INTRQ Support by ISD-300
Does the ISD-300 support INTRQ (ATA interrupt request)?
No, the ISD-300 does not support INTRQ. The ISD-300 relies on polling to determine device status.
Please note that the ISD-300 is obsolete and the functional replacement is AT2LP. All the related collaterals of AT2LP can be found in the link here
