Field description

ataPBHdr

See the definition of the ataPBHdr parameter block.

ConfigSetting

This 32-bit field contains various device configuration information. In general is it used for features that might be device configurable but which might be know only at the ATA driver level. Bit 6 is the only bit used by ATA Manager 4.0 or later. The bits have the following definitions:

Bits 0-5:	Reserved, should be 0
Bit 6:	ATAPI packet DRQ handling setting. 0 = Check for assertion of cammand packet DRQ, this is the default setting. 1 = Check for interrupt DRQ command DRQ.
Bits 7-31:	Reserved, must be 0

ataPIOSpeedMode

This field indicates the device access speed value in PIO (polled I/O ) mode currently used for commands and PIO data transfers. This value can be modified with the ATA_SetDevConfig function. In parameter block versions 1 and 2, this field is an integer. In parameter block versions 3 and greater, this field is bit-significant, where the low-order bit indicates that PIO mode 0 is the current mode.

pcValid

This 16-bit field applies to systems that support PCMCIA card services. It indicates which of the PCMCIA unique fields contain valid information. The following values are defined:
bit 0 = when set, the value in the pcAccessMode field is valid
bit 1 = when set, the value in the pcVcc field is valid
bit 2 = when set, the value in the pcVpp1 field is valid
bit 3 = when set, the value in the pcVpp2 field is valid
bit 4 = when set, the value in the pcStatus field is valid
bit 5 = when set, the value in the pcPin field is valid
bit 6 = when set, the value in the pcCopy field is valid
bit 7 = when set, the value in the pcConfigIndex field is valid
bits 14-8 = reserved (set to 0)
bit 15 = reserved
The pcValid field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

PWMultipleCount

This field is reserved for future use. To ensure future compatibility, all reserved fields should be set to 0.

SectorsPerCylinder

This field is reserved for future use. To ensure future compatibility, all reserved fields should be set to 0.

Heads

This field is reserved for future use. To ensure future compatibility, all reserved fields should be set to 0.

SectorsPerTrack

This field is reserved for future use. To ensure future compatibility, all reserved fields should be set to 0.

socketNum

This field contains the socket number for the device used by the PCMCIA card services. The socket number is required to request card services. A value of 0xFF indicates the device is not a card services client. The socketNum field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

socketType

This field specifies the type of socket. The values are defined as:
00 = unknown socket type
01 = internal ATA bus ( kATASocketInternal)
02 = media bay socket ( kATASocketMB)
03 = PCMCIA socket ( kATASocketPCMCIA)

deviceType

This field specifies the type of device. The possible values are defined as:
00 = unknown or no device present ( kATADeviceUnknown)
01 = standard ATA device detected ( kATADeviceATA)
02 = ATAPI device detected ( kATADeviceATAPI)
03 = PCMCIA ATA device detected (the 03 value is not returned by ATA Manager 4.0 or later)

pcAccessMode

This field specifies the current mode of the socket. This field is valid only when bit 0 of the pcValid filed is set. The mode values are:
0 = I/O mode
1 = memory mode
The pcAccessMode field is not supported in ATA Manager 4.0 or later.

pcVcc

This field specifies the voltage on Vcc in tenths of a volt. The value in this field is only valid when bit 1 of the pcValid field is set. The pcVcc field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

pcVpp1

This field specifies the voltage of Vpp1 in tenths of a volt. The value in this field is valid only when bit 2 of the pcValid field is set. The pcVpp1 field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

pcVpp2

This field specifies the voltage of Vpp2 in tenths of a volt. The value in this field is valid only when bit 3 of the pccValid field is set. The pcVpp2 field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

pcStatus

This field specifies the current card register setting of a PCMCIA device. The value in this field is valid only when bit 4 of the pccValid field is set. The pcStatus field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

pcPin

This field specifies the current card pin register setting of a PCMCIA device. The value in this field is valid only when bit 5 of the pccValid field is set. The pcPin field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

pcCopy

This field specifies the current setting of the card socket/copy register of a PCMCIA device. The value in this field is valid only when bit 6 of the pccValid field is set. The pcCopy field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

pcConfigIndex

This field specifies the current setting of the card option register of a PCMCIA device. The value in this field is valid only when bit 7 of the pccValid field is set. The pcConfigIndex field is not supported in ATA Manager 4.0 or later, because the PC Card services are now handled by other system software.

ataSingleDMASpeed

This bit-significant field indicates which single word DMA mode, if any, is currently configured for use with DMA transfers. The intitial default value is single word DMA mode 0. The DMA transfer mode may be modified with the ATA_SetDevConfig function. This field is only valid for ATA Manager 3.0 or greater.

ataMultiDMASpeed

This bit-significant field indicates which multiword DMA mode, if any, is currently configured for use with DMA transfers. The intitial default value of this field is 0, which indicates that multiword DMA not selected. The DMA transfer mode may be modified by the ATA_SetDevConfig function. This field is only valid for ATA Manager 3.0 or greater.

ataPIOCycleTime

This word field specifies the minimum cycle time in microseconds of mode 3 or greater PIO transfers. For additional information about the contents of this field, see the ataPIOCycleTime field in the ATA_SetDevConfig function description.

The actual cycle time may be higher than this value if the system hardware is unable to create the requested cycle time while maintaining signal timing for the PIO mode in use. This field is only valid for ATA Manager 3.0 or greater.

ataMultiCycleTime

This word field specifies the minimum cycle time in microseconds of mode 1 or higher multiword DMA data transfers. For additional information about the contents of this field, see the ataMultiCycleTime field in the ATA_SetDevConfig function description.

The actual cycle time may be higher than this value if the system hardware is unable to create the requested cycle time while maintaining signal timing for the multiword DMA mode in use. This field is only valid for ATA Manager 3.0 or greater.
