|With ISA sound cards there were three setting that needed to be set with jumpers on the sounds card. Base address, Interrupt No and DMA No.|
The Driver also had to be configured with these same settings. If there were a mismatch between what the jumpers where set for and what the software was looking for then there were problems.. Plug n Play was still a few years away. Often failure to install ISA hardware was down to a misplaced jumpers as it was very easy to get it wrong.
220 is the standard base address although that could be changed. Sounds Cards usually used Interrupt 5 and 1 for the DMA address. Depending on what other hardware was installed there was often a conflict with Interrupt 5 so there were jumper options for different interrupts. There were no shared interrupts with the ISA bus.
