Not having BSY and DRQ correct before asseting INTRQ is a clear violation of the ATA and ATA/ATAPI standard for about 10 years. But Pat, I think you misunderstand what INTRQ is and what it is used for... The ONLY purpose (in non QUEUED commands) of INTRQ is to signal the host that a device has set the BSY=0 and that the host should read the device status to see why it did that. INTRQ has NO other meaning. *** Hale Landis *** www.ata-atapi.com *** Subscribe/Unsubscribe instructions can be found at www.t13.org.
