Toshiba satelite a100-661 replace dvd drive

Hello,

i want to replace the combo drive with a dvd burner in my toshiba satelite a100-661.
Is this right that all nec slimline burners like 6750, 7550,7551 come with a firmware in master mode.
In this connection the most toshiba notebooks require a firmware in master mode and function without a firmware flash.
Can anybody confirm this.

regards

Usually NEC slimline drives are sold with master firmwares, but most (if not all) Toshiba laptops need a slave drive to work properly. But for the drives you mentioned, slave firmwares are available.
