installing a pci-x serial card in a 2850

[Brandon Coale]

Hi,

I bought a PowerEdge 2850 preinstalled with RHEL4 two months ago, and would like to add a second serial port.  My Dell Software&Peripheral rep sold me a SIIG PCI-X card.  

The vendor SIIG doesn't officially support this card in Linux, but I installed it anyway to see if it would be autodetected.  It did not get autodetected by the serial driver.  One thing that is interesting is the vendor's specs for this card says it has a 16550 UART, but the lspci output shows it as 16950.

Does anyone know if there is a simple way to get this card working, or would I be better off buying a card that supports Linux?

Below shows my lspci output, dmesg output, setserial display, and the link to the vendor's card.  The built-in serial port is enabled as COM1 in the bios, and shows up in the output.

Thanks,
Brandon Coale
