// IDE.C - IDE Disk driver
// written by Rex Jolliff
// with help from various documentation sources and a few peeks at
// linux and freebsd sources.
//
// This driver supports up to 4 controllers with up to 2 drives each.
// The device names are assigned as follows:
// \Devices\HarddiskX\Partition0
// for the raw device, and
// \Devices\HarddiskX\PartitionY
// for partitions
// where:
// X is computed by counting the available drives from the following
// sequence: the controller number (0=0x1f0, 1=0x170, 2=0x1e8,
// 3=0x168) * 2 plus the drive number (0,1)
// Y is the partition number
//
// The driver exports the following function:
//
// DriverEntry() - NT device driver initialization routine
//
// And the following functions are exported implicitly:
//
// IDEStartIo() - called to start an I/O request packet
// IDEDispatchOpenClose() - Called to open/close the device. a NOOP
// IDEDispatchReadWrite() - Called to read/write the device.
// IDEDispatchQueryInformation() - Called to get device information
// IDEDispatchSetInformation() - Called to set device information
// IDEDispatchDeviceControl() - Called to execute device control requests
//
// Modification History:
// 05/25/98 RJJ Created.
// 05/30/98 RJJ Removed IRQ handler and inserted busy waits
// just to get something working...
// 07/18/98 RJJ Made drastic changes so that the driver
// resembles a WinNT driver.
// 08/05/98 RJJ Changed to .C extension
// 09/19/98 RJJ First release (run for cover!)
//
// Test List:
// 09/17/98 RJJ Pri/MST: 14.12X19 WDC AC31000H Test Passed
// Pri/SLV: None.
//
//
// To Do:
// FIXME: a timer should be used to watch for device timeouts and errors
// FIXME: errors should be retried
// FIXME: a drive reset/recalibrate should be attempted if errors occur
// FIXME: Use DMA for transfers if drives support it
// FIXME: should we support unloading of this driver???
