I saw it's possible to Crossflash Sony DRU-865S to Liteon iHAS422, but... someone said he had Crossflashed an AD-7220 to Liteon iHA322 and should be possible to flash it to iHAS422 too... so my stupid question is;
is it possible to Crossflash the Sony to the Optiarc directly ???
same hardware/chip ??? seems to be possible
iHAS422 MT1859LL clones: AD-7221S, SONY DRU-865S, ASUS 22B1LT
So how to crossflash from SONY DRU-865S to AD-7221S ???
the purpose is to see if the Optiarc could be MacOS compatible...
like the AD-5260S or 7260S ...
is it possible to revert if not ???
Sony's one don't allow sleep on MacOS... firmware or hardware issue ?
