LTR-52246S won't burn if DMA enable but will off

Hello…my LTR-52246S won’t burn ( “communication failure” in log ) if DMA is checked but will burn fine if DMA is left unchecked in CD-RW settings in device manager. I am using Windows 98se and ms-6580 v2.0 motherboard which has the intel 845GE Max chipset. It is residing on my secondary Ide controller as master with a slave HD present.

Any help would be much appreciated.
