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 device 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 device in True IDE mode. To support this requirement and provide capability for any future
removable media Cards, alternate handling of Word 0 is permitted.
Bits 15-0: CF Preferred Alternate Configuration Values 044Ah: This is the alternate value of Word 0 turns on
