Firmware
The firmware contains set instructions
for the operation of the drive. Functions such as: ejecting the
tray, reporting error blink codes, and servo motor control. During
the write process, the firmware plays a key part in controlling
the quality of the write. When a blank disc is placed in the drive.
The media's ATIP (Absolute Time
In Pregroove) is read to find out the manufacturer's specifications
such as the dye used on the media. Using the manufacturer's write
strategy for supported media is a much more accurate way to set
the laser power than relying solely on the OPC
return information.
This is just one of many benefits
with using Plextor drives. Plextor custom designs and develops its
own firmware, printed circuit boards (PCB), and servos for each
of our drives. This allows us to have a wider range of control over
our firmware, and allows us to constantly update our media
compatibility list with newer write strategies. That is why
it is generally recommended to keep your firmware up to date.
Firmware
Flash PROM
All
Plextor CD-RW and 40 Max CD-ROM drives use a Flash PROM (EEPROM,
or Electrically Erasable PROM), which can be upgraded by downloading
a firmware upgrade file and simply executing the file through
Windows.
The
UltraPlex 32 Max uses an EPROM (Erasable PROM programmed by using
ultraviolet light). The firmware upgrade for this drive is accomplished
by physically replacing the Firmware chip with a later version chip.
