However, as explained in the main text, you can disable Asus VIA Standard PCI to ISA Bridge USB pairs, either in Windows or in the BIOS, and either return their IRQ to the pool if they aren't sharing with a card slotor give yourself another slot with a unique interrupt choice if they are. Each of these is normally allocated an IRQ, but if you don't have anything plugged it to any of them you can disable them, and the system IRQs they use by default will become available to other devices, including the various PCI slots.

The important thing to remember is that you can't override any IRQ sharing that's determined by your motherboard's Interrupt Request Table, since these are choices hard-wired at the design stage. These can be found on multi-processor motherboards, and on some single-processor ones as well.


If you have one of these, and are running Windows or XP, then if you run in ACPI mode you'll get 24 interrupts rather than the 16 offered Asus VIA Standard PCI to ISA Bridge running under Standard mode, which can make other choices rather simpler. I've installed my Yamaha SWXG soundcard in slot 2, since this doesn't share with anything, but the worst decision for my soundcard would be slot 3, since as I explained in SOS Decembersharing with a USB Host Controller that polls its interrupts at a high rate would undoubtedly give my system a small performance hit and possible conflicts.

However, remember that you don't have to use every device on your system. By plugging the modem and printer into USB ports 3 and 4 and then disabling these ports inside my music partitions using Window's Device Manager, I could set the machine up so that PCI slot 3 wouldn't be sharing either, and it would become another possible home for a soundcard; also, the MIDI timing of my interface might benefit from not sharing an interrupt with anything else at the hardware level.

Slot 4 would be fine as long as I didn't install the CNR LAN board option, while slot 5 would also be suitable if slot 1 were still unoccupied, and slot 6 is once again fine in the absence of the on-board sound chip. Asus VIA Standard PCI to ISA Bridge

Out of interest, I did have problems installing one review soundcard in slot 5 while my Mia was sharing with it, but it worked perfectly once I'd moved it to slot 6. As long as the supplied Interrupt Request Table in your motherboard manual is correct, you just need to proceed logically and carefully when deciding where your soundcard s should live. I have come across some users claiming a few errors in the past, often when new versions of existing motherboards are introduced and the table in the printed manual isn't similarly updated.

For this reason it's well worth downloading the PDF version of the manual that specifically relates to your revision of motherboard. Of course it gets more complicated once you have lots of other PCI cards to install, but often a trip to an Internet forum that specialises in your make of motherboard will provide plenty of suggestions and examples from existing users who have already thrashed out the best options for their system.


However, there's no substitute for understanding the options for yourself, since you're almost guaranteed to have a different selection of cohabiting expansion cards. The most important thing if your PC is well stuffed with expansion cards is to make sure that any that do end up sharing are happy to do so. I'm not only Asus VIA Standard PCI to ISA Bridge to soundcard sharing problems either, since other types of card may have problems sharing with each other. I came across a reference to Adaptec's popular UW SCSI Controller card being unable to share, for instance, and trying to get it to do so may prevent your PC from booting up at all.

They will be dealt with when the current delayed transaction is completed. If two initiators attempt the same transaction, a delayed transaction begun by one may have its result delivered to the other; this is harmless.

The latter should never happen in normal operation, but it Asus VIA Standard PCI to ISA Bridge a deadlock of the whole bus if one initiator is reset or malfunctions. The PCI standard permits multiple independent PCI buses to be connected by bus bridges that will forward operations on one bus to another when required. Generally, when a bus bridge sees a transaction on one bus that must be forwarded to the other, the original transaction must wait until the forwarded transaction completes before a result is ready.

One notable exception occurs in the case of memory writes. Here, the bridge may record the write data internally if it has room and signal completion of the write before the forwarded write has completed. Or, indeed, before it has begun.

Such "sent but not yet arrived" writes are referred to as "posted writes", by analogy with a postal mail message. Although they offer great opportunity for performance gains, the rules governing what is permissible are somewhat intricate.

The PCI standard permits bus bridges to convert multiple bus transactions into one larger transaction under certain situations. This can improve the efficiency of the PCI bus. There are two additional arbitration signals REQ and GNT which are used to obtain permission to initiate a transaction.

All are active-lowmeaning that the active or asserted state is a low voltage. Pull-up resistors on the motherboard ensure they will remain high inactive or deasserted if not driven by any device, but the PCI bus does not depend on the resistors to change the signal level; all devices drive the signals high for one cycle before ceasing to drive the signals. All PCI bus signals are sampled on the Asus VIA Standard PCI to ISA Bridge edge of the clock. Signals nominally change on the falling edge of the clock, giving each PCI device approximately one half a clock cycle to decide how to respond to the signals it observed on the rising edge, and one half a clock cycle to transmit its response to the other device.
