IDE RAID & SCSI Card in same box

I have an Iwill KK266-R (AMI RAID chip). Can I use both my IDE RAID & SCSI at the same time? Also I don't know if if makes a difference, but I will be booting off my SCSI drive.
 
I can't speak for that particular board, but my Soyo Dragon Plus manual specifically mentions the possibility of a SCSI card coexisting with the onboard IDE RAID. Look at the boot order section of your BIOS - mine has a selector called something like "ATA/RAID and SCSI boot order" which lets you pick which of the two are booted to if both are present.
 
Yes, you can use both. You can fill up every PCI slot you have with IDE RAID cards and SCSI cards along with onboard RAID and your system should run fine.
 
With past boards Ive had, if you run the IDE raid you will not be able to use the SCSI to boot from unless there is no boot OS on the IDE drive, as the board will always give boot priority to the first SCSI device in the PCI chain which it will see the ATA controller as SCSI. If there is no bootable OS on the IDE raid controller then it should work for you I believe.

It's all data, so it should be no problem I guess.
 
I just tried with a Soyo Dragon + and an Adaptec 29160N card and had problems. But I then had problems with just the RAID portion and IDE3 and 4 with this board. Not sure if they're bum IDE channels, a problem promise controller, or a driver issue. I tried absolutely every g0dd^mn thing for 2 days to no avail.

So I ended up with both my HDD's one IDE 1 and both my DVD, CDRW on IDE 2 and forgetting about RAID for the moment. I wanted RAID0 for a performance boost, but it just wasn't worth it.

So now I'm putting the SCSI back in and it will have a 15K cheetah drive that'll be my boot/os and app's drive. I think I'll see a lot more boost out of this than RAID0 on 7200 IDE drives. And (maybe it's sour grapes) I'm telling myself that it sure would be a bizatch to lose one 120 GB drive causing me to lose the whole 240 GB array.
 
I've had IDE RAID and SCSI running at the same time. It will work. I would not recommend filling all your slots with IDE RAID and SCSI cards though. As for the boot issues, every board I've seen that has IDE RAID gives you the option somewhere to set the boot order. Some boards have the standard set boot order that allows you to put SCSI ahead of on board IDE RAID. Other boards have a simple enable/disable boot from IDE RAID in another part of the BIOS from the standard boot order menu.
 
I have Adaptec SCSI 29140 and ACARD IDE RAID 6880, on Shuttle AK31a m/b. Works fine. Before getting the ACARD, Promise tech support said there would be conflict between Promise and Adaptec, which is why I tried the ACARD (less expensive than Promise anyway, and also support ATA/133).
