Fw: installing a pci-x serial card in a 2850

[Brandon Coale]

FYI, if anyone else is in a situation where they need to add a pci-x serial
card under RHEL.

I ended up scrapping the SIIG card and purchased a pci-x card from vendor
StarTech, part number PCI2S5503V, website:

http://www.startech.com/Product/ItemDetail.aspx?productid=PCI2S5503V&c=US

This card was automatically detected by RHEL4, and it has two serial ports:

[root at localhost ~]# dmesg |grep -i 16550
Serial: 8250/16550 driver $Revision: 1.90 $ 8 ports, IRQ sharing enabled
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS4 at I/O 0xbce0 (irq = 50) is a 16550A
ttyS5 at I/O 0xbce8 (irq = 50) is a 16550A
[root at localhost ~]# setserial -g /dev/ttyS*
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
/dev/ttyS4, UART: 16550A, Port: 0xbce0, IRQ: 50
/dev/ttyS5, UART: 16550A, Port: 0xbce8, IRQ: 50
/dev/ttyS6, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS7, UART: unknown, Port: 0x0000, IRQ: 0

I let my Dell S&P rep know about this StarTech card as well.

Thanks,
Brandon

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
