ATA Security
ATA Security is supported via ATACB commands, the same method used by the ISD-300LP.
ATACB commands are not supported by the major operating system drivers so the Cypress
driver must be used to support ATA Security. BIOS authors can find the entire ATACB
description in the datasheet.
IDE hard drives will only prompt for the password on a hard reset. If the SKIP_PIN_RESET
bit is set in the EEPROM, the device will ask for a password only on initial power-up. If the
SKIP_PIN_RESET bit is cleared, the device will ask for a password when it is unplugged from
the host or when the host is power-cycled.
