The only commands that may be overlapped are

For the READ DMA QUEUED and WRITE DMA QUEUED commands, the device may or may not perform a bus 
release. If the device is ready to complete the execution of the command, it may complete the command 
immediately. If the device is not ready to complete the execution of the command, the device may perform a bus 
release and complete the command via a service request.

Command queuing allows the host to issue concurrent commands to the same device. Only commands included in 
the overlapped feature set may be queued. If a queue exists when a non-queued command is received, the nonqueued 
command shall be aborted and the commands in the queue shall be discarded. The ending status shall be ABORT 
command and the results are indeterminate.

The maximum queue depth supported by a device is indicated in word 73 of Identify Device information.

A queued command shall have a Tag provided by the host in the Sector Count register to uniquely identify the 
command. When the device restores register parameters during the execution of the SERVICE command, this Tag 
shall be restored so that the host may identify the command for which status is being presented. If a queued 
command is issued with a Tag value that is identical to the Tag value for a command already in the queue, the entire 
queue is aborted including the new command. The ending status is ABORT command and the results are 
indeterminate. If any error occurs, the command queue is aborted.

When the device is ready to continue processing a bus released command and BSY and DRQ are both cleared to 
zero, the device requests service by setting SERV to one, setting a pending interrupt, and asserting INTRQ if 
selected and if nIEN is cleared to zero. SERV shall remain set until all commands ready for service have been 
serviced. The pending interrupt shall be cleared and INTRQ negated by a Status register read or a write to the 
Command register.

When the device is ready to continue processing a bus released command and BSY or DRQ is set to one (i.e., the 
device is processing another command on the bus), the device requests service by setting SERV to one. SERV shall 
remain set until all commands ready for service have been serviced. At command completion of the current 
command processing (i.e., when both BSY and DRQ are cleared to zero), the device shall process interrupt pending 
and INTRQ per the protocol for the command being completed. No additional interrupt shall occur due to other 
commands ready for service until after the SERV bit of the device has been cleared to zero.

When the device receives a new command while queued commands are ready for service, the device shall execute 
the new command and process interrupt pending and INTRQ per the protocol for the new command. If the queued 
commands ready for service still exist at command completion of this command, SERV remains set to one but no 
additional interrupt shall occur due to commands ready for service.

When queuing commands, the host shall disable interrupts via the nIEN bit before writing a new command to the 
Command register and may re-enable interrupts after writing the command. When reading status at command 
completion of a command, the host shall check the SERV bit since the SERV bit may be set because the device is 
ready for service associated with another queued command. The host receives no additional interrupt to indicate that 
a queued command is ready for service.
