MISCELLANEOUS TECHNICAL NOTES

When using this controller, the system will see the drives attached to each connector as a single drive. i.e.: if you have two 100MB drives attached to CN1 the system will see one 200MB drive. However, if have two drives you would like to be recognize individually, you may attach one to CN1 and the other to CN2. Closing Jumpers JDR0 and JDR1, which shorts the resistors on the IDE buses, helps to eliminate drive incompatibility caused by different noise filtration methods. This controller supports 256KB, 1MB, or 4MB fast page mode SIMM's, 80nsec or faster. At least one bank must be filled for proper operation.
