Description of problem:
I have a Toshiba 480 CDT laptop.
I've installed Red Hat 7.1 and when i boot the i have this message :
Starting PCMCIA : PCI: no IRQ known for interrupt pin A of device 00:02.0 Please try using pci=biosirq
PCI: no IRQ known for interrupt pin B of device 00:02.1 Please try using pci=biosirq.
It's impossible to do anithing after that : The PC is crashed.
Steps to Reproduce:
1.Start the PC
Actual Results: Crash
Assigning to kernel.
Did you try adding "bios=biosirq" at the lilo prompt ?
I've resovlded the problem by changing bios (6.90 version) values :
I changed PC card controller mode : I turned it to PCIC Compatible instead of auto selected and now it works fine.
It's strange, i did not have this problem with the suse 6.2 ...
Suse 6.2 (and older Red Hat versions) used the cardbus controller in a different
way. The "new" way makes it, in general :), much more reliable and faster for
things like networkcards. However it seems that your laptop didn't like that in
