View Full Version : Can't install XP on scsi hard drive...

02-27-2004, 09:21 PM
I'm trying to install XP Pro on a system with a scsi hard drive (no other hard drives in my system), but when the install gets to the point where you usually pick which drive to install the OS to, it says that my computer has no hard drives.

I've tried using win98, winME and winXP boot floppies, and they have no trouble seeing the hard drive. But winXP install doesn't see it.

I have an adaptec 1540 ISA scsi card. So I also tried installing the drivers during XP install (by pressing F2 or F6, I forget which). XP has a driver for my scsi card, but when I try to install it, it says that there is no such card in my system!

Also tried XP boot floppies, but result is the same as using the CD.

any thoughts?

XP doesn't really like ISA devices...especially if they aren't PnP ISA.

If possible you may want to move up to a PCI SCSI card or skip XP on this machine.

Was able to figure it out.

I had the SCSI card using IRQ 9, which WindowsXP uses for ACPI.

Changed the SCSI card IRQ and I'm all good!

thanks all...

Lucky you... :D

That is one of the reason XP doesn't like nonPnP ISA devices, because it assigns IRQs differently than older versions and it even adds a few more virtual ones to cover more devices, but that all requires PnP to operate smoothly.
