Hi,
I have a S1 express and i am trying to use it with a MOTU ultralite firewire sound card. After endless troubleshooting im at a lost of how to fix it. The sound card will flip out every 10mins and send mega static on all the channels, i then have to turn it off and on before it will work again...
I even bought a belkin pcmcia firewire card as it was recommended to fix the problem. Also replaced the winxp sp2 firewire drivers with sp1 drivers.
The only remaining factor which i think could be an issue is my S1 shares the IRQ16 with alot of devices, mainly the ATI X1600;
IRQ16 is used by;
ATI X1600
Firewire Port
LAN Card
PCMCIA chipset
PCI chipset
The only time i can get my sound card to work is if i uninstall the ATI drivers and run in that crappy 640x480 res...
Have tried both omega and ati drivers from lg site.
Ive read that it is not possible to change the IRQ within windows xp in ACPI mode. And the BIOS options on the S1 are extremely limited
Owners of the S1, do you share the same IRQ as I do? Does anyone have any ideas on how to change this without changing my comp to standard pc (and lossing dual core options).
I have tried ot contact LG support, but no reply :|

Looks like no one has the same issue or has tried the S1 with a firewire sound card...?
Can someone with a S1, please just tell me if their firewire port is sharing the same IRQ with anything else?
To do this > Go to control panel > system > Hardware > Device Manager > Then go View > Resource by type > Then Click the Interrupt request (IRQ) plus symbol and see if anything is on the same IRQ as the Texas Instrustments IEEE.
Thanks,

Hi nikkon - nobody is helping, so I might.
I don't have S1, but I know a bit on IRQ issues you described. Yes I guess it is the problem when two or more devices use the same IRQ and is a great problem with video and soundcards (or IEEE controller in your case).
On a desktop you can actually block irq that is shared between many devices in bios in order to make windows ACPI to rearrange devices on a next boot and in most cases it puts the devices on different free IRQs, then you enable it back in BIOS and the problem is solved.
But on a notebook there is no such thing in BIOS, so I reckon the only way of doing that is to either disable firewire in bios if you have that option, install windows and then enable the device. Another trick is that you DISABLE everything you can in Bios (like ports, soundcards, modem or whatever you can) and then install windows, and then turn them on in bios. Hopefully more IRQs will be available and devices will be rearranged in a different manner.
One trick that worked before, but not always is to go to device manager, system devices and delete ACPI controller and ACPI system devices. I'm not sure what else I did (I must have deleted more of those system devices). But once you do it and reboot - it will do the PNP installing of all system devices again, and hopefully will put your IEEE controller to another IRQ.
That is all I can think of for now.
