Re: [newbie] IRQ conflict help

CM18738-MC6 is the onboard sound and I'm using the onboard LAN as well. There is a conflict between the SCSI card and the Nvidia stuff. I can put the SCSI card in any of the slots - still conflicts. If I add the WinTV tuner card back in, I usually get 3 things using one IRQ. This can't be good. :-) PNP is turned off in BIOS and the PCI stuff is set to AUTO. I can set it to manual but all that does is let you pick PCI DEVICE or LEGACY for each IRQ. Any ideas on how to use more than 2 cards with 6 slots and 16 IRQs without something conflicting. Software with the cards suggests using Device manager to switch IRQs (heh)...as ifNo Windows here :-) Thanks all. PS I did search Google for help but I found nothing immediately useful. PSS I've got my HD on as master, IDE1 and my Zip as master, IDE2. If I put the Zip as a slave on IDE1, can I turn IDE2 off and gain an IRQ back? Want to buy your Pack or Services from MandrakeSoft?

[newbie] IRQ
I suspect the freeze problem I mentioned earlier is to do with IRQ conflicts, but how do I change IRQs? I've looked up every configuration tool I can find (Control Centre, linuxconf, webmin) and couldn't find anything that allows me to assign IRQs, or indeed do much at all to my hardware profile.

When using Linux IRQ assigning is handled by the BIOS, so your only chance would be to try and reserve IRQs there (e.g. for Legacy ISA devices) which then frees up and the IRQs rearrange. Another option might be to physically reseat the cards in the slots, however I am not sure if it has any effect when BIOS is handling the IRQs.

Re: [newbie] IRQ`s
FS Hello i have a little problem with my irq`s . FS Since i have quite a lot of hardware in my box there is some sharing. Now the FS problem is that my wintv card shares an irq with my GeForce and since it FS crashes my complete system after running xawtv or zapping as well as any FS other tv prog its obviously not wise that they share the irq with the grafix FS device =). Most probably the irq conflict is causing this, you are right. Especially the graphics card should stay alone, even though there are lots of irq management systems (mean the ones in your board and OS). FS Now i dont know much at all about irq management if someone could tell me the FS comand to change an irq and which irq is free and available in my pc FS here is a cat /proc/interrupts : Unfortunately there is no command that can change irqs, as long as they asre not pnp etc. But even if they are, I never could get success in this. Why ? Because IRQ's are managed by boards more strictly in later systems. FS # cat /proc/interrupts FSCPU0 FS 0: 567487 XT-PIC timer FS 1: 3092 XT-PIC keyboard FS 2: 0 XT-PIC cascade IRQ 3 and 4 seems to be not used. These are the serial ports. If you dont use any of them,or both, shut them off from your bios. FS 5: 0 XT-PIC es1371 You are very lucky your sound card uses irq 5 (I could not manage that) Keep it like this. FS 7: 1 XT-PIC parport0 FS 8: 1 XT-PIC rtc FS 10: 4323 XT-PIC usb-uhci, usb-uhci, eth0 If you are not using any usb devices, shut your usb controllers from your bios. They dont screw things but it would be better. FS 11: 238652 XT-PIC bttv, nvidia I guess your tv card is in slot 1 of your board.

Actually irq 9 is not as fine as irq 5,10,11 etc. but I did not have any troubles using that. Usually boards assign irqs to pci slots, that is like pci slot 3 can only use irq 9 and the irq of the pci slot 6 (something like that). You can find info about this in your mobo's manual, though you dont need to waste your time.

Re: [newbie] IRQ`s
Thanx for the reply. I was now trying to do a few things : First my original setup : AGP = nvidia PCI1 = empty PCI2 = firewire PCI3 = soundblaster128 PCI4 = ethernet PCI5 = WinTV ISA = empty First i changed the tvcard wich was in the last pci slot (sharing with nvidia) to PCI slot1 below the AGP slot restarted my box and it was still sharing with nvidia damn . Then i took out the firewire card and put the tvcard into its slot (PCI2) After restarting the system it was not sharing anymore tvcard had irq9 and nvidia was alone on irq11 ... but it kept crashing the whole system so its not about the irq . So i have two questons : first how can it be that the agpslot shares with 2 different PCI slots and how can it be that i have 5 slots but i can only use 3 of them if i avoid sharing the agp`s irq? ( i need atleast 4 of them ) Second question is do you know anything about wintv cards and xawtv why could it be crashing my entire system it seems to be not nice at all.

[newbie] IRQ Problems after BIOS modifications
Hi to all, i had my Dual-Boot-System running. (windows 98 and Mandrake 7.0). I decided to make modifications in my BIOS to optimizes it. After that my Windows assigned the new IRQ to my Hardware, but Mandrake didn´t. Now i want to setup my internetconnection by ISDN, but whatever i do, Mandrake says that the device is busy. Now my question: Do i have to install Mandrake again or is there a chance to reset hardware settings in Mandrake?
