Adam,
My understanding is that the Micro-2000 POST-Probe [5] is the only one that can be powered from 3v3.

call me stupid, but where does it say it is an 3.3V?
It doesn't, and this is an important point that I am trying to clarify with their engineers who claim that it will work from 3v3. As I said, if anyone can recommend something better I would love to hear about it.

Allright. As far as I can tell it is 5V card. The red PCI book Chapter 15 : MECHANICAL SPECIFICATION CONNECTOR PHYSICAL DESCRIPTION PG 471 [..] The same physical connector is used for the 32-bit signaling environment voltages. In one orientation the keys accept 5 volt boards. Rotated 180 degress, the connector accepts 3.3 volt signaling boards. The pin numbering of the connector changes (!) for the different signaling environemtns to maintain the same relative position of signals on the connector.

and there are now motherboards that won't power on with a 5V post card in ANY PCI slot. ron

Another option is to use a miniPCI to PCI adapter which you can plug your regular 3.3V PCI POST card into. http://www.interfacemasters.com/products/pci_tools/mini_pci_to_pci/index.htm... --Bari

yeah, with the $65'000 question being where do I find such 3.3V POST card. -- Adam Sulmicki http://www.eax.com The Supreme Headquarters of the 32 bit registers

We build lots of our tools. Check with NSC. They have a PCIWatcher Debug Card that has a LCD display and has buffers to pass the data to a RS-232 serial port. It captures not only port 80/84 but all PCI I/O, memory, cinfig, INTacks, etc. --Bari

Yeah, but the trick is to find an 3.3V PCI POST card. I finally got it from http://www.postcodemaster.com/products2.htm It is PCI Version Part #PCIPCM-11 The one listed on their web page is an 5V, but if you ask they can modify it for you so that it works with 3.3V PCI. In fact I just got it today and I was able to use it to get POST codes from IBM ThinkPad T23 which has 3.3V MiniPCI slot (I would use here IM300 MiniPCI->PCI adapter), and which would not work with my old 5V post card. Also they have an MiniPCI POST card (#MINIPCM-10) which could be used directly without adapter, but I have not tested this one. -- Adam Sulmicki http://www.eax.com The Supreme Headquarters of the 32 bit registers
