmware on a mac
The firmware is a built-in chip on the device that contains programming code.
You can change the firmware on a Seagate HDD as a troubleshooting method.
If there's an easier way (installer check edit, etc) send a note. (Several reports below have notes on OS X Lion with C2D updated 2006-08 Minis.
While I can’t condone this activity I must say as a curious and tech savvy student I would have done the exact same thing…
with that in mind I have reproduced instructions as they were provided to us below: This should work on both EFI (Intel) and OFI (PPC) based Macs.
The early Intel-based i Macs also had a socketed CPU and there are a couple C2D CPU upgrade reports here on those.) This page has pre-2009 model Mac Mini owner comments on Core 2 Duo (and some Core Duo) CPU upgrades as the (2006-2008 mfg) Intel-CPU Mac Mini has a CPU socket on the logic board (as did early Intel-based i Macs).
Some reports include notes on updating mac mini 1,1 efi firmware/bootrom to mini 2,1 version for 3GB RAM support vs 2GB w/mini 1,1 - Guide to Flashing Mini 1,1 to 2,1 at [ If anyone knows of another mirror of the Firmware DL, let me know.] There were several news page posts earlier in 2006 on Core Duo CPU swaps (before the Core 2 Duo), although they are not listed here, except for the one that included a step-by-step guide on Mini CPU swaps from early May 2006 (see (2006) Mac Mini Intel CPU Upgrade Guide) and later posted ifixit guide).
