.Sh NAME
.Nm hv_ata_pci_disengage
.Nd Hyper-V ATA PCI Disengage driver
.Sh SYNOPSIS
To compile this driver into the kernel, place the following lines in
the system kernel configuration file:
.Bd -ragged -offset indent
.Cd "device hyperv"
.Ed
.Sh DESCRIPTION
The
.Nm
driver prevents the native
.Fx
ATA driver from
loading in the presence of Hyper-V.
.Fx
guests running on Hyper-V can take advantage of the Hyper-V Storage
Virtual Consumer
.Pq Xr hv_storvsc 4
for using their IDE devices.
Since the ATA
driver serves IDE devices as well, there is a chance that the ATA driver may
interfere with the operations of
.Xr hv_storvsc 4 .
The
.Nm
driver avoids
conflicts between the ATA driver and
.Xr hv_storvsc 4
by disabling the ATA driver
when the
.Fx
guest is booting.
.Pp
A side effect of disabling the ATA driver is that CDROM may become
inoperational on
.Fx
guest partitions.
If CDROM access is a must then users may use
"set hw.ata.disk_enable=1" at boot time to prevent the ATA driver from being
disabled.
