SCSI controller-HD questions

I'm somewhat new to SCSI, so bear with me.

I have Adaptec's SCSI Card 29160N (PCI) installed with the 68 pin LVD cable in a WIN98 SE machine with (2) 18.2 GB Compaq 7200 RPM Wide Ultra 2 SCSI HD's installed on 1 channel, installed in a clone C500-256MB RAM-Diamond Monster Fusion 16 MB AGP video-Standard PCI sound card and 56K modem with a Compaq 3120 NIC and a IDE 13.6 GB HD (disconnected for now). The Adaptec's SCSI Card and SCSI HD's are hooked up and functional, with WIN 98 on Drive 0, and nothing on Drive 1, and boots to Win 98 fine.

My questions;

1) Can I use the IDE drive with the SCSI controller/HD's, and how do you set that up?

*2) I got the HD's used without documentation, so what do all the jumpers on the non-power/cable side mean, and where should they be set (on both hd's). (ID0, ID1, ID2, ID3, WRIT PROT, START CMD, SINGLE/WIDE, DIFFSENS, SP SYNC, IDD RESET , LED, TERM PWR EN)?

*It came with a jumper on START CMD on both, so that's where I left it

3) What kind of throughput should I get vs. IDE, mimimum, and how do I test that?

As I said, the controller works fine, see's the HD's in the SCSI BIOS, and boots to WIN98 SE OK, but the drives seem VERY warm, and really not that fast.

Did I screw up, miss a setting, etc. Any help would sure be appreciated.

Thanks all.

1. Yes, just plug the IDE HD in, and set your BIOS to boot from SCSI (so that you can still boot your win98 installation).

2. Every device on a SCSI bus needs to have a unique identifier. If you are seeing both drives now, that means they already have unique ID's. You should make a note of what they are, because when you add other SCSI devices to the bus later, you'll need to assign them non-conflicting ID's. This is what the ID0/ID1/ID2/ID3 jumpers are for. WRIT PROT is probably "Write protect" (e.g. disallow writes to the drive). I can't recall offhand what the others do. I'm sure there are docs to just about any drive you could imagine on the net somewhere...

3. Tools to measure drive performance: HDTACH, sisoft's Sandra, and winbench.

Once you've run your tests, post your numbers, and I'm sure people who have similar setups to yours will confirm your numbers.
