I have a Panasonic (Matsushita) SW-5583 BD. I bought it in early 2008 with firmware version 1.00. I recently had problems playing the Iron Man BD, and thought it might be good to check for a FW update. Naturally, I cannot find it at Panasonic's website, but I did find version 1.03 at 121ware. It is in chinese, but the FW file is at the bottom.
The BD drive is connected to an Intel IHC9R RAID port. I have the RAID set to disabled in the BIOS, however I still get the message "Target drive is not connected". I would think the SATA port would function normally with RAID disabled. I know I can't boot from the BD drive with it set to AHCI or RAID, but it will boot when set to 'disabled'. Shouldn't this work OK?
Has anybody had any luck updating the firmware on this drive?
