[vortex] IRQ problem

I have just installed a 3C900 Combo card and have great
troubles of getting the system to work with the card.
The card was used in another machine before, however 
another 3C595 behaved similar.

Kernel 2.0.38 with the driver fram 3Com (same result with
the one found in the kernel release). 

When I try to access the card a message like this comes up:

Sep  2 01:11:57 gina kernel: 3c59x.c:v0.99H 11/17/98 Donald Becker
http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html
Sep  2 01:11:57 gina kernel: eth0: 3Com 3c900 Boomerang 10Mbps Combo at
0x6000,  00:60:08:57:d6:06, IRQ 255
Sep  2 01:11:57 gina kernel:  *** Warning: IRQ 255 is unlikely to work!
***
Sep  2 01:11:57 gina kernel:   8K word-wide RAM 3:5 Rx:Tx split,
autoselect/10baseT interface.
Sep  2 01:11:57 gina kernel:   Enabling bus-master transmits and
whole-frame receives.

IRQ of 255 seems strange. 

I do not know any way of setting the IRQ for PCI cards.

The other interrupt lines are as follows:

gina.uio.no 52>cat /proc/interrupts 
 0:     178646   timer
 1:       3735   keyboard
 2:          0   cascade
 3:          7 + serial
 9:       4525 + aha152x
11:       2011   HiSax
12:      71858   PS/2 Mouse
13:          1   math error
14:      83610 + ide0
15:          7 + ide1
gina.uio.no 53>

Number 4, 8 and 10 are free to use.

Any suggestions of what might be the cause of this trouble ?

Please answer to me directly, since I do not read this mailing
list.

Thanks in advance!
