I have a Packard Bell EASYNOTE E4710 laptop (bought in 2005). (Please do not send me links to their customer service).
I urgently need to replace the defective NEC ND-6500A (made in 2004) slimline internal drive so I bought a TEAC DW-224E-C59, HW/FW ver. 02/A.AC. The BIOS does not recognize the new drive, probably because the original NEC drive is configured as “master” and the new TEAC drive as “slave”.
Question 1: Can I replace the old drive with a new one without making any changes, in other words, which modern slimline DVD drive is compatible with NEC ND-6500A?
Question 2: Can I change the TEAC drive’s configuration to “master” by soldering pin 45 to pin 47 of the IDE interface as shown [here](http://www.packardbellweb.co.uk/hdd/installguide/50-pin ATAPI interface connector for laptop and slimeline cd.htm#CSEL_to_cable_select_one_)
Question 3: Is it possible to change the TEAC drive’s configuration to “master” by flashing the drive’s firmware (an easier option) and how to do it?
Question 4: Is there a way to check the mode (“master” or “slave”) of a slimdrive DVD when searching for a replacement?
