M-Audio Dman PCI Инструкция по эксплуатации онлайн [16/29] 18973

If PnP has chosen an IRQ for the DMAN PCI that is being shared with another

device, there might be a device conflict. If the DMAN PCI is sharing an IRQ

with an entry named “IRQ Holder for PCI Steering,” that is normal and should

function properly. If the DMAN PCI is sharing an IRQ with another PCI

device (such as a USB Host Controller), it might also do so without problems

since the DMAN PCI is capable of sharing an IRQ with many other PCI prod-

ucts. However, IRQ’s are rarely shareable between ISA devices that are not

PnP-compliant and other cards. If this is the case one of the devices will have

to be manually adjusted to use another IRQ.

NOTE: When resolving conflicts between PnP and non-PnP devices, it is

usually easier to readjust the resource settings of the non-PnP device.

Windows is only aware of the resource settings of the installed PnP devices

and has no information available to it for adjusting the PnP devices around

the non-PnP devices. The exception to this is when a non-PnP device has a

true Windows 98/95 driver written for it, or if the BIOS allows instructions

for an IRQ to receive a legacy device as opposed to a PnP device. In that case

Windows is aware of the non-PnP device’s resource requirements.

If you ever need to change the DMAN PCI card’s IRQ, the easiest way is to

move the DMAN PCI to another available PCI slot. This will cause the system

to recognize it again as new hardware and establish it with another IRQ. Some

newer BIOS’s (see your computer manual) allow the selection of an IRQ for

each PCI slot on the motherboard. This can be very handy in resolving IRQ

assignments for PCI devices. However, if there are no IRQs available, some

kind of reconfiguring or reprioritizing your system may be required. See the

“Troubleshooting” guide for more info. Also, a second hardware configuration

can be created for running two sets of hardware profiles. See your Windows

documentation for help in this area.

As mentioned earlier, the Computer Properties list is the best source of infor-

mation to establish availability of resources. Clicking the Input/Output (I/O)

button at the top of the box will give you a list of Addresses in use (as well as

DMA channels, although none are used by the DMAN PCI). Usually, there are

not address conflicts between PnP devices, but one might note that an address

of 300h (the default address of the WINMAN 4x4/S, for instance), will read

“0300” in this list (it is a 16-bit hexadecimal representation).
