￿Word 0: General Configuration

This field indicates the general characteristics of the device. When Word 0 of the Identify drive information is 848Ah then the device is a CompactFlash Storage Card and complies with the CFA specification and CFA command set. It is recommended that PCMCIA modes of operation report only the 848Ah value as they are always intended as removable devices.

Bits 15-0: CF Standard Configuration Value

Word 0 is 848Ah. This is the recommended value of Word 0.

Some operating systems require Bit 6 of Word 0 to be set to 1 (Non-removable device) to use the card as the root storage device. The Card must be the root storage device when a host completely replaces conventional disk storage with a CompactFlash Card in True IDE mode. To support this requirement and provide capability for any future removable media Cards, alternatehandling of Word 0 is permitted.

Bits 15-0: CF Preferred Alternate Configuration Values

044Ah: This is the alternate value of Word 0 turns on ATA device and turns off Removable Media and Removable Device while preserving all Retired bits in the word.

0040h: This is the alternate value of Word 0 turns on ATA device and turns off Removable Media and Removable Device while zeroing all Retired bits in the word

Bit 15-12: Configuration Flag

If bits 15:12 are set to 8h then Word 0 shall be 848Ah.

If bits 15:12 are set to 0h then Bits 11:0 are set using the definitions below and the Card is required to support for the CFA command set and report that in bit 2 of Word 83.

Bit 15:12 values other than 8h and 0h are prohibited.

Bits 11-8: Retired

These bits have retired ATA bit definitions. It is recommended that the value of these bits be either the preferred value of 0h or the value of 4h that preserves the corresponding bits from the 848Ah CF signature value.

Bit 7: Removable Media Device

If Bit 7 is set to 1, the Card contains media that can be removed during Card operation.

If Bit 7 is set to 0, the Card contains nonremovable media.

Bit 6: Not Removable Controller and/or Device

Alert! This bit will be considered for obsolescence in a future revision of this standard.

If Bit 6 is set to 1, the Card is intended to be nonremovable during operation.

If Bit 6 is set to 0, the Card is intended to be removable during operation.

Bits 5-0: Retired/Reserved

Alert! Bit 2 will be considered for definition in a future revision of this standard and shall be 0 at this time.

Bits 5-1 have retired ATA bit definitions. Bit 2 shall be 0.

Bit 0 is Reserved and shall be 0.

It is recommended that the value of bits 5-0 be either the preferred value of 00h or the value of 0Ah that preserves the corresponding bits from the 848Ah CF signature value.

￿Word 1: Default Number of Cylinders

This field contains the number of translated cylinders in the default translation mode. This value will be the
