The drive supports an EEPROM Vendor Specific Page that enables an initiator to modify savable
parameters. Only one savable parameter can be changed per MODE SELECT command.
Figure 4-56. EEPROM Vendor Specific MODE SELECT Page — Data Format
The ASCII string has a parameter name followed by one or more space characters, a parameter value,
and an ASCII line feed or null character. When the string is parsed, the parameter value is interpreted
as shown in the following table. Note that the parameter name may be in upper or lower case. The
drive saves the savable parameters during resets and power cycles.
