Official information is not available. You only know what you can find out by reverse engineering.

Hi Rahmon,

Don't believe everything you read on the internet. In my experience I've found that these kind of displays don't bother to implement the commands that the phone will never use. Perhaps this is to save money. You may have found one of the commands that simply doesn't work on that display.

I have a display of Nokia 6280.
On the Internet write that it is compatible with MC2PA8201
Hardware scrolling does not work
Void MC2PA8201_ScrollArea (uint16_t y, uint16_t pos) {
  Uint16_t bfa = 320-pos-y;
  Wr_cmd (VERTICAL_SCROLLING_DEFINITION); // 0x33
  Wr_dat (y >> 8);
  Wr_dat (y);
  Wr_dat (pos >> 8);
  Wr_dat (pos);
  Wr_dat (bfa >> 8);
  Wr_dat (bfa);
}

Void MC2PA8201_SetScrollPosition (uint16_t pos) {
  Wr_cmd (VERTICAL_SCROLLING_START_ADDRESS); // 0x37
  Wr_dat (pos >> 8);
  Wr_dat (pos);
}

When you call MC2PA8201_ScrollArea (0.320);
The screen switches to portrait mode
When you call MC2PA8201_SetScrollPosition (uint16_t pos) in the loop, nothing
Occurs
How to solve this problem?
On the Internet write that this display stands in Nokia 6270/6288/6265/6275/6282
Where can I find the description of the commands for this lcd?

Here's the final WIP, awaiting for review/P91 pinout confirmation.

Hi all, I'm working on an "not-so-official" pinouts guide for the Z800 mb and I'd like you attention to P91: MEMORY FANs: fisrt attachment

Please help me fulfill the "P91 MEM FANS" pinout and I'll post the complete pinout guide WIP for review.

Hi msilveira,
LOL
Booted 1st time after pulling a CPU.....
in retrospect I guess low voltage means higher current ??
maybe trying to step from 12gb to 96gb is too much power drain ?

Thanks again
to all who have posted
Paul

You may try another low power GPU, and try adding one pair of memory stick ( 1 per cpu )  a time ...

Thanks for your response Andy. I'm currently booting off of dual 56xx quad core CPUs, so I was wondering if anyone else has seen a board like mine in the wild that works with them.

It might be worth mentioning it has a sticker on it that says 'Property of Hewlett-Packard Company' 'Not For Sale' etc. (attached) and it originally had a Intel Confidential Nehalem-EP 130W w5580 in it.

I want to upgrade it as high as I think it can go, ideally a X5678 (Quad) or X5690. At the low end of my expectations, it might just make sense to get a second W5580. or a X5650.

Let me know if you have any thoughts. I upgraded the BIOS a while back to revision 3.57 I believe.

Hi all.
I'll soon post my build, in a week or two.

But now, I REALLY NEED an information about the DPS-1050CB PSU.
I just got one, used, and I need to know a simple thing: Is it normal for this PSU ( or DELTA/HP's PSUs  ) to turn on when powered without the 24pin ATX connected to a Mb?
If I plug mains without a mb connected, it turns on, as if shorted GND + PSU_ON pins.
If I plug mains, with the 24pin ATX connected to the mb, it works as expected.

Is this behavior correct? I need to know before I pay the dealer.

You should be fine with all 55xx quad-core CPUs. You will run into problems if you try the hex-core 56xx CPUs. People are reporting that most problems are with dual-CPU combinations and you can probably use a single hex-core CPU without any problems.

Do you have a particular upgrade in mind?
