Modem hell, ..
 

I'm currently trying to get online with my Mandrake 9. but running into all kinds of dismay.

Internal Winmodem is the Conexant modem .8086 2046, . and when I installed the hsfmodem it gave me all kinds of problems, and now I'm trying out a basic serial modem ( Netcomm brand)

This is what I have done so far.

There is only one serial port on the laptop, . and a reference through Windows shows the same, . Just COM1,. (ttyS0).
After installing the external serial modem, I tried echoing the device by using echo ATZ > /dev/ttyS0 and no response from the modem. So I ran dmesg | grep ttyS and it came back with ttyS0 at 0x03F8 (irq = 4) is a 16550A. Fair enough, it's showing that it's there. But for some reason it's not seeing the modem on the other end.

So I did just a dmesg and looked through the return.

ttyS0 at 0x03F8 (irq = 4) is a 16550A
pci enabling device 00:1f:6 (0000->0001)
No IRQ known for interupt pen B of devce please try using pci=biosirq.

Now I'm aware that this needs to be done in the lilo.conf but what is it's format s'posed to be?.

I still can't get a response from the modem, is there anything else I can try, . after fighting the winmodem for several weeks, i just wanna connection, . yanno?

ANy advice out there I would be more than happy to try, if you eed any more info I'll give that a go as well.

Robby.

Re: Modem hell, ..
 

insert the line:

append="pci=biosirq"

near the top in your lilo.conf file. Rerun /sbin/lilo as root.


Do the lilo thing and then see if you can get it to dial out using minicom.

Modem problems
 

I have been reading the threads here, and noticed that I was getting the message "Please try using pci=biosirq" as described by others here. I have added the append="pci=biosirq" in the lilo.conf file, refreshed lilo as root, and even re-bootred the machine, but I still get errors on trying to load the modem driver, and still get the 'Please try using pci=biosirq" message in the dmesg output.

Can anybody suggest why I still get this message when I have added the line
append="pci=biosirq" immediately after the line default="linux" in the lilo.conf file ?

Many Thanks,

Mick

Re: Modem problems
 

No idea as to why it keeps coming up, but here is what kernel-parameters.txt has to say about why you would need it:

"Use PCI BIOS calls to get the interrupt routing table. These calls are known to be buggy on several machines and they hang the machine when used, but on other computers it's the only way to get the interrupt routing table. Try this option if the kernel is unable to allocate IRQs or discover secondary PCI buses on your motherboard."

So if you are not having problems with your IRQ's then there is no need to add this to your lilo.conf file.


What modem are you trying to get going?
