Mixing PATA and SATA optical drives When mixing PATA and SATA optical drives in a workstation, the system first detects the PATA optical drive. For example, if the first optical drive is a SATA drive and second optical drive is a PATA drive, then the system detects the PATA optical drive first. This detection order results in the PATA optical drive being assigned the lower drive ID or drive letter by the operating system. FailSafe Boot Block BIOS recovery SATA optical drives are not supported for a Boot Block ROM Flash. One of the following alternatives must be used: • Use a floppy drive or PATA (ATAPI) optical drive. • Use a USB Disk On Key for xw6400, xw8400, and xw9400 workstations.

Mixing PATA and SATA optical drives
When mixing PATA and SATA optical drives in a workstation, the system first detects the PATA optical
drive. For example, if the first optical drive is a SATA drive and second optical drive is a PATA drive,
then the system detects the PATA optical drive first. This detection order results in the PATA optical
drive being assigned the lower drive ID or drive letter by the operating system.
FailSafe Boot Block BIOS recovery
SATA optical drives are not supported for a Boot Block ROM Flash. One of the following alternatives
must be used:
•
Use a floppy drive or PATA (ATAPI) optical drive.
•

DLA
In combined mode, oakcdrom.sys detects and addresses the SATA optical disc drive so that
