Is it a PCI card or ISA card?  If it is ISA then you need to manually
specify the IRQ and Base IO address.  If it is PCI then I don't know
what the problem is.  Maybe it is related to a BIOS setting "PnP OS"
or something like that.

IRQ _could_ be 11, but Linux is free to choose it's own scheme.
'lspci' should give more info.  When in Linux you talk about the "IO"
of the card it is more specifically the "Base IO Address", so that
would be 0xE000.
