tried to flash my 8400B (40x) to 8520 (52x). MTKWinFlash told me that everything worked fine. But during rebooting, my BIOS doesn’t find the drive anymore. It says “NON ATAPI COMPATIBLE DRIVE”.
The CDR is Secondary Slave…
In order to get it back to 40x I used the “normal” Firmware and it works properly. But I’d like to have a 48x or 50x CDR without buying one.
