Download Firmware NEC ND-2500A 1.07 9a beta

Hermanvh has on the forum of The Firmware Page a new hacked firmware for the NEC ND-2500A DVD burners posted† This time it concerns beta version 9a and is based on the HP 1.24 firmware. This firmware makes it possible to change the bit setting and book type of a DVD-R and DVD+R disc. Version 9a beta is for both Windows if DOS available and has the following release notes:

I just worked on Beta 9a of the booktype firmware. This version is based on HP 420i 1.24 firmware I implemented the +R writing strategies from the 1.06 NEC 2500A firmware.

Problem with Beta 9 causing “Power Calibration Error” on all DVD-R media at all speeds should be solved now

The problems with most DVD-R’s which should work @ 8x only working @ 6x should be fixed now! Most common 4x DVD+Rs and 4x DVD-Rs should work @ 8x now!

For DVD-R the FUJIFILM03 strategy is used, for DVD+R the PHILIPS 081 strategy!

Added support for the following discs:
MCI4XG01 4x DVD-R @ 8x
OPTODISCOR8 8x DVD+R @ 8x
OPTODISCOP4 4x DVD+RW @ 4x
OPTODISCK001 4x DVD-R @ 8x
OPTODISC04 4x DVD-R @ 8x

I also added a version identifier after several requests
