A: The Serial Number is the long bar code sticker and the PWA Number is the short bar code sticker. They are located on the back edge of the board next to the BIOS chip.

Q: My motherboard manual says "Diamond Multimedia", but the BIOS reports the manufacturer's code to be BCM. The Diamond website doesn't have any information on this board. Can I use this KR632 website to support it?


A: Yes. You are welcome to use our FAQ, drivers, and BIOS updates to support your board. However, you can not use our RMA service as Diamond Multimedia must support you for repair, replacement, or technical support.

I/O Port

A: No. We are a board manufacturer, not a distributor. We do not manufacture or recommend any IR ports, but we provide the IR pin out information in this FAQ.

Q: I am trying to add an IrDA. What is the pin out for the IrDA connector?

I/O Port

A: IrDA Connector pin out is as follows:

1) VCC

3) IRIA (IR receive)
4) GND
5) IROA (IR transmit)

A: No. Celeron FCPGA 533MHz is also not supported.

Q: Can I use a Celeron 533MHz PPGA by using 370 to 1 converter card?


A: Yes. You can, but be sure to update your system BIOS to the latest which is A10 first before proceeding to do so.
