Abit SH6, P3-600, 256MB, Win 98SE, two HD's on IDE1, UDMA66, and two CD's on IDE2. One CD is a burner.
Here is the problem. One of my programs is TC2000, which needs the CD inserted to be active. I assume it is being used in a DMA mode. At any rate, TC2000 loads and never sees the CD. The board is new, so is the CD burner.
When I go to Control Panel/System/Device Manager (by type), under System Devices is shown TWO direct memory access controllers with one highlighted with the exclamation point. Clicking on that one gives the following:
General Tab status:
"The VDMAD.VXD device loader(s) for the device could not load the device driver. (Code2.)"
Settings Tab:
1. Reserve DMA buffer - checked
2. Address restriction - unchecked
Resources Tab:
1. Auto settings - checked
2. Resource type window shows numerous address conflicts "with [presumably the other] direct memory access controller."
The other controller is fine, shows the addresses conflicting with the sad one.
So, what do I do? Is there really two Direct Memory Access controllers, one for each IDE channel, or what? Note that this occurs whether or not the IDE2 connector is plugged or empty (nothing connected). How do I check for IRQ conflicts? Can I manually alter the Resource type window address conflicts?
Anybody have ideas? Need to know more?
Thanks in advance,
Bob
