Can an IDE hard drive be added to a PC that boots to a SCSI hard drive?

I have an IBM Intellistation PC with a SCSI hard drive.  Is it possible to add an IDE hard drive to this system?  I have tried hooking up the new IDE drive in various ways but the PC seems to recognize the SCSI or the IDE but not both.  I want to continue to boot up to the SCSI drive.

Well you should be able to.
The CD-ROM is probably IDE and it is recognized.

Does it show up in the BIOS page ?
Is the drive formatted ?
Can you see it in the DOS Fdisk program ? ( see for bootable floppies and utilities ).

Did you check that IDE interface is turned on in the BIOS ?

I hope this helps !
Good advice above !
What is the disk Size ?
How is the disk connected? on the same cable as the cd? then check the jumper settings : 1 master, 1 slave.
check also that the ide cable is not turned around (could be on older cables)
Do not forget to power the drive   :-))
and is the disk recognised properly in the bios? good size? some bioses do not recognise disk sizes over 128 GB

Thank you for the good ideas to check.  I won't be able to check the PC until 8 hours from now.   I don't think it showed up on the BIOS page but I will check.  I remember seeing some settings for IDE in the BIOS and I tried a few things there but I wasn't sure what I was doing.  When I get to the PC I will write down anything in the BIOS about IDE and ask about it here.
The hard drive size is 40 GB.  I did not think it was formatted, but, when it boots to just the new hard drive it does go to a c: prompt, so maybe it is formatted for FAT32 and that is why XP doesn't recognize it?   Can I format it with the XP install CD?    I tried connecting the drive in the middle of the cable going to the CD and then I also tried unplugging the CD and connecting the drive to the end of the cable.  I think I have another IDE slot on the motherboard, maybe I should buy a new cable and plug it in there.  I connected the number -1- on the drive with the red stripe on the cable.  I will try the jumpers at Master, Slave and Cable select.  I did connect the power but I do appreciate the advice about that, because sometimes the problem is some little thing like that.

Your BIOS will also determine the boot order - or which drive is the default for booting.

Your CD is probably set to  master ( Check the jumper on the BAck.)
If it is the new drive should be set to Slave.

If the CD is set to CS ( cable select ) then your 40 GB drive should be also.

XP will definitely recognize all versions of FAt formats.

I hope this helps !
>>  when it boots to just the new hard drive it does go to a c: prompt, so maybe it is formatted for FAT32 and that is why XP doesn't recognize it?    << this means it is formatted, probably with FAT32 as you suppose and the sytem files are on it (otherwise it would not boot to the C: prompt - BUT - XP should recognise it, no reason why not
>>   Can I format it with the XP install CD?  << yes, you can; during the install process, it will show you the partitions; just delete them if you want to install XP and follow the screens

The IDE drive is formatted FAT32.  I have, of course the SCSI drive and I also have a CD and a CDRW.  The CD and the CDRW are each connected to the end of a cable, one of them is connected to  the primary IDE cable and the other is on the secondary IDE cable.  If I plug the IDE drive into the middle of either cable and set the jumper to either Slave or CS it will either boot up to the SCSI drive and not recognize the IDE drive, or it will boot to the IDE drive and not recognize the SCSI drive.  Any ideas?  I will try connecting the IDE on the end of the cable, by itself and see if that helps but I think I already tried that.
You should in bios 2 sections of boot sequence, one of them is to set something like "boot from system bios ..." which means system will boot from IDE hard drive first. Use key + / - or page up/down to change the scsi drive at first one to boot. Other boot sequence is like floppy > cdrom > hard drive, etc. or something like that, leave them alone.

Thank you all very much for helping me.  I just found the answer at this website:
The answer is below, see url for complete details.
Diagnosis: Unfortunately, there is no resolution to this problem in many cases. IDE/ATA hard disks are natively supported by the BIOS on most PCs, while SCSI hard disks are not. For this reason, the BIOS is programmed to look first for IDE hard disks and boot them if any are found. The SCSI drives are not looked at until afterward. There are now some newer motherboards (namely the Asus boards) that have a BIOS that will allow you to select booting from SCSI ahead of IDE on a system that has both. Most motherboards do not allow this.
My BIOS settings do not allow me to boot to the SCSI when I have the IDE in.  I found a BIOS update but it does not have any changes that remedy this problem.
I think thaere may be a small program ( bootb) that allows tou to rediect the boot to any drive, so that it strts from the IDE, but actually boots the SCSI.

You will need to search for a modern version ( originally designed for dual floppy drives), but it is a definite option.

That is interesting! depending bios and hardware built-in onboard, and like server type PC's that have scsi built-in onboard, there is option to boot from scsi drive. For example, the boot device and boot sequence like this:
Boot from device
- Boot from system bios
- Boot from Fujitsu scsi drive
- Boot from Seagate scsi drive
Boot sequence:
- Floppy disk
- IDE hard drive
Such boot option, you will able to boot from IDE hard drive no matter of what scsi drives existing in system.

I think your bios limited and might be needed to upgrade if there is available such support from IBM.
