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. Use a boot disk with only the IDE drive installed, run f-disk and set the primary partion to non-active. However, if you have the BIOS set up to boot from SCSI first, this won't make a difference, it will just boot from the SCSI drive regardless of what IDE stuff you have installed.

2.)
ID0,ID1,ID2ID3 = This is where you set the SCSI ID. Each drive on the SCSI controller - the "Chain" - needs to be assigned it's own individual ID's. Controllers are generally 0 or 7, so best avoid those. If you want to use an ID above 3 just add the value - for 4, just put a jumper on ID1 and ID3. ID1 + ID3 = ID4. Easy.

WRIT PROT = Write Protect the Drive.

SINGLE/WIDE = This limits the drive to Ultra SCSI speed, 10MB per second. Handy if you think you might be getting cable problems, as Ultra is a bit less picky about cables.

LED = You can connect the hard drive LED directly to it.

SP SYNC = No Idea.

START CMD = No Idea.

DIFFSENS = No Idea.

IDD RESET = No Idea.

TERM PWR EN = Enables SCSI termination on that drive.

3.) No idea. Should be slightly faster, but there won't be any CPU hit under high load.

The temperature is fine, SCSI Drives of that generation tended towards hot.

My Advice: If the set-up works, Leave it.
