About a week ago, several updated firmwares could be found on Optiarc’s website. But there were not only updates for Optiarc branded desktop drives but also some firmwares for older NEC drives which have not appeared on NEC’s own site so far although they seem to have been compiled some months ago already.
All these firmwares can be found along with bitsetting and RPC1 patches on our site. In detail you can find updates for the NEC ND-3551A (version 2.03), NEC ND-3571A (version 2.11), NEC ND-4551A (version 1-09), Optiarc AD-5170A (version 1.13), Optiarc AD-5170S (version 1.12), Optiarc AD-7170A (version 1.04), Optiarc AD-7170S (version 1.02), Optiarc AD-7173A (version 1-03) and Optiarc AD-7173S (version 1-02).
Please note that only the 4551A, 7170A and 7173A firmwares have been tested by us.
