yo! thanks man! I went rummaging into my pile of useless stuff and found one unused IDE cable, fresh from the plastic bag.
it appeared that the problem lies in one of the connectors, so thats why the master dvd-drive works just fine. but there is also another problem: the cd-rw drive lost one of its jumper… so the bios cannot determine which one is the slave or master. then i took one of the jumpers from one of my unused hdd, and it works like a charm, lol
but still, after looking around in the forum trying to find the firmware, it appeared that the TS0W firmware from the liteon LTR-16101B is better than the default TYS7 firmware from this drive… so if anyone has the binary for the TS0W, can u send it to me?
EDIT: after double-checking, it appeared that my firmware is TYS3, so can anyone also give me TYS7?
