FW: PCI/ISA riser card

["Taylor, Mike" <mike@buntypost.dundee.ncr.com>]

The LPX riser connector which you describe is something invented by Intel   
and copied (with variations so beware) by other vendors. Try the spec for   
Intel RU430HX Ruby motherboard at   
http://developer.intel.com/design/motherbd/oem/index.htm#RU430HX.

Beware of the 8 pins marked 3.3V, some vendors put special signals on   
these pins, best leave them open circuit.
The INT routing and IDSEL choice is not standard, your BIOS must know how   
the board is tracked. The number and position of the card slots is   
variable.

Has anybody got an opinion on how long LPX will continue or will NLX take   
over?

Regards,
Mike.

Dear PCI experts,
The LPX form factor motherboards have single EISA like connector. A   
  PCI/ISA
riser card can be connected to this EISA connector. Does anybody know   
  where
can I find a spec describing the riser card and LPX EISA connector? A
schematics of this riser card will be very helpful.

Thanks in advance,
