SCSI boot problems

[Galactus]

Hi! In one of my computers i just plugged in a scsi card. Problem is, it wont boot from the scsi disk. I think the problem is, there is a ide raid card in it too. From what i know, the system recognises the raid card as a scsi card? If that is the problem, is there a way to solve it?

SCSI card -> Tekram DC390U2W
IDE card -> Iwill SIDE-RAID100

try moving the scsi card so that it's further from the agp slot than the raid card!

Check your boot order in the bios.
I can change between floppy, CD, ide, ide-raid and SCSI.

Also try to disable all your IDE drives completely - if your
PC does not boot from SCSI then, there is maybe no system
installed?

bacillus: ok, will try that when I get home.

woolmilk: i cloned the ide system drive to the scsi drive, so it should be there

I haven't really done any research to validate this, but from what I know, IDE and SCSI are completely incompatible. If you try and run an IDE drive and a SCSI drive in the PC, it will only see the IDE drive. Basically, it's either all SCSI or no SCSI.

I've had the same problem a year ago when migrating from IDE to SCSI.. it would never boot from the SCSI drive. It would see it, but it wouldn't boot from it. Like the IDE drives hold a priority over SCSI.

Tarmax: its no problem mixing ide/scsi. I have both on this machine, and have had similar configs before. But thats with onboard ide controllers. In this case, its a ide raid pci card, and probably the system treats the ide card as a scsi one as well, and tries to boot from that.

ahh ok.. my mistake..

but given your current situation, the same still holds true.. right? all SCSI or no SCSI

would I be correct in assuming you're using XP? well, either way, it all depends on which the OS sees first because regardless of which it sees, it sees it as a mass storage controller... and.. you probably already knew that, right?

lol.. i tried =/

Tarmax: It doesnt even start loading the OS

It says error non system disk or something. Probably because it tries booting from the hd's on raid card, where there is no system

ok, that helps!

It's a problem in your BIOS. Like woolmilk said, try and change the boot order.

What kind of mobo??

If it's a recent motherboard (say, within the past year or 2 I guess), there should be an option in the boot order for RAID/SCSI, and another option dictating which of those to boot from (RAID or SCSI). But it all depends on the kind of BIOS used in the mobo.

Its an old BX440 board, the asus bx6 2.0

only options are a,c,scsi i think

Usually the system boots in order of onboard controller, then from the first slot down. I would place the SCSI controller nearest the top and the IDE Raid controller farther down. This is why some peeps cant get their SCSI add in cards to boot, because they have an onboard IDE ATA controller with a bootable OS installed. The system sees the onboard ATA controller as the first SCSI bootable device.
