Home / I-Opener Areas / I-Opener Technical Stuff External IDE cd rom as slave Help!

External IDE cd rom as slave (modified 0 times) newb2003 Profile I'm having a bizarre problem, and was wondering if anyone else has experienced this. I have a V5, with upgraded BIOS and 2.5 to 3.5 IDE converter from Badflash, running to an external 3.5 in IDE drive and an external cd-rom drive. When I connect the devices individually, the BIOS recognizes each one, and they appear to function normally. With Smartboot, I can even boot from cd rom. The problem is that when I connect them both on the same IDE cable, the cd rom always gets bumped off of the chain. The BIOS recognizes the HD and the Sandisk, but not the cd rom. I've tried all of the jumper settings on both the HD and the cd-rom to no avail. Do I have to disable the Sandisk in BIOS? I've even tried a different cd rom that I know is ok, and it's giving me the same problem. Is there any sort of special BIOS setting to bump the Sandisk, and keep the cd rom as slave? Thanks for any help. 10-24-2002 06:22:35

RE:External IDE cd rom as slave (modified 0 times) Lincoln_man Profile The IO only has a single channel IDE chip (ie, only two devices). The scandisk has to be physcially disabled or removed to see two external drives. Any setting in the bios won't do it. Search the BBS, this has been done before. 10-24-2002 12:40:37

RE:External IDE cd rom as slave (modified 0 times) patcat88 Profile One thing. How are you powering the 3.5 drive? I heard that the you can't power a 3.5 drive off the ide cable. 10-25-2002 06:40:37

RE:External IDE cd rom as slave (modified 1 times) newb2003 Profile You are correct, I have an external SCSI-Hacked-to-IDE drive box with it's own power supply. This power supply is split between the cd-rom and the 3.5" HD (Master device). I also sent this question to Badflash, and the answer that I got back was that the CD-ROM has to "overpower" the Sandisk chip in the IDE chain, and that the older cd roms were better at this. I also found some material on this BBS stating that if you disable the (Drive 2)Sandisk chip in the BIOS that Win98SE will still pick up the CD drive in the drive list. You just won't be able to boot from CD. I could live with that. I'm hoping that Linux Mandrake works the same way. I'll post my findings. 10-25-2002 09:57:10
