These are very standard DMA settings. Take a look at your IRQ list,
which numbers from 00 - 15 (in most cases). Your PCI modem is probally
sharing an IRQ. Since you're using a PCI modem and Win98SE it may be
best to remove the device and drivers, then reinstall to another PCI
slot.
Generally, I would install a PNP modem in the slot furthest from the
processor to net a low IRQ on most Win98SE systems. Sound card next,
then network card or other, and top off with video. The further a PCI
slot is from the processor the higher the impedance. Consequentially,
you would then place your high priority devices such as video closest
(such as PCI 01).
On the newer PIII/Win98SE based systems this method has worked conflict
free and (sometimes) greatly improved network and modem performance.
Just a recap of the above for visual purposes.
IRQ STATUS DEVICE
11 AGP Video AGP
shared slot PCI Video or Accelerator PCI01
10 PCI Network Card or Other PCI02
5 & 9 PCI Sound Card PCI03
3 PCI Modem PCI04
If you have built in sound, video, etc. IRQ's may have to be reserved
in BIOS to acquire the favorites.
Please note the above is an example of what I personally consider ideal
and may vary greatly depending on your configuration. Also, some
motherboards do not use PCI01 as the head of the bussing chain. Shared
slots is another issue that varies dependinding on the board.
The main point to emphasize is to install devices based on access
priority whenever possible.
Woops, didn't mean to get so deep rooted with the topic.
Hope some of this helps resolve your modem problem.
