I recently replaced my dvd-rom drive with a sparkly new DW-Q520A DVD-RW on my tosh laptop.
Since the drive has been installed, the laptop will display a IDE #1 Error message on restart.
Doing some investigation on this forum i’ve worked out its a master/slave problem on the drive firmware (HYS2)
http://codeguys.rpc1.org/utilities/E2MS_WIN_DW-Q520A.rar but problem persists
http://codeguys.rpc1.org/utilities/slim_master-slave.rar says the drive isbt this type.
Any more suggestions?
(PS EEPROM Utility 3.8.3 does not recognise the HYS2.BIN file format)
