I have several Asus DVDRW drives that use the Mediatek B chipset and would like to crossflash them to Lite-On drives. I have done similar things years ago but have forgotten the exact procedure. I did some searching but found no complete info. When flashing my DRW-24B3LT B to a iHAS424 B GL18 do I need to check the box to update the boot code? It should would be nice if someone in the know would write a guide with the exact procedure needed to crossflash a drive. Better yet also how to flash back to the original drive if necessary.
