A7N8X-E DELUXE MB & PCI SLOT USAGE
Hi Everyone,
Im after some helpful advice on which PCI slots I should use to avoid conflicts/IRQ sharing or which slot would be best to use for the following; 1/ 3Com 56K PCI Modem 2/ Soundblaster PCI Audigy Soundcard 3/ AGP Gfx Card On Page 2-12 of the MB user manual it shows a table of 'IRQ assignments for the motherboard' but I do not quite understand it. (I shall try to replicate it below - so I hope it renders ok) INT A INT B INT C INT D PCI Slot 1 shared - - - PCI Slot 2 - - - shared PCI slot 3 - - shared - PCI slot 4 - shared - - PCI slot 5 shared - - - AGP Slot - - - shared Serial ATA - - shared - Gigabit Lan - shared - - WiFi Slot shared - - - What does this mean? (is it if I put a card in PCI slot 1 , it will share the same interupt as slot 5 and the WiFi slot? All help greatfully received. Thanks |

It does not mean so much with windows xp, but it's a good reminder in order to keep Lan, agp and wifi (and probably sata) working on their separate irq. But I would think that pci1 is the one closest to agp. It is normal in older computers to avoid using the first pci slot, when agp is used. They normally shared irq. But here pci2 and agp are shared. best regards John |

Thanks If you have a modem, you could put it in slot4 and disable the Marvell Gigabit Lan. That would guve the modem an exclusive interrupt. You could put the SoundBlaster in Slot1 and leave Slot5 and the WiFi slot blank. That will give the SoundBlaster the highest priority slot (Slot 1 - nearest the processor), plus then it will have an exclusive interrupt. The table in the manual isn't always accurate, so you can check the IRQs assigned in Windows and see whether the cards in question, received the same IRQ as some other hardware. That could indicate the sharing table isn't what it seems. In any case, you only need to worry about the SoundBlaster, if the sound is being distorted (crackling etc). The most sensitive test I found, was listening to the Windows startup sound, just after the desktop appears. Since there is disk I/O happening at the time, that seems to be enough to uncover any problem the SoundBlaster might be having. HTH, Paul |

Read down the list (vertically)
I.E. Slot 1 shares with slot 5 and wifi slot. Slot 2 shares with AGP. Slot 3 shares with Serial ATA and Slot 4 shares with Gigabit LAN. If you're using XP it shouldn't really matter. Though I'd make sure I wasn't sharing anything with SATA if I was using SATA. If you are using XP, disable the feature in the BIOS that allows you to have extra virtual IRQs. I've found this feature to cause issues with sound cards stuttering etc..

Do you know what option this is in this motherboard's BIOS? (A7N8X-E Deluxe)

Stick to the normal IRQ paradigm Sorry, I have the non-E version. Manual is on the missing list. I think it was something like APSIC, APIC ASPC or something like that. You have to do it BEFORE you install XP. If you change it AFTER you've installed XP you may not be able to boot unless you change it back again. Regards, Thomas WARNING!

You've already been given good advice and comments by the others...
I am curious as to why you'd want to use an Audigy soundcard on a MB with nVidia Soundstorm Sound? Soundstorm is really an excellent sound chip, not your typical crap integrated stuff. It can actually do Dolby Digital 5.1 encoding on the fly, something no other consumer sound chip is capable of at this time. "Sgt_Wilson" wrote in message ...
