Adding missing SATA connectors to motherboard

If you are 86 then your prior threats of violence are funny as hell.

However, we are in a unique situation with modern electronics, you were not working with multilayer surface mount (anything, including SATA ports) for the first half of your life so you might as well cut your age almost in half when trying to claim experience in this topic.

Come to think of it, there was very little that had more than 2 layers before '80, so if that is where your supposed experience comes from, suddenly it all starts to make sense.

Pick up a soldering iron and see what you can do, you are not too old to learn new tricks (if you pull your head out of your ass long enough to actually try). In China people walk in off the streets and do more complex soldering after a few weeks training.

How little you know about modular bios.

Find a different board with the same set of chips and you don't even have to use the same bios! There are also tools to reenable hidden features. They do not write a custom bios for every board that has only minor changes, they just add or subtract modules and hide features.

What you are failing to grasp is why the OP suspected the mod was possible, because he, and I, and others, have already seen and done such things in the past.

DimBulb is certainly AlwaysWrong, but the above is simply bullshit. Perhaps in your little corner of the world you were still using phenolic substrates too but others had moved on long before. We were using upwards of a hundred layers (96, IIRC) on system backplanes and easily eight layers (4P-4S) on plug-in cards well before '80 (the latter were old hat when I started in '74). I haven't done anyting as simple as two layers since college projects, and that was limited by our wierd method (sides were cut individually on a lathe then laminated).

Hundred layers?

We must have a language difference, because that is not even close to true in english.

In fact, I challenge you to find any 100 layer boards, anywhere, ever... within the next 30 years or more.

Just under, yes. Late '70s, yes.

I can't help it if you can't comprehend simple English.

That statement simply shows the world your lack of experience.

Then quit posturing and show us!

Granted, there's not one second I buy this, but let's see what you come up with.

Christ, you can't even do your own math now. YOu really are an idiot.

I am neither.

It is also nothing I ever said. The kony retard that thinks he knows all about PCBs said it.

My first hands-on direct exposure to large multilayer real estate was a 12 layer Control Data Terminal Systems CPU board which held about 400 MSI devices densely packed, made in 1970.

Sorry, I don't have documentation from thirty years ago, nor would I have the hardware to display it.

Of course you don't. You want to live in your little protected world forever. The bigger world is scary, for those with such a limited mind.

You are, in fact, both.

You're also CantRead.

IBM mainframes. Our standard boards were 10 layer PWB + wirewrap overflow and customization in the '60s. The plug-in cards (nominally 18 per board) were usually 8 layer. Four were needed to power the ECL. In the late '70s things shifted to 100 (then 121) chip MCMs on huge boards (~3'x3', IIRC). These pretty much went away with the ECL processors. CMOS packed more into the chips without increasing the board wiring density much. The number of layers on the MCM boards was dictated by timing and impedance control required as much as density.

At the risk of damping down this lovely flame war, here's a 2004 article on the IBM z990 series machines that discusses the module and board layer buildups in detail:

The net: 110 layers in the modules and 30 in the cards.

We know...

I didn't work on the 'z' series (left for BTV during the ES9000 to 'z' changeover).

Thanks Phil. The 3081-ES9000 boards were much larger and had more layers (lower integration by several orders of magnitude). I did a search on the ibm.com site and didn't turn anything up on the older stuff ("Clark Board" was some sort of philanthropic organization, or something).

Go back to the kook group, ditz.

Yes... you know... NOTHING.

Talking to and about yourself again.

While that is interesting, it isn't a 100 layer mainboard PCB? It seems we are not talking about the same thing, although a search of the document did not find "110" anywhere, what page is that on?
