<DIV dir=ltr><FONT size=2>The mainboard is K7SEM and irq_tables.c is already in
the source tree.</FONT></DIV>
<DIV dir=ltr><FONT size=2>I run the program getpir and get an irq_tables.c file
which is the same</FONT></DIV>
<DIV dir=ltr><FONT size=2>as the one in the source tree. The program util/getpir
reports 6 slot found,</FONT></DIV>
<DIV dir=ltr><FONT size=2>whether I plug in the multimedia card or not, and
produce exact the same irq_tables.c.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>And the option HAVE_PIRQ_TABLE=1 is set in the config file of
the source tree.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I traced into the kernel source and found that the original
BIOS set IRQ when POST,</FONT></DIV>
<DIV><FONT size=2>but linuxbios does not do so. The IRQ is 0 when start up with
linuxbios. </FONT></DIV>
<DIV><FONT size=2>When the driver of the multimedia card comes up, it find the
card has not an IRQ.</FONT></DIV>
<DIV><FONT size=2>Then the driver try to get one from the irq_table, but the PCI
device is not in</FONT></DIV>
<DIV><FONT size=2>the irq_table, so it can not find one or assign one to the
device. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>What else can I do? Can I hard code one irq to the
card? </FONT></DIV>
