Im sorry for bringging this topic again. I just bought the ASUS P5GD2 deluxe motherboard and having the same problem. I have two IDE HDD and a LG-GSA-H1OA dvd drive.
This motherboard only have one PRI-IDE slot and two ITE-IDE(PRI & SEC)(red color).The bios didnt detect my HDD as primary or secondary drive but it shows up in the boot priority option. But if i connect these drive to the one PRI-IDE slot, it will detect. So I connected my HDD and DVDdrive to the IDE slot, as master and slave. But when this two drive are connected, the DVD reads any disc very slow. Sometimes it just hangs.
I am trying to install windowsXP. I also tried booting with other bootable disc, same thing, very slow and somtimes just hang. But if i disconnect the HDD, the cd@dvd boot up normally. So I dont know how can I install the OS if I cannot connect the HDD.. I checked all the jumpers, tried other cables, 80pins 40pins... Is it my HDD or cable or the BIOS or other things? any suggestion is really appriciated.
