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.
