So I now have my EEPROM BIOS USB Programmer CH341A + SOIC8 Clip + 1.8V Adapter + SOIC8 Adapter at hand.
I also have my bios update folder with ImUpdate, SFlash16, and 128MBDOS IMG File. I am trying to the best of my current still very limited understanding to figure out the next step without...
Ok, I downloaded the firmware and the Intel easy Clean ME, but forgive my current lack of knowledge: How to deploy these windows programs on a Mac computer which does not boot is an enigma to me? I have been searching here and googled there, but any clues and /or discussion assume that the...
I managed to get the ASD3S150 installed on USB,and am currently running the EFI test. Took a bit of doing, such as SMC reset,as well as 1)disconnect existing on-board screen, 2) HDD and 3) battery, to convince the machine to display on an external monitor. So I selected "All Tests" and to...
Thanks for getting me up to speed on proper board etiquette. Point taken.
Wow, reading up still on Mini Pro TL866 and this whole aspect of Bio chip reprogramming. CH341 as well. Cant hurt to buy one of those units and give them a whirl. Could not get much of a handle on the 'Medusa 2' reference...
Hmmm interesting. Thank you for the pointers, and I definitely follow them up.
I am going with a focus largely on Macs right now, and shall read up on Medusa 2 then. I am not concerned with staying in business, but I just like to be able to maintain machinery of all sorts. I like up-cycling...
Roger that Houston, I will be onto it later today, and post results.
Regarding your earlier pointer "If you don't have Medusa 2, then need to pull out SPI chip and reprogram it with external programmer; like CH341, TL866, nano BIOS programmer, many out there," that sounds way over my head ...for...
Yay, I think I have found the ASD 3S150 , it is currently downloading from "Vinafix" : https://vinafix.com/resources/apple-...ics-3s150.1255. So once this is in my twitching fingers, I shall proceed and diagnose the unit. Man, that was a bit of a walk on the wild side...
It is a 2012, that much is confirmed. Looks like I need to learn more about torrents and join the 'advanced reworks' forum to lay hands on ASD 3S150 for this rig...Tenacity its where its at, to get a problem solved, as usual. However in the meantime I scored the ASD disc images for my favorite...
It would appear that the 820-3115-B is a 2012 model, but of course I cannot be sure. I found some ASD links and instructions for the older models up to 2010, and I am downloading as I write. The ASD 3S150 is still elusive, but I will hunt it down, maybe with some help?
OK 2informaticos, thank you for the pointers again: I have been trying to inform myself on these processes you suggested, but I am running into walls.
As for the clean ME , I looked, amongst others, at this link: https://www.laboneinside.com/how-to-...egion-problem/
At the end of the article it...
Thanks , JohnB. I thought that I covered that possibility by disconnecting the internal Sata cable and booted off an external drive...with the same result of only partial boot up.
Newbie, my first post, please cut me some slack, do not have all the lingo down yet:
This machine has green light on mag and will boot with chime as soon as I plug in mag charger. The screen stays black, but when I put in external monitor it will show logo and load about 1/3 and hang. So far I...
