The improvements seem to have something to do with 52x and the eject button (limit or increase read speed?? - I thought it already read at 52x), CD-RW media recognition and support for InCD. Anyway, that's my take on the bad machine translation, you decide for yourself:
How are you. It is a LG Electronics DS enterprise department.
The GCC-4480B which is 52 attachments CD-ROM Drive the new firmware carries thu to become, it register. Firmware with use method is becoming the compression together with the Zip. Carries thu before doing, first to release a compression, it reads a READ ME.TXT file and after protecting life carries does thu.
Improvement point -
The Eject the CD-R media 52 attachment due to the button the CD-RW media recognition power reinforcement which becomes format with function and the InCD which it reads
the model: GCR-8521B pe before: 1.03
currently firmwares pe the bay carries thu does from below transfer 1.02.
Use OS:DOS
Confirm the model life of CD-ROM Drive certainly.
Thank you. Be joyful one day.
